Analysis of statistics at the micro-level shows that the development trends of a large number of resident entrepreneurial structures of industrial parks are characterised by adverse dynamics. Accordingly, assessment of the performance of entrepreneurial structures and improvement of their management models in the general system of industrial parks become more relevant. This paper presents a methodological approach to the construction of a spatial-rating assessment of the performance of entrepreneurial structures in the system of industrial parks functioning. As a result, two groups of Russian regions were identified, among which a potential resident, when making a decision on the placement of production facilities, can choose a region taking into account its investment attractiveness and industrial activity. Two discriminant groups of industrial parks were determined, the condition of which can be defined as economically inefficient and efficient, by evaluating parks with low and high values of the park rating level in terms of attractiveness for external investors and resident entrepreneurial structures. The proposed methodological approach can be applied to improve the quality of decisions on the formation of differentiated strategies for sustainable development of both individual entrepreneurial structures in the system of industrial parks and their clusters, and regions as a whole. It is recommended for both enterprises and industrial parks when making decisions on the formation of strategies and development scenarios, as well as for federal and regional authorities when designing documents for the territorial development on the strategic and tactical level.

The need to study the development of business entities in the context of individual categories of industrial parks is connected with different concepts of their development and territorial expansion. The suggested methodological approach to assessment of sustainability level of the business firms functioning in the system of industrial parks includes the following main stages: grouping of industrial parks and the selection of representatives of the groups; rating assessment of stability level of firms functioning in the system of industrial parks; grouping of businesses by the level of sustainability. The technique was tested on data from 150 industrial parks. The results of the implementation of the suggested approach show that more vulnerable positions are typical of businesses operating as part of industrial parks as “greenfield” companies. At the same time, the highest proportion of businesses with a low stability level is typical of developing parks, which indicates the need to expand the range of incentives for these businesses. The most stable cluster of entrepreneurs is business entities of developing parks such as “brownfield” companies. Entrepreneurs operating within developed parks as “brownfield” firms are characterized by a satisfactory level of sustainability. The proportion of entrepreneurial structures with a low stability level remains quite high, which indicates the need to adapt the development strategy of business entities in the system of such structures. The results obtained made it possible to identify the most vulnerable groups to risks, business entities and can be used to form a strategy for their sustainable development in the system of industrial parks.
