The third is to form a mechanism of complementary advantages and benign interaction in regional relations. This is the guarantee of regional coordinated development. The development of the whole country is a whole, and the industrial distribution in various regions cannot be self-contained or comprehensive. It is necessary to strengthen regional economic ties, enhance the competitive advantage and economic benefits of the whole country, and avoid repeated construction, mutual blockade and industrial structure convergence. To this end, we must adhere to the overall strategy of regional development, promote the large-scale development of the western region, revitalize the old industrial bases such as Northeast China, promote the rise of the central region, and encourage the eastern region to take the lead in development. At the same time, it is necessary to increase support for old revolutionary base areas, ethnic minority areas, border areas and poverty-stricken areas. Comply with the trend of economic globalization and the requirements of optimal allocation of production factors, encourage the orderly transfer of industries between regions and the rational flow of labor capital, and strive to build a new pattern of regional coordinated development.
