Complex Modelling of Regional Tourism Systems

1. Introduction

The economic crisis caused by the pandemic has significantly affected the market of services and

consumer goods (Hordofa et al., 2022). The business found itself in unusual conditions of isolation from

consumers. In this continuously changing epidemiological situation, there is a need to use alternative

measures to attract customers and analyse their new urgent needs. The governmental measures to restrict

work and limit entry to public places and unpredictable consumer behaviour – all of it demands the need

for flexibility and rapid adaptation to new conditions. Such an approach applies not only to the individual

representatives of the industry but also to the industry as a whole. The tourism industry, the part of the

economy most affected by the pandemic, needs flexible management methods, which can be provided

only if there is a flexible forecasting system that can change along with the outside world. Since no

part of the economy can exist separately from the outside world, it is necessary to consider the tourism

industry by examining a country’s general economic situation. The development of tourism infrastruc-

ture has fundamental importance for individuals – it is a tool to combat unemployment (new jobs) – for

entrepreneurs –they can ensure the need for tourist products – and for the country’s economy – tourism

is an indicator that affects investment attractiveness and the level of people’s well-being (Esfandiar et

al., 2019). At the same time, uncontrolled development of tourist infrastructure can significantly harm

the environment and culture (Berawi et al., 2016; Widaningrum et al., 2020). From this point of view,

the issue of developing a general model of domestic tourism has been presented as the only competent

approach to stimulate the tourism industry for sustainable development. This article examined the expe-

riences of foreign researchers in modelling tourist flows. The articles that modelled domestic and inter-

national tourism were selected for analysis. In selecting the sources, emphasis was given to the articles’

relevance in the field of tourism in general and in terms of the modern technologies and data used. The

availability of reasonable results, considering the provision of data on statistical errors/deviations, was

also emphasised.

This study also paid special attention to the prospects of using CGE models and, in particular, an

approach to forecasting revenue from domestic tourism based on the income groups of the population.

The revenue from domestic tourism is a key element of the domestic tourism model, which describes the

relationship between the stabilisation of the region’s economic indicators and the degree of development

of domestic tourism. The model was developed using synthetic data, which is as close as possible to real

data. The data obtained from the various open sources form a network that includes a region’s economy,

the level of citizen well-being, and the state of the regional tourism sector. This is the first study to offer

results regarding an initiative project to develop a regional model of domestic tourism.

2. Literature review

Based on the research goals, we defined the basic rules for finding suitable sources. First, we limit-

ed the search queries to the field of tourism in general and the modelling of tourist processes in particular.

We selected the sources from the Scopus database using the keywords “tourism” and “model”. Next, we

selected the most cited reviews (with at least 20 citations) in the last six years (2017–2022) that were

most relevant to our topic. When we found a relevant article, we also analysed its lists of sources to eval-

uate the results of the described model that is based on several studies. As a result, we selected articles

that described the model or approach most profoundly for further analysis. Thus, our review included

articles from a much earlier period. For the analysis, it is worth noting that we considered articles that

were not only about domestic tourism but also international tourism.

Among the variety of articles on modelling in the field of tourism, it was important to choose the

most applicable ones for forecasting tourist flow. Accordingly, we repeated the procedure for selecting

articles but changed the combination of the keywords: “tourism” and “demand”.

The tourism sector includes varies types of tourism based on goals, types of tourists, and other

classifications. Based on the United Nations World Tourism Organizations (UNWTO) methodology, we

assumed the importance of models that allow us to predict the behaviour of tourists depending on their

needs and preferences. At the next stage of the literature selection, we thus focused on examining tourist

processes and analysing tourist behaviour. Thus, the review included articles modelling tourist routes or

the satisfaction of a tourist from visiting attractions. It is important to note that the models of the Autore-

gressive Integrated Moving Average (ARIMA) and artificial neural networks (ANN) families were the

most common among the analysed sources. To ensure diverse results, we tried to select the most typical

articles describing these models, while the rest were not included. The final choice of the articles also

depended on the availability of a comparison of the results within the same study, a requirement that was

dictated by the complexity inherent in comparing different scientific papers.

The review included 36 articles: five articles discuss the mutual influence of economic growth and

tourist infrastructure, and 31 articles describe the forecast models of tourist flow or other tourist process-

es. The selected models were divided into four types: simulation models (22%), econometric models

(42%), deep learning models and neural networks (14%), and hybrid models (22%) (Table 1).

