Abstract

t seems promising and relevant to consider digital processes of industries and complexes in the context of the digital transformation of a region, which encourages the region's sustainable development. Due to the digitalisation of the construction complex of a region we can evaluate the digital infrastructure development at the design and production stage (i.e. from the design documentation to the commissioning of facilities). The basis for the digitalisation of the construction complex is BIM technologies, which should be transferred from the micro level to the meso level (the level of a municipality or region) and later to the macro level (the level of the entire country). The study aimed to analyse and estimate groups of quantitative factors that characterise the digital potential of the construction complex. The research methods included quantitative and qualitative analysis. A comparative analysis of factors (i.e. indexes and rankings) was performed, and the groups of factors were ranked to determine whether regions are ready to digitalise the construction complex. This was done in accordance with expert assessments based on the results of a survey. The study compared the previously identified quantitative and qualitative factors with each other in order to eliminate duplication of the components of the qualitative factors, such as indices and ratings. Consequently, a necessary and sufficient sample of the factors was formed. This sample can be further used to correctly rank the degree to which Russian regions are prepared to digitalise the construction complex. To rank the factors to measure their importance and significance, the survey was conducted by groups: 1) socio-economic conditions for industry digitalisation; 2) development of science and innovation in the regions; 3) development of the construction complex in the regions; and 4) development of digital technologies in the regions. Based on the survey, the selected factors were ranked, particularly by groups. The results of this study can be used to refine the ranking of the regions' degree of readiness for the digitalisation of the construction complex as well as to determine the effectiveness of the ranking.

Аннотация

Рассмотрение цифровых процессов отраслей и комплексов через призму цифровой трансформации региона является перспективным и актуальным, что в дальнейшем способствует устойчивому развитию региона. Цифровизация строительного комплекса региона позволяет дать оценку цифрового инфраструктурного развития на проектно-производственном этапе, т.е. от проектной документации до ввода объектов в эксплуатацию. Основой цифровизации строительного комплекса являются BIM-тех-нологии, которые должны транслироваться с микроуровня на мезоуровень - уровень муниципалитета/региона, а в дальнейшем и на макроуровень - уровень всей страны. Целью исследования является анализ и оценка групп количественных факторов, характеризующих цифровой потенциал строительного комплекса. Методами исследования являются методы количественного и качественного анализа, которые заключаются в проведении сравнительного анализа факторов - индексов и рейтингов, а также в ранжировании групп факторов характеризующих готовность регионов к цифровизации строительного комплекса в соответствии с экспертными оценками по итогу проведенного опроса респондентов. Проведенное исследование позволило сопоставить ранее выявленные количественные и качественные факторы между собой, с целью устранения дублирования составляющих качественных факторов - индексов и рейтингов. Следовательно, была сформирована необходимая и достаточная выборка факторов, которые в дальнейшем могут быть использованы для формирования скорректированного рейтинга по уровню готовности регионов России к цифровизации строительного комплекса. Для ранжирования факторов оценки цифрового потенциала строительного комплекса региона по важности и значимости был проведен опрос респондентов по группам: 1) социально-экономические условия для осуществления отраслевой цифровизации; 2) развитие науки и инноваций в регионах; 3) развитие строительного комплекса регионов; 4) развитие цифровых технологий в регионах. В соответствии с проведенным опросом респондентов отобранные факторы были ранжированы, в т.ч. по группам. В дальнейшем, данное исследование позволит сформировать уточненный рейтинг уровня готовности регионов к цифровизации строительного комплекса, а также определить границы эффективности рейтинговой оценки. Ключевые слова: цифровая экономика, цифровой потенциал, устойчивое развитие, региональное развитие, строительный комплекс, BIM-технологии.

