One of the priority strategic objectives aimed at reducing the unjustifiably high spatial differentiation of rural areas is their diversification, carried out by involving unused resource reserves into development, creating new opportunities for the industries which products have a steady market demand. The purpose of this scientific work is to justify the need to move from a predominantly mono-functional to a diversified model of rural development. Creating models for their diversified development requires defining the rural areas as a special space, in which a specific activity closely related to the natural habitat is carried out, depending on the natural, economic factors of farming and formed in the conditions of the almost universal distribution of multi-component agricultural production. In the process of research, the relationship between the diversity of the rural economy structure and the multifunctionality of rural areas was revealed, which showed the need to diversify the economy by stimulating various types of activities. Taking into account domestic and foreign experience, approaches to building a model of diversified development of rural areas are justified. Based on a study of the rural economy structure, a model of diversification was proposed, containing single-industry and multi-industry blocks, including a different combination of industries and their advantages and disadvantages. It is concluded that the most effective is an industry-specific model with a diversified rural economy due to the maximum possible set of various economic forms and activities that meet the needs of the population in employment.
