The article is focused on the organizational and methodological algorithm of the economic scientific research. Methods of economic research have been systematized according to its stages. Priorities and development trends in methodological approaches to economic space have been specified. Complex evaluation of the researched object's constituent elements' performance is of great importance and is viewed as a characteristic of the object which results from simultaneous and coordinated study of various indices reflecting all the aspects of the economic processes; it comprises generalization of the performance results of the production facilities, being based on the qualitative and quantitative deviations from the comparative base. The research rationalizes the application of the coordinates matrix method and elaborates its algorithm. It also proves that studying external environment as an impact factor on the object's condition provides the foundation for the situation analysis which has the purpose of studying a separate situation, evaluation of the impact factors, mechanisms, risks and obstacles and ways of overcoming them. The article presents a methodological support system which provides for the functioning of the sectoral production.