Simulation models

Simulation models allow replacing the system under study with a model that describes system’s

behaviours and its key indicators. This approach ensures the transparency of the processes occurring

within the system, which means that it allows one to predict the development of the system by consider-

ing the changes in its various indicators. The analysed articles we analysed used two types of simulation

models: system dynamics and agent-based modelling.

Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5 70

Complex Modelling of Regional Tourism Systems

The system dynamic model is used as an alternative to forecasting models for the scenario-based

planning of tourism destinations (Mai et al., 2018). The advantage of this model is its ability to consider

a system’s natural limitations, indicating that the classic approach, while capable of accurately predict-

ing the growth rate, does not consider the possible negative consequences of excessive or too rapid de-

velopment of a destination (overpopulation, flooding, shortage of drinking water sources, etc.).

Simulation models are ideal for analysing the risks and prospects of certain management deci-

sions. The use of the computable general equilibrium (CGE) model adapted to the tourism sector allows

for the assessment of the most promising investment directions in terms of the subsequent effect on the

country’s economy and the durability of the results (Blake, 2009).

Simulation modelling is often based on econometric models as an upper-level superstructure

that allows the interpretation of the results and establishing logical connections (Wu et al., 2021). The

time-varying parameter panel vector autoregressive (TVP-PVAR) model in combination with scenario

modelling shows the results calibrated on historical data. This approach allows to evaluate the quality of

the forecast and choose the optimal planning horizon.

Another approach to the simulation of tourist processes is agent-based modelling. The basis of

research in such works is the study of behavioural factors that determine the rules of the behaviour of

agents (tourists). In Li et al. (2021), there exists a parallel between the tourist’s tendency to optimise and

his tourist route.

The most common model created specifically for describing travel agents is the Plog model. The

model describes tourists in terms of their psychotype and behaviour, distinguishing two types with in-

termediate subtypes: adventurers and psychocentrics. According to the typology of Plog, psychocentric

people tend to visit popular proven places, while adventurers will explore local features and stay away

from tourist areas. It is assumed that the number of visitors changes with the development of resorts

(Griffith et al., 1996). Santoso et al. (2020) used behavioural factors to determine the degree of satisfac-

tion tourists gained from visiting the main attractions in Indonesia. However, a limitation of the Plog’s

model is that it ignores the tourists’ motivations, activities, and modes of transport (Litvin et al., 2016).

Econometric models

The better part of analysed models were econometric models. This type of model involves analyt-

ical tools based on mathematical and statistical modelling, allowing managers to make managerial de-

cisions based on accurate forecasts. The largest number of the analysed articles used regression results,

with the most typical representative of the regression models being the MIDAS model. The MIDAS

model consists of only one equation, and while this does not allow the model to analyse the pairwise

correlations between indicators, this makes it less prone to specification errors (Bangwayo-Skeete et al.,

2015).

Regression is a productive and convenient tool for analysing the correlations between indicators.

Song et al. (2010) used the autoregressive distributed lag (ARDL) to analyse the elasticity of tourists’ de-

mands in Hong Kong from a set of indicators (income level, search queries, and advertising costs). The

study found a long-term relationship between demand, income, and prices, demonstrating that tourists’

income levels are the most important factor determining tourism demand in the long term.

Econometric models may also be used to analyse bottlenecks. In Harb et al. (2020), the gravity

model was used to confirm the need to use multi-lateral resistance to tourism (MRT) when assessing the

attractiveness of a tourist destination. The classical models, the researchers noted that, did not consider

the attractiveness of the alternative directions expressed in the MRT indicator. Integrating the gravi-

ty model with the common correlated effects (CCE) proved the need for analysing data to detect the

magnitude of cross-sectional dependence and, when the latter is omnipresent, employing MRT-robust

estimations.

71 Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5

Gintciak, A., Burlutskaya, Zh., Zubkova, D., Petryaeva, A.

Another approach is demonstrated in the study of tourist flows in Portugal, which used a factor

model based on data processed by the Least-Angle Regression algorithm (LARS-EN) (Lourenço et al.,

2021). For each country, the algorithm identified the most significant factors, which made it possible to

increase the accuracy of forecasts. The researchers highlighted the usefulness of survey data in predict-

ing tourism.

