The necessity of developing and forming a system of state regulation of the agro-industrial complex on the basis of the Inno-diversification approach is methodically substantiated. The term Inno-diversification has been introduced into scientific circulation, which characterizes the penetration of novelties (innovations) into new areas (diversification), which gives a synergistic effect as a result of their combination. An Innodiversification approach is proposed as a complex of innovative,

... rsification and synergetic approaches, the combination of which strengthens their advantages and compensates for their disadvantages. The Inno-diversification approach involves a targeted change in the functioning of an organization as a single management object, a combination of original research methodologies with specific organizational forms of their conduct and a set of principles, the basis of which is the consideration of objects as self-organizing systems. Based on a morphological analysis of various sources of information, a system for the development of organizations of the agro-industrial complex was proposed, which is a closed system consisting of four main elements: causes, aims, functions and principles of state regulation of the agro-industrial complex. The essential structure of the functioning system is a chain, the first link of which is the sphere of agriculture, the secondof industry and the last oneof services. It is proposed to consider the essential model of the digitalization system of state regulation of the dairy industry as a closed system consisting of three elements: state regulation, digitalization and parameters of the industry itself. The novelty of the author's proposals are: inno-diversification approach, the development system of organizations, the essential structure of the functioning system, the essential model of the digitalization system of state regulation of the dairy industry.
