The depletion of traditional organic energy sources and aggravated environmental problems are the reasons why the level of energy efficiency is an important factor in the competitiveness of the national economy. Russia ranks third in the world in terms of total energy consumption and its economy is distinguished by a high level of energy intensity (amount of energy per unit of GDP). In 2019, this figure was 9.62 tons of oil equivalent (toe) per 1 million rubles, which is 40% higher than the world average.
The low energy efficiency of the Russian economy is a widely recognized problem. A special decree of the Government of Russia in 2018 sets the task of increasing the level of energy efficiency of the Russian economy by 23% by 2030. One of the ways to solve this problem is the development of nuclear energy, and increasing the competitiveness of nuclear energy is one of the key issues for the national economy. In this connection, solving the problem of assessing the competitiveness of the nuclear industry and its leading companies occupies a key place among the practical scientific problems, the solution of which is facilitated by the results presented by the authors in this article.
Rosenergoatom Concern JSC is the leading energy generating company in the Russian nuclear industry. The results of the study of the competitiveness of Rosenergoatom Concern JSC were obtained on the basis of the authors’ methodology for assessing the competitiveness of an energy generating company. The novelty of the presented methodology lies in the developed normative and evaluative model and the coefficients of competitiveness of an energy generating company.
The advantages of the authors’ model are that it allows (1) obtaining integral assessments of the competitiveness of a power generating company at short time intervals for a large number of indicators and (2) quantitatively measuring the effects of different factors on the competitiveness of a power generating company, provided that the grouping of indicators of competitiveness of a power generating company is justified by influencing factors. The two factors considered by the authors were: the general market factor and the industry factor.
According to the results of the study, it was found that Rosenergoatom Concern JSC demonstrates positive increase of the competitiveness indicator mainly due to the industry factor. With this regard, it was concluded that, within the framework of state policy, it is advisable to strengthen support for the Russian nuclear industry by creating additional conditions and opportunities for its energy generating companies on the domestic energy market.
Competitiveness, energy generating company, normative and evaluative model
Russia is one of the leaders on the world energy market utilizing different forms of energy generation. One of the main forms is nuclear power generation producing about 20% of electric power in the general energy balance of the country. At present in Russia 38 nuclear power units are in operation in Russia on 11 NPPs. Contribution of nuclear power generation is important in the European part of Russia and, especially, in the northwest where power generation by NPPs reaches 42% (
The objective of the present study is to perform dynamic assessment of competitiveness of Rosenergoatom Concern JSC on the domestic market. This objective is achieved using statistical factor methods, dynamics analysis, dynamic normal, which allowed applying both conventional and newly introduced indicators of competitiveness of a business entity reflecting industry specifics of Rosenergoatom Concern JSC.
Competitiveness of an energy generating company is the ability of the company to use both its own and natural resources with higher efficiency ensuring more beneficial competitive positions.
Normative and evaluative model of competitiveness of energy generating company was developed of the basis of the concept of the system of balanced indicators and the dynamic normal method for conducting diagnostics of competitiveness of Rosenergoatom Concern JSC.
The systems and models of indicators as the instruments for assessment of competitiveness and results of operations of business entities are in application already for almost 100 years. One of the first attempts was the Dupont model (1920), which found widespread application by large corporations. Tableau de bord model is applied in Frenchspeaking countries in the analysis of company management since 1932. Prominent scientists R. Kaplan and D. Norton (
Dynamic normal method became the new approach to the assessment of enterprise management in a stateplanned economy. The method for the first time treated the enterprise as the economic system including not only material and technical assets, but the management system as well. The basis of the dynamic normal method is the procedure of selection of economic indicators and their systematization. The idea of systematization of dynamic indicators for economic systems belongs to I.M. Syroezhkin (
The list of indicators (dynamic normal) structured according to the growth rates (indices) was defined for constructing the model. Correlations between basic indicators (structuring principles) are shaped on the basis of coefficients characterizing competitiveness of an energy generating company suggested by the authors. The assessment demonstrating the fraction of realized correlations between the rates (indices) of growth of factual values of dynamic normal indicators in the normative and evaluative model of competitiveness of the energy generating company is the integral indicator of competitiveness 22]. The obtained value of the integral characteristic is found within the interval [0, 1]. The closer is the value of the integral estimation to unity the higher is the level of competitiveness of the energy generating company.
