This article examines the
relationship between the goals and indicators of sustainable development at
various levels of regional socio-economic systems. Various approaches to the
assessment of sustainable development were analysed. To assess the impact of a
company’s activities in the social, environmental and economic spheres on the
sustainable development of the region, a traditional econometric analysis was
carried out using panel data. A set of socio-economic indicators was used to
build an econometric model that evaluates the relationship between various
elements at different levels of management. The indicator of life expectancy in
the region was chosen as the final variable, as it reflects the totality of
factors affecting the standard of living of the population. Based on an
econometric analysis of interdependence, the indicators that can have an impact
on the development of the region were identified. These indicators include the
level of gross domestic product (GDP), the average salary in the enterprise,
the costs of environmental protection, the levels of emissions produced by the
company and the number of employees who have received higher education. In the
course of the study, the authors confirmed the influence of a company’s
activities in the social, environmental and economic spheres on certain aspects
of sustainable development in the Russian Federation.

Issues
related to sustainable development (SD) have become relevant in the past
several decades. The idea of SD is consistent with the global nature of
society’s problems, and many states and their constituents use it to develop
effective strategies for managing socioeconomic systems (Abed & Yakhlef, 2020). Today, over a
hundred countries, especially well-developed ones, make decisions consistent
with the concept of SD at the government level. In order to outline an
effective strategy, countries should consider an integrated approach to
ensuring and maintaining SD at all levels of the economy: both at the country
level and at the level of the region, enterprise, etc. Moreover, it is
necessary to accommodate the interests of all stakeholders (population,
enterprises, regional government, etc.) in order to achieve the environmental,
social and economic aspects of SD goals (SDG). If enterprises fail to
participate or are not interested in implementing this concept, SD cannot be
achieved in the region (territory) or in the country as a whole.
One of the most important indicators of regional development is the life expectancy of the population (Shaporova & Tsvettsykh, 2020). This is a complex indicator that reflects a number of factors affecting the living conditions of citizens. For enterprises, life expectancy in the republic can be influenced by reducing pollutant emissions into the environment. Another way to improve the duration, standard and quality of living is to provide social guarantees and payments to company personnel as well as maintaining high wage levels (Oláh et al., 2018). The level of education and skills of a company’s personnel in its operating territory indicate the educational level in the region. Companies’ assistance agreements with other organisations impact on the development of partnerships both within the republic and outside its limits. Thus, any activity of large companies in the region invariably affects the living conditions in the region and its sustainable development. In this regard, a question arises: ‘What impacts do various company activities in the social, ecological and economic spheres have on SD in the region, and how can we evaluate them?” Therefore, the purpose of this work is to assess the impact of company operations in general on the SD of the region.
The idea of SD implies that economic, ecological
and social spheres of life are interacting (Brazovskaia
et al., 2021; Berawi, 2019). Consequently,
if any of these spheres are influenced, the impact on all life domains must be
considered. Also, it should be noted that some works are dedicated to studying
the methodology that is used for assessing the SD of socioeconomic systems (Malagueño et al., 2018). Therefore, there is a
need in the academic community to study the impact of companies’ activities on
certain aspects of SD in their regions.
To
monitor the progress toward SDG 3 (Ensuring a healthy lifestyle and promoting
well-being for all at any age), the World Health Organisation (WHO) has
reviewed several comprehensive indicators, including ‘life expectancy’,
‘healthy life expectancy’ and ‘number of deaths under the age of 70’. These
indicators show not only progress in achieving the goals included in SDG 3 but
also progress in achieving other health-related goals. Guzel
et al. (2021) argued
that achieving a healthier society and increasing life expectancy is the basis
for progress in SDGs 3 and 17. However, this is not possible without economic,
social and political integration between governments, companies and societies. Dietz and Jorgenson (2014) drew attention to the
fact that one of the key development goals of countries is increasing life
expectancy, which, in turn, depends on the well-being of citizens and the
amount of harmful emissions. Dalevska et al. (2019)
presented a methodological approach for comprehensively assessing the
socio-economic parameters of countries’ SD based on the current UN information
base. They propose an assessment of the degree of development of international
trade and investment relations, the level of life expectancy, the standard of
living and the prosperity of international entities under the influence of
sources of economic growth. Özgür et al. (2021)
explored the relationship between various indicators of SD and the size of the
informal economy. The authors included life expectancy in the group of
variables associated with the level of health of the population. As a result,
the authors found that the size of the informal economy
sector
is negatively related to the life expectancy of the population.
