The article is devoted to the study of the interaction of the construction cluster participants, which determines the dynamics of the volumes and paces of construction in the region. The main subjects of this process are construction organizations and manufacturers of building materials. The main requirements of regional construction companies to suppliers of building materials are defined. The factors are revealed reflecting the dependence of the results of the construction companies'

... s on the production and economic activities of the companies producing construction materials. Based on the available observations for 7 years, a statistical analysis of the samples was carried out and regression models of dynamics were constructed, the significance and adequacy of the obtained models were checked. The constructed mathematical models reflect the dependence of the volume of performed work in construction from the production indicators of manufacturers of building materials and supply organizations. The conducted research allows us to conclude that the most significant negative factors affecting the volume of work performed are the dynamics of prices for finished metal products and the dynamics of prices for the transmission and distribution of electricity.