The following indicators are included in the dynamic normal.
The above dynamic normal indicators are divided into two groups as follows: universal indicators (applicable in the analysis of competitiveness of any company) and unique indicators (can be applied only in the examination of competitiveness of energy generating companies), which allows quantitative measurement of the effects of the conventional (general market) factor and the industry factor taken separately on the competitiveness of the energy generating company (Fig.

The normative and evaluative model is formalized as the E = {e_{ij}}_{n}_{×}_{n}, where n is the number of indicators in the dynamic normal; in our case this number is equal to eight (See Column 2 in Table
${e}_{ij}=\left\{\begin{array}{l}1,\text{if}Tp\left({\Pi}_{i}\right)Tp\left({\Pi}_{j}\right)\\ 1,\text{if}Tp\left({\Pi}_{i}\right)Tp\left({\Pi}_{j}\right)\\ 0,\text{if there is no correlation between the indicators}\end{array}\right)$ , (1)
where i, j are the numbers of indicators in the dynamic normal; П_{i}, П_{j} are the indicators with ith and jth numbers in the dynamic normal, respectively; Тp (П_{i}) > Тp (П_{j}) и Тp (П_{i}) < Тp (П_{j}) are the standard correlations between the rates of growth of the indicators of the dynamic normal.
The matrix Е after the exposure of additional correlations on the basis of the transitivity principle becomes the normative and evaluative model (Table
The formula for calculating the quantitative level of the integral estimation У has the following form:
$Y=\frac{{\sum}_{i=1}^{n}{\sum}_{j=1}^{n}{b}_{ij}}{{\sum}_{i=1}^{n}{\sum}_{j=1}^{n}\left{e}_{ij}\right}$ , (2)
where
${e}_{ij}=\left\{\begin{array}{l}1,\text{if}\left({e}_{ij}=1\text{and}{f}_{ij}\ge 0\right)\\ AND\left({e}_{ij}=1\text{and}{f}_{ij}\le 0\right)\\ 0,\text{in other cases}\end{array}\right)$ . (3)
In the above expressions b_{ij} is the element of the matrix of coincidences of the factual and the standard growth rates В = {b_{ij}}_{n}_{×}_{n}; е_{ij} is the element of the matrix of the normative and evaluating model (1); f_{ij} is the element of the matrix of factual correlations F = {f_{ij}}_{n}_{×}_{n}:
${f}_{ij}=\left\{\begin{array}{l}1,\text{if}Tp\left({\Pi}_{i}\right)Tp\left({\Pi}_{j}\right)\\ 1,\text{if}Tp\left({\Pi}_{i}\right)Tp\left({\Pi}_{j}\right)\\ 0,\text{if}Tp\left({\Pi}_{i}\right)=Tp\left({\Pi}_{j}\right)\end{array}\right)$ , (4)
where Тp (П_{i}), Тp (П_{j}) are the factual growth rates for the ith and jth indicators of the dynamic normal, respectively.
Effects from each of the indicators on the growth of the estimation is determined according to the following formula:
$\Delta Y\left({\Pi}_{i}\right)=\frac{{\sum}_{j=1}^{n}{b}_{ij}^{o}{\sum}_{j=1}^{n}{b}_{ij}^{o}}{{\sum}_{i=1}^{n}{\sum}_{j=1}^{n}\left{e}_{ij}\right}$, (5)
where ΔУ (П_{i}) is the increment of growth of the integral estimation caused by the dynamics of correlations of growth rates between the ith indicator and the remaining indicators; b^{о}_{ij}, b^{б}_{ij} are the elements of the matrix of coincidences of the factual and the standard correlations between the growth rates of indicators for the reporting and the base periods, respectively. Application of the suggested methodology is discussed in more details in (
