State of shadow economic activity in Russian regions

Conclusion. The presence of unaccounted economic activity in all Russian regions poses a threat not only to the economic security of individual regions but also to the safe and sustainable development of the entire state. Analysis of the state of the shadow economy in Russian regions showed the unevenness of its development in different regions. To conduct an effective policy of countering shadow economic processes, it is important to identify their scale and take regional characteristics into account. Olga M. Lizina


Introduction
T he shadow economy is becoming one of the important factors in the destabilization of the economic, social, and political life of society. It is closely related to the legal activities of society and occupies a significant part of it. The study of the scale of the shadow economy is of great scientific and practical importance, due to its negative impact on the national economy.
The presence of shadow economic relations in any economic system is accompanied by certain socio-economic deformations: ineffectiveness of macroeconomic regulation, a reduction in budget revenues, an increase in structural crises, an increase in the tax burden, a worsening investment climate, a decrease in trust in the government and its representatives, a change in the values of society, and many others.
The problem of the shadow economy, its structure, features of functioning and development have been studied in sufficient detail by scientists from various fields of knowledge. The variety of approaches when choosing the criteria for correlating types of socio-economic activity to the shadow one explains the complexity of categorizing this phenomenon.
Initially, the concept of the informal sector of the economy, which is an attribute of most developing countries, is formed and developed in science. Hart, who was one of the first to study the shadow sector of Ghana, described the situation with the informal sector as follows: "Rejected by the structure of formal opportunities, people from the lower ranks of the urban proletariat are looking for informal ways to increase their incomes" [1].
The scale of the shadow economic activity and the criteria for its correlation may differ depending on the specifics of the macroeconomic situation and the established traditions in the country. The study of small business by Mead and Morrison carried out in 1990 in seven developing countries and covering 2,200 enterprises confirms this [2].
In Russia, the study of the shadow economy has been conducted since the 1980s, when its scale became obvious, and the imbalance in the consumer market required drastic changes. The specified problem was studied by such scientists as Koryagina [3], Nikolaeva and Shevyakov [4].
Within the framework of the study of the informal sector and informal economy, carried out by domestic researchers, studies by Gimpelson and Kapelyushnikov should be noted [5; 6], which examine in detail the issue of dualism in the labor market, presupposing its segmentation into formal and informal sectors. The conceptual foundations of unregistered activity are laid down in Latov [7][8][9], Barsukova [10;11]. The studies by Kosals [12] are devoted to corruption and spread of fraud; Radaev pays attention to certain aspects of illegal traffic of products [13; 14]. The structure of financial flows of the shadow economy was analyzed by Avdiyskiy [15].
The complex structure of the shadow economy does not allow the use of universal methods to measure this phenomenon. Researchers from different countries are trying to assess the scale of the shadow economy in individual regions. Among foreign studies of the scale of the shadow economy, the most recognized are the works by Schneider [16; 17]. In the study of the shadow economy in 36 developed and developing countries of the European Union, a combined approach was applied, based on an econometric analysis of extensive statistical data and an analysis of the results of surveys.
Their entire set of methods can be conditionally divided into several groups: 1. Direct methods are based on inspections by the relevant authorities, interviews, and surveys. They are actively used to identify discrepancies between income and expenses of specific taxpayers or their groups [18; 19]. Despite the possibility of obtaining sufficiently detailed information about hidden economic processes, these methods give a high probability of an estimation error, since subjective factors have a significant impact on the research results.
2. Indirect methods use indicators that reflect certain aspects of informal economic activity.
They are based on the analysis of data from ministries, departments, law enforcement agencies, and use the official statistics. The group of indirect methods consists of monetary, balance sheet, resource, expert assessment, etc. These methods are widely used to assess shadow processes at the macro level [20; 21].
3. Modeling methods allow analyzing the phenomena and processes associated with informal economic activities. The functional relationship between economic indicators and shadow processes is described by a mathematical model that makes it possible to simulate the development and estimate the volume of the shadow economy.
When applying research methods, it is necessary to take into account that there is no single method that would give accurate results for measuring the shadow economy.
According to the level of research, all methods can also be divided into macro and micro methods. This division is conditional, since all methods are actively used within the framework of various sciences, depending on the subject of research. Methods of sociology and criminology are used to study shadow relations at the micro level. Each method is applicable under certain conditions and in certain areas of social relations. To study the macro-processes of the invisible economy, the monetary method, the methods based on discrepancies between different statistical data, the method of technological coefficients, the assessment by employment indicator, etc. are used.
This study does not set the task of a detailed analysis of all methods developed by modern science for measuring the shadow component of the economy. In the authors' opinion, it is important to identify the main methods that may be applied at the regional level. Studying the dynamics and regional features of the shadow economy is important for economic development and the formation of a sustainable state policy at both regional and state levels. It should be noted that the quantitative assessment of the shadow economy at the regional level is much less common. Often, scholars describe the characteristic features of the informal economic activity in the regions and the degree of its influence on certain aspects and spheres of society.