Inventive research was conducted on analysing the demand for dark tourism based on the statisti-

cal data on age, average income, and education level (Millán et al., 2021). The Seasonal Autoregressive

Integrated Moving Average (SARIMA) model demonstrated the demand for visiting Cordoba with an

error of 5%. SARIMA also surpassed the Grey model in forecasting tourist demands (Sharma et al.,

2020). The Grey model family showed statistically significant results in forecasting tourism demand

in Vietnam, but it demonstrated different accuracy for different countries (Nguyen et al., 2019). Some

advantage over SARIMA was demonstrated by the KS-AR model, which combines kitchen sink (KS)

modelling with the AR autoregressive model (Nicholas et al., 2021). It is worth noting that all the studies

noted the applicability of one-dimensional models exclusively for short-term planning.

Though the VAR family of models is popular in short-term forecasts, it can also be adapted for

long-term forecasting (up to four quarters ahead). The Bayesian global vector autoregressive (BGVAR)

model tested in nine countries in Southeast Asia showed its ability to capture the spillover effects of in-

ternational tourism demand in this region (Assaf et al., 2019).

As an alternative approach to forecasting tourist demands, it is worth considering the seasonally

restacked multi-series structural time series model (M-STSM) (Chen et al., 2019). This model is similar

to the multivariate method but includes a new data restacking technique: a quarterly tourism demand

series is split into four component series, and the component series are then restacked to build a multi-se-

ries structural time series model. This method offers the best forecast accuracy compared with traditional

univariate models (ARIMA, ETC).

Among the approaches to modelling tourist demand, we can distinguish panel data models that

allow for tracking the dynamics of data changes, considering the assessment of elasticity, standard de-

viation, and other statistical indicators (Darani et al., 2018). This approach assumes that the demand for

tourism depends on a country’s macroeconomic indicators.

Danbatta et al. (2021) predicted tourist flow based on the data on the tourist’s actual arrival by a

mathematical model using a random variable generator. Thus, a model based on a Fourier series was

received at the input, which was then processed by the Monte Carlo method based on the obtained data,

and the probabilistic characteristics of the process under consideration were calculated. The forecast was

considered statistically significant.

The most complete multidimensional analysis was presented in Turner et al. (2001). The SEM

model implies modelling with structural equations (that is, conducting a multidimensional analysis

based on regression analysis, path analysis, and factor analysis). Based on a multidimensional analysis

of various indicators (GDP, income level, etc.), it can be concluded that there are significant differences

between the independent variables that influence the demand for business, holidays, and tourist types.

These results are of fundamental importance when building a model of tourist infrastructure.

Deep learning models, neural networks

A whole series of articles is devoted to the use of machine learning for predicting tourist demand

and analysing its routes. Law et al. (2019) presented research results confirming the increase in fore-

cast accuracy when using the Deep Learning Model (DLM) compared to using models such as ANN,

ARIMAX, SVR, and so on. However, it is worth considering that these results were obtained with the

short-term forecasting of demand and cannot be unambiguously used for long-term planning without

additional research.

Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5 72

Complex Modelling of Regional Tourism Systems

An alternative way to use machine learning models is to analyse the psychological perception of

a tourist destination based on travel geotagged photos (Wang, 2020). Using Latent Dirichlet Allocation

allowed categorising the analysed content into topics and then create a polynomial distribution model.

Vu et al. (2015) used social media photos to identify the most developed tourist routes. The data

were clustered using the P-DBSCAN algorithm, and regions of interest were selected based on geo-

graphic data. Using the Markov chain, tourist trajectories were constructed.

Neural network models are also used to analyse the load of public transport. Lubis et al. (2019)

presented the approbation of a Multinomial Logit model (MNL) for predicting high-speed rail (HSR)

route loading. The developed model allows you to predict the load by considering alternative modes of

transport.

Hybrid models

The last category highlighted in this study is hybrid models. Using various econometric models

with each other or with machine learning models improves the accuracy of forecasts, because it consid-

ers both dynamically changing indicators and the impact of the macroeconomic situation.

Rafidah et al. (2020) used the support vector machine (WSVM) model and decomposition ensem-

ble model (Benchmark EMD-SARIMA and EMD_WSVM) to predict tourist flow, obtaining results that

revealed a greater efficiency of using the hybrid model than individual approaches.

The smallest measurement error was provided by a combination of MIDAS-SARIMA econometric

models (Wen et al., 2021). Based on the data on search queries for specific keywords, the model predict-

ed tourist flow with greater accuracy than the same models individually or the hybrid MIDAS-AR type.

