Before 1990s, Northeast China, as a relatively developed area in China, was also the most important industrial base in China. However, compared with the regions with rapid economic development, the economic development in Northeast China is still slow. GDP and industrial added value have dropped from nearly 15% and 20% at the beginning of reform and opening up to below 10% now. From June 5, 2003 to 10, the Central Committee and the State Council issued "Several Opinions on Implementing the Revitalization Strategy of Old Industrial Bases in Northeast China" (hereinafter referred to as "Several Opinions"), which clarified the guiding ideology, principles, tasks and policy measures for implementing the revitalization strategy. With the implementation of the revitalization strategy, Northeast China has accelerated the pace of development. At present, the social security pilot, the transformation of value-added tax, the exemption of historical tax arrears of enterprises, the policy bankruptcy of state-owned enterprises, the separation of social functions of central enterprises, and the reform of large collective factories have been implemented. The broad masses of cadres and people in the three northeastern provinces have made great efforts to change their ideological concepts, increase the pace of system innovation, mechanism innovation and opening up, and solidly promote all work. Implementing the strategy of revitalizing Northeast China has a long way to go and requires innovative thinking and action. Consolidating and upgrading the position and role of the most important commodity grain production base, important forestry base, energy and raw material base, machinery industry and pharmaceutical industry base in China is the key foundation for revitalizing Northeast China.

Since the implementation of the strategy of revitalizing the old industrial base in Northeast China, the economic and social development in Northeast China has accelerated, and the development gap opened since the reform and opening up has narrowed year by year, surpassing the national average growth rate. Northeast China has taken the lead in implementing the policy of exempting agricultural taxes and benefiting farmers, and the grain output has hit record highs, and the status of the national commodity grain and meat supply base has become increasingly prominent. Significant progress has been made in institutional and institutional innovation focusing on the restructuring of state-owned enterprises. Most state-owned enterprises turned losses into profits, got rid of difficulties, increased profits substantially, and significantly improved the level of opening up. The technological progress of enterprises has achieved remarkable results, and the pace of structural adjustment has accelerated. "Popular projects" such as the treatment of coal mining subsidence areas and the transformation of shanty towns are progressing smoothly, and the pilot project of economic transformation in resource-based cities is progressing steadily. Infrastructure has been continuously improved, and positive results have been achieved in ecological construction and environmental protection. The urban social security system was initially established, the employment situation improved significantly, and the income of urban and rural residents increased steadily.

Since the implementation of the strategy of revitalizing the old industrial base in Northeast China, the economic growth rate of the three northeastern provinces has begun to accelerate, gradually narrowing the development gap with the whole country. In 2008, the proportion of the three northeastern provinces in GDP rose to 8.62%, which was 0. 14 percentage points higher than that in 2007. This is the first time that the proportion of GDP in the three northeastern provinces has stopped falling and rebounded after entering the new century.

In 2008, the GDP growth rate of the three northeastern provinces (converted by regional statistics) was 13.4%, exceeding the national average of 1.7 percentage points, ranking first among the four major sectors (see table 2 for details). Calculated in the three years since the implementation of the Eleventh Five-Year Plan, the economic growth rate of the three northeastern provinces is 13.7%, which is 0.5 percentage points higher than that of the whole country and 0.5, 0.5 and 0.3 percentage points higher than that of the eastern, central and western regions respectively, which is the fastest growth period since the reform and opening up.

Revitalizing the old industrial base in Northeast China has a long way to go. Since the implementation of the strategy of revitalizing the old industrial base in Northeast China for more than three years, the existing national policies, funds and project support have basically been put in place, and the economic development and social progress of the three northeastern provinces have made positive and gratifying achievements, and the people's ideological concepts and mental outlook have undergone profound changes. However, we should also be soberly aware that the achievements of the three northeastern provinces are only phased, and there is still a big gap compared with the whole country, especially the developed regions. The economic aggregate is still declining, the task of structural adjustment is very arduous, it is difficult to deepen the strategic reorganization of state-owned enterprises, the sustainable development of equipment manufacturing industry is facing challenges, the sustainable development of resource-based cities lacks policy guarantee, employment, people's livelihood and social security are under great pressure, and many risks still exist. In particular, the ideological transformation and institutional innovation in the three northeastern provinces, as well as some structural and institutional contradictions accumulated in history that affect long-term development, have not been completely resolved. Revitalizing the old industrial base in Northeast China is a long-term, complex and arduous task, and it is a long way to go to fully realize the revitalization goal.
