This article is aimed at analyzing the construction cluster of the Samara region economic relations. The subject of this research are key construction organizations and manufacturers of building materials, products and structures and their industrial and economic relations. A survey of regional building materials manufacturers, products and structures, research of scientific works, regulatory legal acts and materials of discussion platforms related to sources of information on the development of the construction industry in the country and the region made it possible to identify the main factors affecting the production and economic activities of building materials manufacturers. The authors developed a mathematical model that allows evaluating the dependence of the production indices of building materials on the inflation rate, the materials most susceptible to this phenomenon have been identified. Regression models were obtained to identify dependencies of output volumes on factors affecting the production and economic activities of building materials industry enterprises, the analysis of the obtained equations is carried out. Based on the available observations on these indicators over a period of 7 years, a variance analysis of the samples was carried out on a monthly basis and regression models of their changes monthly and by year were constructed, the significance and adequacy of the constructed models for 23 types of building materials were estimated. Using the obtained regression dependencies, the studied parameters were extrapolated for the period until 2024, and indicators with a decreasing tendency were identified. Statistical calculations and their analysis were performed in MS Excel and Gretl. |