Concluding
the literature review, we can say that life expectancy is a frequently used
indicator for assessing the SD of countries and regions. At the same time,
however, existing studies do not assess how the activities of individual
companies affect the regions and their SD through indicators such as life
expectancy.
The
different regional and company indicators can be used to study the dynamics of
socioeconomic development of a region. Also, they can be used as the basis for
building econometric models that assess interrelations between various elements
of the socio-economic system at different levels of management. The goal of the
econometric model, in this case, is to confirm the significance of
cause-and-effect relationships and to verify the hypothesis about the influence
companies’ activities have in the social, ecological and economic spheres on
individual SD aspects of the region as a whole.
Establishing
the relationship between the indicators of the region and the company with only
one example object does not make it possible to extend the findings to other
similar objects. Accordingly, the authors decided to study a number of regions
that differ in many ways, but all have large enterprises that could have a
significant impact on regional development. Hence, a data panel was formed,
including 10 Russian regions and the 10 largest companies in various industries
for the period from 2009 to 2018. These regions were selected based on the
presence of a large enterprise (company) that makes a significant contribution
to the economy of the region. The data contain statistics about the same
objects for a series of subsequent time periods. From the perspective of
regression analysis, using these data increases the volume of the sample that
is considered and makes the assessment parameters of the regression model more
effective. Moreover, using the panel compensates for many negative aspects of
applying only spatial or time data (Clark et al.,
2020). In this case, no information is lost, unlike the first case,
where it is lost because the development dynamics of the objects are not fully
considered, and the second case, in which the heterogeneity of the objects
themselves cannot be considered at all (Lutsenko,
2018). We analyse panel data using the following modelling approaches:
1.
Pooled data regression. The parameters of the model (m+1) are assessed using
the least squares (OLS) method by all nt observations. It makes sense to use
this method if it is assumed that there are no heterogenic characteristics of
the observation objects or time points. Otherwise, the prerequisites of the OLS
regarding the residual sums are violated.
2.
Fixed effects models. These models imply that each of the studied spatial
objects has individual non-observed effects. Using this model makes it possible
to control the bias of the estimates caused by individual effects of the
objects.
3.
Random effects models. Differently from fixed effects models, random effect
models expect that even though the distinctions between spatial objects exist,
they are random.
In
the first stage of the regression analysis, factors that could influence the
dependent variable are determined. In this study, the hypothesis suggests the
presence of considerable cause-and-effect relationships between the company’s
SD indicators and the indicators showing the level of SD in the region. The
life expectancy of the region’s population was chosen as the dependent
variable. According to the methodology used to calculate this indicator (Toson & Baker, 2003), life expectancy
reflects the total influence of the social, economic and ecological factors on
the living standard and can be an important measure of the socioeconomic
development of territories, as an increase in the living standard of the
region’s population is the main strategic goal of regional authorities. In the
second stage, indicators of the companies were selected that, according to the
hypothesis, could reflect the influence of the company on the social, economic,
and ecological circumstances in the region.
The
regression analysis of the data was carried out using the Stata package. In the
first stage, a correlation analysis was conducted for the chosen indicators to
assess the presence and directions of the relationships. Then, different
variations of the models were built, and each was tested to meet the principles
of the Gauss–Markov theorem. Finally, a model with the best characteristics
based on the totality of the conducted tests was selected. In order to verify
the hypothesis about the interrelationship between the company’s activities in
the social, ecological and economic spheres and the SD of the region,
traditional econometric analysis was carried out using panel data.
For
these variables, statistics were collected for the period from 2009 to 2018 for
the 10 regions and 10 regional companies, respectively. The following regions
were chosen for the study: the Republic of Sakha (Yakutia) – Public Joint Stock
Company (PJSC) ‘ALROSA’; Murmansk Region: PJSC ‘MMC Norilsk Nickel’; Leningrad
Region: PJSC ‘Sovcomflot’; Tumen Region: JSC ‘Transneft Siberia’; Vologda
Region: Public company ‘Severstal’; Sverdlovsk Region: PJSC ‘T Plus’; Perm
Krai: EuroChem plc.; Krasnoyarsk Krai: PJSC ‘MMC Norilsk Nickel’; Nenets
Autonomous District: JSC ‘Zarubezhneft’; Yamalo–Nenets Autonomous District:
OJSC ‘Novatek’. Large enterprises that develop corporate SD strategies and
provide open data are based in these regions.