1. Introduction

Digital transformation encourages regional development and contributes to socio-economic growth (Lygina, 2019; Chernykh et al., 2019). Measuring the digital potential of sectors and complexes is a primary objective in the formation of regional innovation systems, which build up and ensure the development of innovation potential

Measuring the digital potential of industries and complexes is a key task in stimulating the growth of regional innovation systems. These systems, together with the national innovation system and a system providing a mechanism for effective operation of the innovative economy, contribute to the development of the innovative potential of enterprises in the region (innovative infrastructure, innovation security, government regulation). In turn, this becomes a structural component of the economic development of the state, namely, the institutional foundation of the country's innovative economy (Litvinenko, 2015; Volkonitskaya and Lyapina, 2014; Rodionov et al., 2013). Regional technological planning institutions can be used to develop regional innovation systems. They are oriented on regional-specific industries, which have a relative competitive advantage due to their territorial position, as well as on the development of appropriate strategies to support these industries (Park et al., 2021). It is important to determine the potential for digital transformation of a particular territory, and thus the readiness for digitalisation must be evaluated within the sectors and complexes of the economy that define the specialisation of regions.

Digital technology is being actively introduced everywhere in sectors and complexes, for example, in the energy sector (Nguyen et al., 2021; Konovalov, 2020), the agricultural sector (Akma-rov et al., 2021; Pfeiffer et al., 2021; Kovaleva, 2019), health care (Iakovleva et al., 2021), education (Akulenko et al., 2021; Ivanova et al., 2021) and construction (Tereshko et al., 2021; Muñoz-La Rivera et al., 2021; Berlak et al., 2021). One of the leading and rapidly growing sectors in the digital economy is the construction industry. It applies innovative technologies, with routine processes being digitalised and robotised, and work is optimised at various stages of the life cycle of a construction project1. Advanced technologies transform the process, in which working groups are organised and the work is systematised. The process, aimed at reaching strategically important goals given the sectoral specifics of the construction industry, from design documentation to the commissioning of capital development projects, should be called a construction complex (Tereshko and Rudskaya (Digital potential...), 2020). In the future, digital development of the construction complex at the regional level will bring about balanced agglomerations that can meet the challenges of modern society. Consequently, digital transformation of the construction complex can be seen as a driver of regional innovation systems, whose development is essential at the micro-, meso- and macro levels (Tereshko and Rudskaya (Digitalization of the construction., 2020) of the digital processes evolving in the sector.

It should be noted that the indicators for the development of territories (regions) are influenced by the development of enterprises that operate in the area. Thus, construction enterprises that form the construction complex of a region play a significant role in sustainable regional development, as evidenced by the numerous studies (Stanitsas and Kirytopoulos, 2021; Ilhan and Yobas, 2019). Thus careful strategic planning and development of industrial complexes in the regions, particularly the construction complex, facilitates the formation and development of a sustainable urban environment (Vargas-Hernández, 2021; Ametepey etal., 2020; Kozlov etal., 2019).

Previously, the authors conducted a study entitled 'Readiness of Regions for Digitalization of the Construction Complex' and suggested a ranking of the regions' readiness to digitalise the construction complex (Tereshko et al., 2021). The ranking relies on quantitative and qualitative factors. The qualitative factors include surveys, rankings and indices. Using an aggregated assessment of several parameters, the rankings and indices can give a summarised specification for a constituent entity, which is convenient for ranking and calculating the indicators of territories. However, the indicators that form a particular ranking or index can recur and lead to a distorted interpretation of the final outcome. Therefore, these qualitative factors must be revised to form the necessary and sufficient sample by group, mainly based on the quantitative data available.

The aim of the study is to validate the factors that constitute the ranking of the regions' readiness to digitalise the construction complex in Russia to prevent the quantitative indicators included in the qualitative factors from being duplicated. In accordance with this aim, the following objectives must be achieved: 1) analyse the composition of controversial qualitative factors; 2) form the necessary and sufficient sample of parameters for characterising a concrete group of the formed ranking; and 3) assign weights to the formed sample of factors by group in accordance with the respondent survey.

2. Literature Review

The digital development of the construction complex relies on building information modelling (BIM) technologies. BIM implies that an information model of capital development object is built at all stages of the life cycle of a construction project (Rybin et al., 2019). BIM technologies are the basis for digital transformation of the construction industry at the micro level — the level of organisations and enterprises. Interconnected operation in a digital environment, which links the design stages (concept, detailed design, project documentation, detail engineering design documentation, executive documentation) with financial, economic and investment components helps to generate a comprehensive model at different stages of the life cycle. It is an integral part of creating an information system of municipalities and regions (Pertseva et al., 2017).

