Abstract: Many problems facing the economic development of Northeast China are not only the outbreak of internal contradictions accumulated for many years, but also the inevitable manifestation of the “three-phase superposition” in the old industrial base of Northeast China under the new normal economic situation: the lack of vitality of the main body of the micro-market, the failure to form a market competition mechanism for the common development of various forms of ownership and the cooperation of large and medium-sized enterprises, and the evolution of the inertia of the sick industrial structure into a market;institutional defects, lack of institutional innovation and anti-industrialization of economic development in individual periods have not yet formed a business environment for the development of new industries and the transformation of new and old power, so it is urgent to bring the modernization of local government governance system and governance capacity into the research field. Starting from the structural reform of the supply side, the adjustment of the industrial structure of Northeast China′s economy should be based on the structural changes of the mode of production and all kinds of industries. The top-level design of the government′s governing ability should be carried out through the innovation of mechanism, institution and system, so as to consolidate the realistic foundation of sustainable and stable development of Northeast China′s economy, and strive to enhance the competitiveness of all kinds of industries to solve the supply problem of the old industrial base in Northeast China.

Key words: old industrial base in Northeast China, supply-side structural reform, governance ability of government, Marxist Political Economy