A similar study on combining econometric models was conducted by Wen et al. (2019). The results

obtained for the Hybrid Arimax / Narx Model were also almost one and a half times more accurate than

iНе можете найти то, что вам нужно? Попробуйте сервис подбора литературы.

when these models were used separately.

However, if the source data is restricted to search queries, it is worth highlighting the DBEDBN

model. Using a deep web of trust allows one to extract the most valuable information from the initial

data. The resulting forecast is then processed by vector regression algorithms, which ensures minimum

error in the results (Huang et al., 2021).

The integration of the AR model with a big data approach was introduced in Fronzetti Colladon et

al. (2019). A specific web crawler was developed to extract information from the TripAdvisor travel fo-

rum. The crawler parsed HTML pages and extracted information of interest, with associated timestamps

to allow a longitudinal analysis. The highest accuracy of the results was achieved for the one-month

forecast (in comparison with AR, the accuracy for some cities exceeded by more than 30%), and the ex-

cess inaccuracy was no more than 5% for three months. It is important to note that the crawler produced

a significant amount of incomplete or inconsistent data for some cities.

In Silva et al. (2019), the researchers used Singular Spectrum Analysis (SSA) to account for the

seasonality of demand. The introduced DNNAR model showed better results than the NNAR model by

10%–30% for different countries. Improved results were obtained for all the planning horizons: from a

month to a year. Compared to ARIMA and ETS forecasts, the DNNAR model showed better results for

all horizons except the one-step-ahead forecast, indicating that seasonality is more problematic for NN

models.

A more structured and complete data was supported by the VAR (P) model, which considers tradi-

tional structured data (ticket information) with unstructured data (web requests). The wide range of the

data included data on infrastructure, weather conditions, and bookings in hotels, restaurants, theatres,

and so on (Liu et al., 2018). This model forecasted the changes in tourism demand in conjunction with

the intentions of tourists.

Gintciak, A., Burlutskaya, Zh., Zubkova, D., Petryaeva, A.

3. Materials and methods

The choice of the model depends on characteristics such as openness (it is necessary to consider

the external links of the system with the world as the outflow of tourists to other countries or exchange

rate) and the transparency of the results (it is important to establish the rules for the interaction of all the

internal elements of the system to simulate the economic effect depending on changes in certain indica-

tors). It seems that the most profitable approach is to combine the results of mathematical (econometric)

tools for predicting tourist flow with machine learning tools for filtering and processing big data (Liu et

al., 2018; Wen et al., 2019; Vu et al., 2015) and embed this into the simulation model (Fig. 1). At this

stage of the study, it was difficult to choose between agent-based modelling (Li et al., 2021; Santoso et

al., 2020; Griffith et al., 1996) and the system dynamics model (Mai et al., 2018; Blake, 2009), since

both approaches are equivalent in the depth and prospects of the study. It is worth noting that scenario

modelling corresponds to the goals of building a model of domestic tourism in terms of assessing the

impact of state support on the development of tourist infrastructure in the country and increasing tourist

flow. However, only agent-based modelling will help to form tourists’ profile and assess their needs as

accurately as possible. In this case, agent-based modelling is more complex and may be used in a longer

perspective.

Figure 1. A possible approach to modelling domestic tourism

Consider the block with the system dynamics model. It is proposed to use the CGE model as a

basis for modelling the tourism industry in the context of the region’s sustainable development (Blake,

2009; Gintciak, 2022).

CGE models for the tourism sector

CGE models (computable general equilibrium models) are used to ensure the equilibrium be-

tween industries in economic modelling. The more industries, regions, and consumer types appear in

the model, the more difficult it is to analytically solve the model, and numerical methods processed by

computer capacities are used. CGE models are used in various economic sectors to assess the impact of

investments on individual economic products (Blake, 2009). Among the most significant models based

on the concept of CGE models, we can single out the MONASH model of the Australian economy and

the similar USAGE model of the US economy.