Scientists from all over the world study BIM technologies and suggest various research ideas, from improving the organisational structure to adapt it to work with BIM to structuring the algorithms to model specific processes in the design of buildings and structures. For example, Alshorafa and Ergen (2019) consider the use of BIM technologies in large-scale projects. Further, Sekisov (2019) and Lushnikov (2015) examine the effectiveness of construction production organised using BIM technologies as well as the problems and advantages of their application in construction companies. Akram et al. (2019) study bibliometric and scientific-metric databases and conclude that visualisation is the most promising function of BIM, while hazard identification is an important area where these technologies can be used to ensure construction safety.

It is challenging to research the digital transformation of the sector, the investment and construction complex and the construction complex of the region. Having analysed the studies in the SCOPUS reference and abstract database matching the search query 'Digitalization of the construction industry' filtered by the keyword Digitalization, 54 documents were identified from 2009 to 2021. Figure 1 shows the distribution of studies by year. It should be noted that the peak in publications in 2019 and their decline in 2020-2021 suggests that the process of indexing articles is often time-consuming, and therefore the sample for 2020-2021 will be gradually updated.

Figure 1. Researching the digitalisation of the construction industry by year in the SCOPUS database

Most of the studies on the digitalisation of the construction industry were written by authors from Germany (18 publications), Russia (8 publications), Australia (3 publications), the Czech Republic (3 publications) and the UK (3 publications). The following leading scientists in this field can be mentioned: Hosseini, Aghimien, Aigbavboa, Helmus, Jahanger, Kelm, Louis, Matejka, Zhou, Meins-Becker, Stoyanova, Oke A.E., Pestana, Stransky and Trejo. For example, Stoyanova (2020) studies advanced digitalisation practices in industrial sectors, using a selection of factors related to success potential and proposing recommendations to determine whether the digital technologies used in construction are successful.

Elghaish et al. (2020), Aghimien et al. (2019) and Golizadeh et al. (2019) show how pilotless flying vehicles and immersive technologies can be used for digitalising the construction industry and discuss the potential applications of these technologies individually or combined and integrated with each other. In their work, Aghimien et al. (2020) evaluate the aspects of the latent institutional environment that affect the digitalisation of the construction industry in South Africa. Meanwhile, Oke A. et al. (2020) analyse the challenges when the Internet of Things was introduced in the construction industry in Nigeria in order to increase awareness of and the degree to which the advantages were used by stakeholders.

Additionally, Zhou et al. (2020) describe a digital process platform that supports a wide range of users in the construction market. This platform provides more data about construction market players using an integrated cyber-physical system and contributes to the standardisation of communication infrastructure within the construction sector by combining various solutions based on information and communications technologies.

Assessing the development of the digital potential of the construction complex of the regions is advantageous, as in the initial stage it can be used to identify the regions prone to digital transformation, those that have a good technological base in their toolkit and the organisations developing together with the rapidly changing trends. No studies measuring the digital potential of the construction complex have been identified. Consequently, it is important to form the necessary and sufficient sample of factors to assess the potential of the territory or subject of the federation of a particular country, including the regions of Russia, for digitalising the construction complex.

3. Materials and Methods

The research methodology relies on qualitative and quantitative methods. Qualitative research methods involve validating the factors that characterise the regions' readiness to digitalise the construction complex, using a comparative analysis of the qualitative indicators - indices and rankings - in order to avoid duplication of the designed parameters of the sample that are used to measure the digital potential of the regional construction complex. The following ones were selected for the analysis: 1) Business Digitalization Index by constituent entities; 2) ranking of the socio-economic position of the constituent entities of the Russian Federation (RF); 3) Science and Technology Development Index; 4) innovative development ranking of the RF regions; and 5) ranking of innovative regions in Russia. These quantitative indicators assess the regions using the aggregate parameters of digital and innovative development.

