The historical experience of many countries in the world shows that developed societies have efficient institutions that have played a large role in the realization of development. This has caused institutionalism to become a necessity today that, in addition to the formation of the institutional structure, its functions are also carefully monitored and its effects on the sustainable development of the region are explored. Based on this, this research is trying to use the descriptive-analytical method and use the existing documents; while explaining the concept of institution and institutionalism; investigate the influence of institutionalism in regional development planning and the impact of institutionalism and institutional capacities on sustainable regional development. The results of the research show that institutionalism, instead of focusing on the summary of descriptive and collected statistics in the field of growth and development results, seeks to explain the basic characteristics and type of growth and development. Based on this approach, local separate assets and internal economic capabilities are considered as a basis for development and a foundation for establishing and launching local and regional competitiveness. Institutionalism emphasizes the necessary conditions and foundations for local and regional development. Based on this approach, both formal and informal institutions are considered as an important and integral part in reducing uncertainty and risk and increasing trust in regional development.