The
life expectancy in the region was selected as a final variable, as it reflects
a totality of factors affecting the living standard of the population. In the
course of the analysis, an attempt was made to reveal the dependence of life
expectancy on such indicators as gross regional product, unemployment rate,
average salary in the large enterprise in the region, current environmental
costs of this enterprise, number of jobs given to the population, ??2 emissions
of the company, tax payments made by the enterprise to the regional budget, the
number of licenses and patents of the company, the share of the company in the
sector and the share of employees with higher education in the enterprise. In
the analysis, we assumed that the selected company indicators would have the
largest influence development level of the region. Table 1 lists the selected
variables.

The
econometric analysis of the panel data was performed using the STATA package.
The preliminary analysis in this research involved studying a correlation matrix (Table 2). It can be concluded from this correlation matrix that life expectancy (OPZ) has a weak correlation with the majority of the indicators, except for GRP. Then, we proceeded to the next stage, which involved conducting a regression analysis (Table 3) on the combined data.

In
general, the model produced is significant (F(10,89)=6.16; Prob>F=0.0000).
The coefficient of determination is 0.41, while the corrected coefficient of
determination is 0.34, which means that the dispersion of the selected
indicators explains only a slight share of the OPZ dispersion, and the
specification of the model should be verified. Only two coefficients of the
equation are significant (GRP and RabVO). The model obtained is not of high
quality.
Figure 1 (a) Graph of Student-t residuals plus leverage; (b) Augmented partial residual graphs for linearity analysis
In
order to determine the causes of the poor quality of the model, diagnostics
were performed. An outlier analysis of the model was conducted using Student-t
residuals and leverage in the first stage of the diagnostic (Figure 1 a, b). No
outliers were found. In addition, a dfbeta test was performed for all
variables, which did not reveal influential observations capable of displacing
the coefficients of the analysed variables. Then the linearity of the relation
between the selected factor variables and the dependent variable was verified.
The
linearity test revealed non-linear relationships between some variables and the
endogenous variable (Figure 2). Thus, it was decided to transform some
variables into logarithmical form to achieve greater linearity. The selection
of the correct functional form helped to improve the initial model
significantly (Table 4).

In
general, the model produced is significant (F(10;89)=19,44;
Prob>F=0.0000). The coefficient of determination is now 0.686, while the
corrected coefficient of determination is 0.651. This increase in the
determination coefficient can be seen in Table 3. The significance of the
factor variable coefficients improved. The next step involved analysing this
model for factor multicollinearity. The VIF (variance inflation factor) test
did not show substantial collinearity between the factor variables. However,
the analysis of the correlation matrix revealed substantial relationships
between the current environmental costs of the enterprise and the tax payments
made by the company to the regional budget as well as between the number of
jobs given by the company to the population of the region and CO2 emissions. Moreover,
some variable coefficients are not significant. Due to this, the specification
of the model was corrected. A more favourable econometric model was obtained
through several iterations (Table 3). The final model is significant
(F(5;94)=32.59; Prob>F=0.0000). The coefficient of determination is now
0.634, while the corrected coefficient of determination is 0.615. The following
variables remained in the final model: GRP, average salary, environmental
costs, CO2 emission levels and the share of personnel with tertiary education.
Since
multicollinearity and non-linearity were excluded from this model, it was
necessary to test the specification and residuals of the model. In order to
verify the specification of the model, the Ramsey omitted variable test (OV
test) and linktest were performed. While the corrected R2 is somewhat lower
than R2, which could be evidence of problems with the specification, according
to the results of the OV test, there are no omissions in the model (OV-test:
F(3;91)=0.28; Prob>F=0.8379). In order to confirm these results, a linktest
was run, which showed problems with the specification. The results indicated
problems with the specification of the model and the presence of omitted
variables. However, this was assumed from the beginning, as the lack of a
comprehensive statistical database for enterprises and regions did not allow us
to include in the analysis all the necessary variables that emerged from the
literature review. Next, we tested for normal distribution and homoscedasticity
of the residuals (Figure 2).