Gül (2015) used a static CGE model to analyse the growth of demand in Turkey’s tourism industry

and detected the established prices, which made it possible to equalise supply and demand. The author

was thus able to find that the data obtained showed an increase in the real runway with an increase in

inbound tourism. Similarly, Blake (2006) showed that the CGE general equilibrium model, as it allows

Complex Modelling of Regional Tourism Systems

one to study the demand for tourism under various assumptions, can be used to measure the macroeco-

nomic effects of internal and external shocks in a country. The authors found this model particularly use-

ful for quantitatively assessing the effects of changes in demand or other possible scenarios. In contrast,

the CGE model, Van Truong and Shimizu (2017) demonstrated, rarely detected the transport network’s

influence on the demand in tourism activities. However, the authors maintained that the CGE model is

still quite effective despite this, which the authors advised to investigate in future studies. Since each of

the above studies proved that it is reasonable to use general equilibrium models to analyse the processes

of the tourism industry, we assume that this model can be successful used for the entire industry.

Review and classification of production functions

As part of the development of the prototype of the CGE model, we analysed international expe-

rience with using various production functions to describe economic processes using the model. In the

course of the study, the most frequently used production functions for modelling the economic growth

of the tourism industry were identified and classified.

The production functions were divided into the following:

- Microeconomic and macroeconomic;

- Static and dynamic;

- Single-factor and multi-factor;

- Additive and multiplicative.

According to the type of analytical forms, the production functions were divided into linear (addi-

tive) and nonlinear (multiplicative).

1. Leontief function (Yankovyi, 2021; Hu et al., 2020; Blake, 2006)

Characteristics: microeconomic, static, two-factor, and additive.

The Leontief function is a CES function with fixed proportions of factors and with an elasticity of

substitution equals to 0, which means that it is impossible to replace the factors of production with each

other. There is thus a restriction on deviating from the initial number of factors, which are strictly fixed

for the production of a unit of output.

This function is determined by the minimum ratio of the number of resources spent to the constant

values of production. Since it belongs to the static type of production functions, this function is intended

to model certain technologies. It is thus often used to describe small-scale or fully automated produc-

tions.

2. Cobb-Douglas function, Cobb-Douglas-Tinbergen function (Sancho, 2009; Antoszewski, 2019;

Chen and Haynes, 2015; Timilsina and Shrestha, 2008; Daniels and Kakar, 2017; Pratt, 2013)

Characteristics: macroeconomic, static, two-factor, and multiplicative.

The Cobb-Douglas function depends on the number of factors of production, their elasticity coef-

ficients, as well as the scale of production and NTP. There is an addition called the Cobb-Douglas-Tin-

bergen function. It differs from the source in that it is dynamic, i.e. time-dependent.

It turns out that time dependence is added to the expression of the Cobb-Douglas-Tinbergen func-

tion. Moreover, the final number of products is influenced by the growth rate of other industries and

factors that are not explicitly considered.

In this function, the NTP is stationary, which means that, every year, the final result will change

the same number of times.

Gintciak, A., Burlutskaya, Zh., Zubkova, D., Petryaeva, A.

The Cobb-Douglas (Cobb-Douglas-Tinbergen) function is usually used to describe medium-scale

or large-scale objects characterised by stable functioning. It is closest to real economic phenomena and

processes (relative to the Leontief and Allen functions) and is easy to obtain the estimates of unknown

parameters (relative to the CES function), although it is a CES function, which means a single elasticity

of substitution.

The function has a small drawback, like the linear function: when capital intensity converges to

infinity, labour productivity also tends to infinity, which is unrealistic.

3. Linear function (Yankovyi, 2021)

Characteristics: macroeconomic, static (dynamic), two-factor (multifactorial), additive, and het-

erogeneous.

The linear function, in addition to the number of factors of production, has dependencies on the

time and coefficients of the marginality of products related to the resources used. Most often, the linear

function is used in large-scale systems where income or output is the result of the simultaneous interac-

tion of a large number of different technologies or where the number of costs will be proportional to the

final result.

An important role in the production linear function is played by the hypothesis of the constancy of

marginal production factors or unlimited elasticity of substitution, which is not the most realistic scenar-

io. Of course, the factors may be interchangeable, but most likely not in the tourism industry.

4. The Allen function (Yankovyi, 2021)

Characteristics: microeconomic, static (dynamic), two-factor, and multiplicative.

The Allen function is used to describe the processes in which the excessive growth of one of the

factors of production leads to a negative change in output or income. This production function is usually

intended for small production systems in which there exists no possibility of replacing the resources used

because the elasticity of substitution is 0. Moreover, if the model is based on data that changes over time

(for example, several years at the same enterprise), the Allen dynamic production function is used. It

depends on time, factors of production, various coefficients, and has a degree of uniformity equal to 2.

