Regional planning is an important element of the mechanism of market transformation in the economy of the region based on information technology management. The content of the plans is largely determined by the scenario of its development. However, it is necessary to determine the specifics of organizational support and the choice of a scenario for market transformation at the mesoscale. The objective of the research is to determine the specifics of organizational support and choose a scenario for market transformation at the mesoscale. Based on a study of the results of the implementation of the scenario of economic development, the main causes and trends of the regional economy are identified, and regulatory measures in the region are proposed. On the example of the regions of Ukraine, three possible scenarios of the scenario were formed in the near future: innovative, raw, paternalistic. The main criteria for all scenarios is the development of energy-saving technologies; the formation of a middle class that will ensure the modernization of social infrastructure, the development of education and health care, the improvement of the environment, the creation of an effective housing and communal economy and the beginning of the movement towards civil society.
