SUMMARY
The purpose of this study is determining the optimal proportions of interaction between foreign and domestic suppliers and investors in the institutional structure of the VTGI. Based on a survey of representatives of 388 VTGI enterprises, the economic efficiency of the industry's enterprises and the degree of dependence on foreign suppliers and investors are assessed. The survey was conducted in a stable market environment (April-June 2019) and in a crisis (April-June 2020). Regression models of the influence of indicators of dependence on foreign suppliers and investors on the enterprise performance indicator are constructed. By solving a system of equations (dependence functions), the optimal proportions of the structure of interaction between foreign and domestic suppliers and investors are determined quantitatively in order to maximize the economic efficiency of clothing and textile enterprises in the context of crisis manifestations in the market conditions of operation