The quantitative methods involve ranking the groups of factors that characterise the regions' readiness to digitalise the construction complex, using expert assessments from the survey of respondents. The assessment algorithm includes the following stages:

Stage 1. Conducting an online survey of respondents.

Stage 2. Analysing the results of the survey by groups of the formed assessment indicators.

Stage 3. Calculating the arithmetic mean value for the groups of factors and for individual parameters. Assigning ranks to the groups of indicators and the indicators within groups or subgroups.

4. Results and Discussion

The sample of factors previously presented in the study of Tereshko et al. (2021) can be used to reflect the necessary and sufficient characteristics for measuring the digital potential of the construction complex in a particular region of Russia. The measured digital potential is the basis for sustainable development of Russian regions (Jovovic et al., 2017; Feldhoff, 2002; Roberts, 1994; Zaborovskaya et al., 2019), as it provides a foundation for defining and developing the concept of digital transformation of the construction complex in these regions. This approach is useful because it leads to demonstrative indicators achieved through ranking the regions. Further, it simplifies the evaluation of possible scenarios for the development of the socio-economic system and can be used to build a long-term strategy for digital industrial development of the region by establishing development frameworks for the sectoral economy in the RF. The factors chosen for the ranking include both quantitative and qualitative indicators (Table 1).

Let us consider the groups of factors in more detail so that the calculated parameters are not misinterpreted when the ranking is compiled. This is important because these parameters can be based on the same quantitative data that form the qualitative indicators. The major quantitative factors to be considered are in groups 1 and 2: 'Socio-economic conditions for sectoral digitalisation of the regions' and 'Development of science and innovation in the regions', respectively.

To validate the factors in the first group, let us consider factors X3 and X4. Quantitative indicator X3, 'Index of business digitalisation by constituent entities'2, includes the following indicators: 1) The specific weight of organisations (among other organizations), using broadband Internet (%), cloud services (%), RFID technologies (%) and ERP systems (%); and 2) The specific weight

These indicators are important for assessing the digital equipment of organisations in Russian territories, including construction enterprises. Regarding the data available in the Rosstat databases, the relevant statistics for the regions of Russia in 2019 do not include a subsection for the selected index parameters. Consequently, the index will not be valid in the future. Thus, for factor X4 we have to introduce a group of indicators to assess the digitalisation of business in the regions of Russia. These indicators include the specific weight of organisations, using (as %) 1) broadband Internet; 2) CRM, ERP and SCM systems; 3) electronic document management systems; 4) cloud services; and 5) local computer networks.

Factor X4 - 'Ranking of the socio-economic situation of the RF constituent entities'3 - includes four subgroups of quantitative indicators: indicators of the scale of the economy; indicators of economic efficiency; indicators of the public sector; and indicators of the social sphere. The composition of the indicators gives quite an accurate picture of the socio-economic development of a particular Russian territory, which is one of the key aspects in measuring sectoral digitalisation. The quantitative indicators included in the subgroups are publicly available on the Rosstat website4, where they are updated annually. The agency RIA rating constitutes the ranking annually. Therefore, this qualitative indicator can be used in the future, among other things, for convenient cumulative use of quantitative data for the socio-economic block.

Let us consider the following qualitative indicators outlining the development of science and

innovation in the Russian regions (X5, X6 and X7). These indicators may have repeated values that negatively affect the final ranking and present a distorted interpretation of the results. Therefore, it is necessary to scrutinise the factors that make up the group 'Science and Innovation Development in the Region'. Accordingly, we perform a comparative analysis of the qualitative factors and examine the indicators they include in detail.

The Science and Technology Development Index (X5), formed by the agency 'RIA rating'5, includes four subgroups of indicators: human resources; physical infrastructure; the scale of scientific and technological activities; and the effectiveness of scientific and technological activities. The positions of the RF constituent entities in the final list were determined using the integral index, calculated by aggregating the ranking points of the regions for 19 analysed indicators, which were combined into the four subgroups listed above. Table 2 presents the analysis of the index and reflects the factors to be included in the assessment of the digital potential of the construction complex.