5. CES function or constant elasticity substitution function (Sancho, 2009; Chen and Haynes,

2015; Daniels and Kakar, 2017; Pratt, 2013; Willenbockel, 1999; Klump and Preissler, 2000)

Characteristics: macro-and microeconomic, dynamic (static), two-factor (three-factor), and mul-

tiplicative.

There are various specifications of the CES function: the Solow specification, the Pitchford gen-

eralisation, and the Barro and Sala-y-Martin specification, which, since it is inconsistent and redundant,

is rarely used in practice.

The CES function is used when there exists no accurate information about the level of interchange-

ability of production factors, i.e. the exact value of the elasticity of substitution is unknown but greater

than 0. However, it is assumed that this level will not change much if the resources used are increased or

decreased, i.e. there is a property of stability at certain proportions of factors.

The CES function is more reasonable, because with capital intensity tending to infinity, labour

productivity will be limited. This indicates a more realistic description of economic systems. However,

it is difficult to obtain the estimates of unknown parameters. To do this, one needs to conduct a logarithm

analysis, and the estimates will most likely be only approximate. The CES function can be used to model

systems of any level and is universal.

6. LES function or function with linear elasticity of factor substitution (Gül, 2015)

Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5 76

Complex Modelling of Regional Tourism Systems

Characteristics: macro-and microeconomic, static, multifactorial, multiplicative.

The LES function, also called the consumer utility function, is a measure of the ratio between the

volumes of goods consumed and the level of utility, i.e. the satisfaction obtained from the consumption

of a specific set of goods by a specific consumer. Its final result is influenced by the minimum required

amount of each of the factors and the coefficient of the importance of the product for the consumer.

This production function is most often used to describe processes in which the possibility of re-

placing the factors used strongly depends on their proportions.

Macroeconomic production function (MPF) (Kamaletdinov and Ksenofontov, 2018).

Characteristics: macroeconomic, static, two-factor, and multiplicative.

The macroeconomic production function is similar to the Cobb-Douglas function, but instead of

the labour factor, labour productivity is used, which is the ratio of GRP and the number of the employed

population.

The MPF can be used for a formalised description of the work of the state, taking into account

various taxes, investments, and other expenses and fees.

7. Solow or Hilhorst function (Miao and Vinter, 2021; Attar, 2021; Ilyash, 2021)

Characteristics: macro-and microeconomic, static, multifactorial, multiplicative, and heteroge-

neous.

The Solow function differs from the CES function only in the property of uniformity (this function

is inhomogeneous). Due to this fact, the Solow function is used when the uniformity property appears

optional. Since the Solow function differs from the CES function in terms of the assumptions about uni-

formity, it can similarly be used in modelling systems of any scale.

8. Quasi-linear production of functions (Wu, 2021; Tanaka, 2022)

Characteristics: macro-and microeconomic, static, multifactorial, multiplicative, and heteroge-

neous.

In a quasi-linear function, one parameter changes linearly and the other non-linearly. If there is

no linearly changing factor, i.e. its quantity will be equal to 0, then production will continue, despite the

lack of linear resources.

This function is typical for firms with large volumes of nonlinear factors. Such productions can use

a larger or smaller amount of linear factor, i.e. they do not particularly depend on their quantity. Small

fluctuations in the value of the linear factor will not affect the final result, while fluctuations in the value

of the nonlinear parameter change the output values.

9. The Tornquist function (Issin, 2017)

Characteristics: macro-and microeconomic, static, multifactorial, and multiplicative.

The Tornquist function is called the demand function; it shows the dependence of the volume of

production on goods and services.

This function has three types. Its basic formula reflects that the amount of demand for essential

goods decreases with income growth and has a limit. The formula for the demand for secondary goods

and services is used when income reaches a certain mark. However, the volume of demand also has a

limit. As a result, the formula for elite services or luxury goods is used when an even higher threshold

in affluence is reached. However, it no longer has a limit – only the rapid growth of the function graph.

To solve the selected problem, the CES function was selected from the other considered functions.

77 Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5

Gintciak, A., Burlutskaya, Zh., Zubkova, D., Petryaeva, A.

This function offers the most realistic description of economic systems. It is also used when there exists

no accurate information about the level of interchangeability of the factors of production.

Consider the general view of the CES function (formula 1):

( A0* e ^ ( wt ) ) * ( A1* K ^ ( − p ) + (1 − A1) *L ^ ( − p ) ) ^  − γp  ,

 

=Y (1)

 

where Y – quantity of output; K – capital; L – labour; A0 – factor productivity; A1 – weighting;

p – replacement ratio; γ – uniformity; w – production growth rate due to all other factors except K and

L; t – time.

where σ is the elasticity of substitution.