Figure
2 Graphic tests for normal distribution of the
residuals of the model (a) and graphic test for heteroscedasticity (b)
The
graphs obtained demonstrate that the distribution of the residuals of the model
is close to normal (a slight deviation from normality in the right tail). For
heteroscedasticity testing, the graphical test (Figures 8b) and the
Breusch–Pagan (chi2=6.44; Prob> chi2=0.0112) test were performed, showing
weak heteroscedasticity of the residuals. Some heteroscedasticity is
characteristic of real economic data. It means that the obtained estimations of
the coefficients of the model equation will all be
non-displaced and linear, but their effectiveness is questionable. However,
this insignificant heteroscedasticity can be ignored, as it does not substantially
distort the analysis results. Using econometric
analysis, we obtained a model of the dependence of the final variable from the
factor variables. The function of the simple linear regression model takes the
following form (formula 1):
where
I =1..10 is the number of the region, t=1…10 is the studied year, and v is the
random error.
In
order to determine the final form of the regression model, models with fixed
and random effects were constructed. Using the Wald test, the Breusch–Pagan
test and the Durbin–Wu–Hausman test, the three types of models were compared to
each other. The results showed that the linear regression model with pooled
data was the best model for this research. Thus, the analysis revealed the most
significant corporate-level indicators that can impact life expectancy in the
region. The indicator ‘GRP’ does not refer directly to the results of a
particular company. However, its value is formed as a result of the activities
of enterprises in the region. Thus, if the GRP grows by 1%, life expectancy
will increase by 0.0224 years, all other things being equal. If the average
salary grows by 1 dollar, life expectancy will increase by 0.001 years. If the
environmental costs increase by 1%, life expectancy will grow by 0.006 years.
If the number of employees with tertiary education increases by 1%, life
expectancy will increase by 0.17 years. A 1% growth in CO2 emissions
will reduce life expectancy by 0.0062 years. Thus, the growth of all indicators
except enterprise CO2 emissions contributes to an increase in life
expectancy. Regarding the abovementioned factors, companies can influence the
level of SD both at the corporate and regional levels.
This
study proposes observing the SD of territorial systems based on the influence
of factors at the corporate level. The influence of some macro-level factors
has already been considered, for example, GRP
(Rotova, 2020) and CO2 emission levels (Jafrin et al., 2021). At the same time, some
factors were identified through which companies can influence the SD of
territories. For example, in this study, the factor ‘average salary in the
enterprise’ was considered; previously, scientists considered ‘income level’ as
a factor reflecting the wealth of people (Hill et
al., 2019). Since the level of emissions is typically considered a
factor influencing the environmental aspect of SD, the factor ‘current
environmental costs of an enterprise’, which was included in the final model in
this study, shows that the environmental situation in the region can be
influenced by the amount of money spent by large companies in the region on
environmental protection activities. Education as an influencing factor on life
expectancy in the region and, consequently, on its SD, was considered mainly
based on the level of education of the population of the whole country. The
authors considered the extent to which increased life expectancy is associated
with structural changes in the population caused by an increase in the level of
education (Luy et al., 2019). The
significant factor ‘proportion of employees with higher education in the
enterprise’ identified in our study allows us to consider the impact of the
level of education on life expectancy at the corporate level.
The authors studied the relationship between the regional and
corporate level of economic management and identified the main indicators that
reflect the impact of a company’s activities on the SD of the region in which
it operates. As an indicator of the SD of the region, life expectancy was
chosen as an indicator that equally depends on all three parameters (economic,
social and environmental). By influencing the indicators included in the model,
it is possible to increase the level of SD of the region. Econometric analysis
of this relationship helped to identify the indicators that have the greatest
impact on the development of the region, expressed in this study as life
expectancy. These indicators include the level of GRP, average wages in the
enterprise, environmental protection costs, emissions levels and the number of
personnel with higher education. By influencing these factors, companies can
impact the level of SD at both the corporate and regional levels. The results
of this study show that when forming a strategy to achieve SD in individual
territorial systems, the corporate factor should not be overlooked. The
activities of large companies that affect the region in all three ways
(economic, social and environmental parameters) should also be reformed. This
study provides a basis for governing authorities to make progress in achieving
the SDGs at the corporate level.