The indicators included in this index can be freely accessed on the Rosstat database, which is the advantage of using the index in the future. The final index can vary from 1 to the maximum value of 100. The index is updated annually, and the ranking of Russian regions is based on it.

The ranking of innovative development of the Russian regions6 (X6) is published by the Institute for Statistical Studies and Economics of Knowledge of the National Research University -Higher School of Economics (HSE), the Russian Cluster Observatory. The rating analyses the innovative development of the Russian regions and considers a number of ranking assessments. The ranking includes five groups, each of which is divided into subgroups. In total, the ranking includes 53 quantitative and qualitative indicators. The ranking is divided into the following indicator groups and subgroups: 1) socio-economic conditions for innovation; 2) scientific and technical potential; 3) innovative activity; 4) export activity; and 5) the quality of innovation policy. Table 3 provides an analysis of the index, reflecting the factors that should be included in the assessment of the digital potential of the construction complex.

The ranking reflects the whole picture of innovative development in the Russian regions. However, it includes some qualitative indicators that are hard to collect if no relevant ranking has been published yet.

The ranking of the innovative regions of Russia7 (X7) was formed by the Association of Innovative Regions of Russia (AIRR) and includes four groups of indicators: research and development; innovative activity; socio-economic conditions for innovation; and innovative activity of the region. The ranking includes 29 indicators. Let us have a careful look at the ranking groups in Table 4 and focus on the factors that should be accepted to assess the digital potential of the construction complex.

Similar to indicator X6, the ranking of the innovative regions of Russia fully reflects the digital development picture. It is generated on a regular basis and includes the most relevant information on the changes occurring in the innovation sphere of the economies of the RF constituent entities. A feature of the ranking is the presence of quality indicators, in the future, when the annual characteristics of the ranking are updated, it may have a negative effect due to the lack of data. Factor X7 is similar in content to factor X6. Therefore, using these two parameters in the sample is redundant.

In the comparative analysis of the qualitative indicators presented in the sample of the second group of factors, which characterise the level of readiness of the Russian regions to digitalise the construction complex, a number of repetitive ones factors can be highlighted: X5.1.2=X6.2.2.2; X5.2.2=X6.3.1.1=X7.2.1; X6.3.2.1=X7.2.3; X5.2.6=X6.3.3.1=X7.2.9; X5.4.1=X6.3.4.1=X7.2.4; X5.4.2=X7.3.4; X5.4.3=X6.2.3.2=X7.1.5; X7.1.1=X6.1.2.2; X7.1.3=X6.1.2.1; X7.1.6=X6.2.3.1; X7.1.8=X6.2.1.1; X7.1.9=X6.2.1.3; X7.2.5=X6.3.4.2; X7.2.7=X6.4.2.2; X7.2.8=X6.2.3.3; X7.3.1=X6.1.1.2; X7.3.2=X6.1.1.1; X7.3.3=X6.1.1.3; X7.4.1=X6.5.4.3; and X7.4.2=X6.5.4.1. As you can see, the indicators in the three groups have intersections by the same parameters. Consequently, the previously selected quantitative factors X5, X6, and X7 cannot be used in the aggregate. In addition, the factor 'Ranking of innovative development of the RF regions' contains indicator X6.1.3.1, which is identical to the indicator from the first group of factors - 'Specific weight of organisations using broadband Internet (%)'. The group of factors 'Development of digital technology in regions' has to be supplemented with the quantitative indicator 'Specific weight of organisations using design software (%)', which reflects the information support of construction complex enterprises with software products necessary for carrying out design processes in accordance with BIM technologies.

