The influence of fixed assets on the gross regional product in the digital economy: an econometric analysis

In the digital economy, approaches to assessing all spheres of economic life are changing. Regions strive to increase the gross regional product, which is a characteristic of their successful not only economic, but also social development. The gross regional product is influenced by physical, human and financial capital. Fixed capital, as part of real capital, serves as the basis for organizing the functioning of economic agents. Fixed assets in the digital economy should ensure the digital transformation of both companies producing goods and services and social facilities. Otherwise, the region is among those lagging behind in all parameters of life. Accordingly, it influences the performance of companies and, as a consequence, the formation of the gross regional product. The purpose of this study is to determine the impact on the gross regional product of the availability and commissioning of fixed assets of the city of Sevastopol based on the use of economic and mathematical tools in the digital economy. The authors propose a methodology based on linear regression, a class of production functions, the Cobb-Douglas function. Using retrospective data, the authors determined that during the periods under study, the commissioning of new production capacities in the region turned out to be insignificant in comparison with the current level of fixed assets and does not significantly affect the gross regional product. Further research by the authors will be aimed at determining such a level of newly introduced fixed assets, which will ensure the growth of the gross regional product.
