The article presents the implementation of the results of supporting sectoral entrepreneurship in rural areas as a multifunctional and multi-channel process of formation, attraction, and use of financial resources provided by the rules of the institutional environment of state policy.

It determines the hypothetical ability of the multifactorial system of the institutional environment of state policy to influence the level of financial capacity of sectoral enterprises, taking into account the tax burden and targeted use of state financial resources for production, processing, and storage of agricultural products as well as to update the technological process