4. Results

Improvement of the traditional CES function

It is worth considering that the production functions were not initially adapted for calculating the

tourist indicators. However, we decided to consider the possibility of using them when calculating the

possible revenue from domestic tourism. Since the incomes of the different population groups of a coun-

try can differ significantly, we decided to divide the population into four groups according to the data

found in open sources. We assumed that the financial capabilities of tourists can be considered as the dif-

ference in their income after taxes and spending on rent and the consumer basket, considering elasticity.

It is obvious that tourists do not spend this amount entirely on trips but we assumed that the calculation

aimed to estimate the maximum possible income from tourism.

Therefore, our next task was to calculate a tourist’s maximum possible spending. This required

adapting the production function to the tourism industry. We calculated the financial opportunities for

each tourist separately depending on their standard of living.

If, for production in the CES function, the important parameters were K (capital) and L (labour)

and Y (the quantity of products produced), then, for the tourism industry, the parameter Y will be re-

sponsible for the total income of a person, K for constant and necessary expenses, including spending

on housing area, food, transport, and other necessities, and L for the final part of the funds that the agent

can set aside for future travel.

The following formula (3) was used to calculate the data on the tourism industry.

( K ^ ( − p ) + L ^ ( − p ) ) ^  − γp  ,

 

Y

= (3)

 

where K – permanent (necessary) expenses, which include spending on rental housing and the

consumer basket; L – the maximum possible amount of money a person is willing to save (postpone) for

travel; and Y – annual income, including taxes. In this case, the unknown parameter will be L, and the

distribution of funds will depend on the trend of spending tourists.

Accordingly, the formula 4 for obtaining an estimate of the maximum possible expenses of one

tourist, taking into account their standard of living, is as follows:

L = Y ( γ1 ) – K , (4)

Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5 78

Complex Modelling of Regional Tourism Systems

The calculation formula (5) of σ using the ratio of the number of tourists in different years to their

tourism expenses is as follows:

=σ ( L0 – L1) / ( population0 − population1) , (5)

where L0, L1 – travel expenses of tourists in 2018 and 2019, respectively; population0, popula-

tion1 – the number of tourists in 2018 and 2019, respectively.

Unfortunately, at this stage, we were limited by the lack of high-quality source data necessary for

validating and refining the formula. Since work is currently underway to collect and analyse data on the

tourism industry as part of a project to develop a model of domestic tourism, at the next stage, all the

results obtained will be verified based on real data.

Initial data

The process of data collection and analysis requires separate coverage. No single unified system

exists in any country for collecting and analysing the tourism industry data. The methodological rec-

ommendations for collecting and analysing the data on the tourism industry are presented in the Meth-

odology of the United Nations World Organisation from 2008. However, each country follows its own

approach to this process. Therefore, within the framework of this model, the data obtained from various

open sources were used (Botavina et al., 2020), which could affect its quality. It is difficult to find real,

openly accessible data to make calculations. Real data, in most cases, has private access. In turn, open

sources contain data that differ in its content, since collecting tourist data is not bound by any uniform

requirements. Since we considered only the first experiments within the framework of the project on

modelling domestic tourism, we made assumptions about the possibility of using synthetic data, which

is close to real data.

It is worth noting that, during the development and testing of the prototype model, no emphasis

was placed on the use of data on any particular country, as the model is assumed to be a unified solution

for any object of research. In this case, it was necessary to focus on a developed country with stable

economic indicators and with a minimum number of tourist zones. The latter requirement was due to

the inability to obtain reliable results based on the average for different points of attraction. Based on

the stated requirements, the choice of the country for the study settled on Austria for a number of the

following reasons:

- Relative completeness of data in comparison with other countries;

- Stable contribution of the tourism industry to the country’s GDP (about 6%);

- Developed domestic tourism (at least 40% of the tourist flow);

- Stability of economic indicators;

- Relative limitations at the tourist points of attraction.

Experiments

Considering pensioners, the working population was divided into four income groups. For each

group, the maximum amount of money that could be spent on holidays in the country was calculated. It

is worth noting that the results turned out to be logically acceptable, as they did reveal an increase in the

difference in income after taxes and spending on rental housing and grocery baskets. Elasticity smoothed

the distribution of funds between the necessary expenses and tourist products, allowing us to count on

high-quality results after experimenting with real data.

