In the context of the theory of entrepreneurial ecosystems (EE), a set of administrative and legal measures that stimulate the development of entrepreneurship in agriculture have been identified and analyzed. These elements of EE are poorly studied in science, at the same time, administrative and legal measures to stimulate entrepreneurship in agriculture are positioned from the point of view of the development of the institution of state regulation in agriculture and can have a significant impact on all structural elements of EE. The authors have identified three models of state regulation of entrepreneurship in agriculture, one of which is the model of state stimulation of entrepreneurship in agriculture. State and non-state measures to stimulate entrepreneurship in agriculture are highlighted, the forms and levels of regulation are indicated in state regulation. The quantitative and qualitative growth of rural entrepreneurship subjects, the introduction of innovations, the formation of entrepreneurial values, the potential for solving modern problems of agricultural entrepreneurship are highlighted as the goals of state stimulation of entrepreneurship in agriculture. It is concluded that it is possible to single out an agricultural entrepreneurial ecosystem (AEE).
