Does Working in a Cluster Provide Higher Productivity to Industrial Enterprises in Russia?

— Despite the fact that economic clusters are a relevant topic in the world research literature, the specifics of their development in countries with a former planned economy have not been sufficiently studied. The article examines the effect of industrial enterprises working as part of a cluster in Russia. The main research method is regression analysis of the production function with a binary variable cluster. The objects of study are the industrial enterprises of 15 clusters in Russia that received support from government programs. The reference group included enterprises similar in specialization and number of employees to the enterprises of the study group, located in Russian regions without clusters. In total, we collected data on the activity of 695 enterprises for 2016–2020. Calculations showed a negative relationship between the cluster variable and the revenue of enterprises; however, this relationship is small in scale.