Table 2 shows the results of calculating the possible revenue from tourists categorised by income

groups. The income from one tourist is the share of the salary that remains with them after paying for all

the vital needs. The data on the salary of one tourist per year, depending on the income group, is based

79 Sustain. Dev. Eng. Econ. 2023, 3, 5. https://doi.org/10.48554/SDEE.2023.3.5

Gintciak, A., Burlutskaya, Zh., Zubkova, D., Petryaeva, A.

on articles of a recommendatory nature. The approximate expenses of one tourist for the consumer bas-

ket and the cost of housing and other necessary expenses were also calculated depending on the income

group. Knowing the values of the parameters Y and K, the elasticity variable γ was selected, which of-

fered a realistic estimate of the residual amount for travel. The revenue from one tourist was calculated

according to formula (4). The authors compiled the data using open sources.

In addition to revenue, it was necessary to calculate the maximum number of trips per year to pre-

dict tourist flow. For each of the profitability groups, the cost of vacation was determined depending on

its class based on the studied materials from open sources. To unify the data for a unit of vacation, we

took 14 days. We took the average cost of a vacation by category for 14 days from open sources. We then

calculated the possible number of trips for each income group using the following formula:

Number of possibletrips = Predictable waste / Recreation coast (6)

We then rounded the resulting values to integers. Table 3 shows the results.

It is worth noting that prices in Austria are among the highest, so tourists can afford a vacation in

most other countries for a similar cost. For most countries, an additional reason for choosing domestic

tourism instead of outbound tourism is to save money.

All the calculations were implemented in code written in the statistical programming language R.

5. Discussion

Modelling domestic tourism based on the concept of CGE models is not a new solution (Deepak et

al., 2001; Blake, 2009; Gül, 2015; Blake, 2006; Van Truong et al., 2017). However, in the conditions of

a pandemic (Hordofa et al., 2022), the development of a general equilibrium model is becoming relevant

again, since it allows us to assess the object of the investigation from the point of view of the impact

on this system, and it also takes into account the mutual influence of all elements of the system on each

other. Thus, significant changes in the needs and opportunities of tourists correlate with changes at the

state level, and the model continues to develop in a coordinated manner. Since increasing the scale of the

research object increases the complexity of building a model, it is necessary to formalise the behaviour

of all the elements of the system as much as possible. A mathematical description of the dynamics of

consumer spending will allow us to assess the trends towards savings as well as to understand the natural

limitations in the possible income from tourist products.

The resulting solution allowed us to assess the financial capabilities of the population and its pro-

pensity to spend on necessities and recreation and to divide the population groups by profitability, which

is necessary at the next stage of developing the model to determine the revenue from one tourist. It is

impossible to estimate the prospects of obtaining revenue from tourism without the distribution of prof-

itability groups, indicating that it is impossible to predict tourism’s contribution to the GDP.

6. Conclusion

In this article, we reviewed the approaches to modelling tourist flows and tourist processes. We

classified the analysed models based on their type and scale. We also created a list of the most popular

indicators for analysing the tourism industry: geotagged photos, the GDP, the annual tourist’s income,

the actual arrivals of tourists, the search queries (general information about the country), the search que-

ries regarding planning (restaurants, hotels, and shops), and the psychotype and behaviour of tourists.

After analysing the articles, we selected the most promising approaches to modelling domestic tourism.

It formed the basis of a general model of domestic tourism, combining the advantages of mathematical

methods for predicting tourist flow, neural networks for data processing, and simulation models for

fully accounting for all the infrastructure elements and their mutual influence. Moreover, we analysed

the production functions for the subsequent calculation of the income of tourists from various income

groups. Based on our analysis, we selected the CES function to forecast revenue from the tourist prod-

ucts consumed by domestic tourists. We adapted this function to consider the profitability indicators,

the cost of essential goods, and the elasticity of demand for tourist services for four income groups. We

conducted the analysis on Austria’s synthetic data, which was close to the real data. Our results reveal

the estimated maximum amounts of revenue gained from one tourist for the four groups of profitability,

as well as the estimated number of trips per year, considering the recommended type of vacation for

each of the groups. Our study contributes to the initial stage of the development of the CGE model for

modelling tourism processes by considering the relevance of general equilibrium models in the context

of the economic crisis caused by the pandemic.