Let us form the necessary and sufficient sample of factors for the subgroups in order to assess the level of readiness of the Russian regions to digitalise the construction complex. The key requirement for the factors is their availability and annual update (Table 5). The factors for the group 'Development of Science and Innovation in the Regions' are revised based on a detailed analysis of the indicators included in the index and rankings. Thus, we can form the necessary sample of available quantitative indicators, which are divided into subgroups within the group. We keep the index of scientific and technological development, as it is updated annually, is minimally sufficient for measuring the potential of the constituent entities and the data it contains are freely accessed from the Rosstat state statistics base.

introducing the assessment of publication activity in the Web of Science as an additional parameter. The educational potential of the population, previously included in the ranking of innovative development of the RF regions, is also revised. Given the implications of the factors characterising the educational potential, the sample of quantitative indicators within the subgroup 'Educational potential of the population' is assigned to the first group of factors.

In order to rank the selected factors and then correctly assess the level of readiness of the regions to digitalise the building complex, the authors conducted a surveywith 49 specialists . The interviewees are experts in the field of construction and are engaged in management, pedagogical or administrative activities. In terms of their geographical distribution, all the respondents belong to St. Petersburg, Leningrad Region, Moscow and Moscow Region. The survey was conducted for the following groups: 1) Socio-economic conditions for sectoral digitalisation; 2) Development of science and innovation in the regions; 3) Development of the construction complex of the regions; and 4) Development of digital technology in the regions. Within each block, the respondents assessed the characteristics that affect the development of a particular block in the context of the construction complex digitalisation. Blocks were assessed using a ten-point scale, where 1 indicates a low level of significance, and 10 indicates a high level of significance. The groups of factors, subgroups and/or factors included in the groups were ranked based on the total distribution of assessments in accordance with the arithmetic mean parameter. The arithmetic mean value for the groups was adopted as a calculation method. For example, to perform calculations for the first group consisting of factors X1-X5, expert assessments on a 10-point scale were considered. Then, the arithmetic mean value was considered for each factor (X1 is 7.367; X2 is 6.041; X3 is 7.694; X4 is 7.735; X5 is 9.000), and in accordance with it the weight was determined using some parameter within the group (X1 is 0.195; X2 is 0.160; X3 is 0.203; X4 is 0.204; X5 is 0.238). The parameters for each group of factors were calculated in a similar way. Then, the weight was calculated for each group in accordance with the arithmetic mean of the factors in this group. For example, for group 1 the total arithmetic mean is 7.567, for group 2 it is 7.827, for group 3 it is 6.827 and for group 4 it is 8.106.

Table 6 contains the weights calculated by group and by indicator. In addition, a significance rank was assigned to each factor, where 1 indicates the greatest significance. The rank was determined both between the groups of factors and within the indicators/subgroups of indicators.

In future research, a correlation and regression analysis of the indicator sample has to be carried out to determine how the indicators affect the development of the region. We also plan to study the efficient frontiers of the formed ranking indicator using the DEA shell analysis method to develop more accurate ranking indicators in the future. The ranking itself will further be used to form a mechanism for strategic development of the digital potential of the construction complex in Russian regions in conjunction with the regional innovation system.

5. Conclusion

This study validates the factors that were previously identified as important for assessing the readiness of regions to digitalise the construction complex in order to avoid: 1) duplicating the indicators within qualitative factors - rankings and indices; and 2) using data inaccessible through Rosstat (i.e. those that are no longer collected or published in the open government statistical database). In addition, a necessary and sufficient sample of factors was constructed. An updated ranking for measuring the digital potential of the construction complex of Russian regions using the fuzzy sets method could be considered in the future. Additionally, the identified group ranks of factors and indicators included in these groups will be used to form the ranking, and the calculated parameters will be adjusted considering the weighted average values and priority ranks. Therefore, the study is unique for Russian territories and contributes significantly to the methodological assessment of the digital development of the construction complex of these territories. Research of this kind is rudimental so far. The study suggests the data that could be used for assessing the readiness of regions to digitalise the construction complex. Moreover, these data can be used to track the development at different levels of management.

It should be noted that the research results are of international interest. The proposed selection of factors for measuring the digital potential of the construction complex of a territory can be translated from the micro to the macro level to make comparisons between various countries. Consequently, in the near future an international ranking based on the formed sample of factors could be compiled to measure the degree to which countries are ready to digitalise their construction complexes.