Materials and Methods
Not all macro methods for measuring the shadow economy can be suitable for identifying the volume of the regional shadow economy. This is due to the specific features of the constituent entities of the Russian Federation, and problems with the availability of certain statistical data in the regions.
The main method for identifying the state of the shadow economy in the Russian Federation in the context of its regions was the method of Fedotov, Nevzorova, and Orlova. According to this methodology, the shadow activity is the only component of the gross regional product, therefore it can be included in the gross profit of the economy and gross mixed income. A significant advantage of the methodology is the use of data from the Federal State Statistics Service (Rosstat) and the Federal Tax Service [22; 23].
The size of the invisible component in the official economy of each region is determined as the discrepancy between the national accounts data, which are presented by the official statistics, and the indicators of tax reporting. This methodology was used to analyze the regional state of the shadow economy in Russia for the period of 2007-2018.
In general terms, the calculation of the size of the regional shadow economy was carried out according to the following formula: where GRP SE -the share of the shadow economy in the region's GRP, %; PR TB -legal profit included in the tax base for corporate income tax.
Tax reporting data are more reliable; to identify legal profit, the size of the tax base for where OR -official remuneration of employees (excluding its hidden component), TP -net taxes on production (corporate property tax, transport tax and land tax paid by legal entities, license fees), PR ST -profit reflected in the statistical reporting of organizations [22].
The results of assessing the state of the regional shadow economy in terms of tax and statistical discrepancies are not significantly different from each other.

Results
In Russia, which is divided into regions, centrifugal tendencies largely contribute to the development of informal processes and make it difficult to legalize them. In modern conditions, it is very difficult for the federal center to regulate economic activity in the regions; therefore, for the purpose of effective government regulation, it is very important to assess the state of its shadow component.

Discussion
Regions of Russia differ from each other in size, population, natural resources, and features of economic development. Institutional changes taking place in Russia at the turn of the century led to the formation of a special model of shadow economic activity.
An analysis of the state of the shadow economy showed the unevenness of its development in different regions of the country.
Regional features of the shadow economy have significant structural differences and are determined by: • geographical location; • resource potential and possibilities of its use; • general economic condition of the region; • sectoral structure and general specialization of the region's economy; • social structure of the region, its traditions, and the specific archetype formed on their basis in relation to shadow activity.
The increase in the scale of the shadow economy in most regions of the Russian Federation since 2009 can be explained by a number of factors: 1. A sharp increase in uncertainty in the political and economic spheres, which significantly affects the decision-making of economic agents. In such conditions, they reduce consumption in the current period, so that, according to the theory of permanent income, it would be possible to smooth out possible fluctuations in income and consumption in the future, increasing savings [24]. In such conditions, legal capital is "hiding in the shadows", and there is an increase in capital outflow abroad. 3. The state/regional regulation of the socio-economic sphere is of great importance for the development of the shadow component. Continuous changes in rules and laws, an unbearable tax burden, unavailable loans and excessive involvement of the authorities in business are just some of the problems in the economic sphere that an entrepreneur faces. 4. Corruption continues to be the main reason for the growth of the shadow economy. As part of this research, it was revealed that, when assessing the level of corruption, the opinions of Russians and experts were almost identical: 49.5% of the surveyed citizens and 47.5% of experts consider the level of corruption in modern Russian society to be high; 44.8% and 44.5%, respectively, assess the level of corruption as average, 5.7% and 8% -as low [27].

Habitualization of informal behavioral practices is a situation when informal rules
5. The gap between the interests of society and the ruling elite is caused by its isolation.
Integrating into the system of public administration, individual representatives are actively implementing shadow strategies in the direction of "business takeover" and/or "state takeover".

Conclusion
The obtained results on the assessment of the shadow economy of the constituent entities of the Russian Federation make it possible to identify the scale and trends in the development of the shadow activity in the regions, to predict its change and prospects.
The position of rejection and intense struggle against all manifestations of the shadow economy, actively declared by the authorities and business, does not diminish the urgency of the problem of the spread of hidden economic processes throughout the territory of the Russian Federation and its penetration into all spheres of society. At the same time, the current nature of the impact on shadow processes seems to be aspectual, unsystematic, and focused mainly on the identification of already occurred economic offenses or elimination of their negative consequences, compensation for harm, and creation of formal anti-corruption departments or structural units.
The presence of the shadow economy in all Russian regions poses a threat not only to the economic security of a particular territory but also to the safe and sustainable development of the entire country. Certain measures developed within the framework of state policy in the field of taxation, finance, education, migration, support of entrepreneurship have become a significant achievement in the countering of shadow processes; however, they did not put an end to it, because the desire to maximize and optimize profits, and sometimes even survive in a harsh market environment gives rise to new forms and ways of conducting shadow economic activities.
