Because there were many old industrial bases in the northeast in the early days of liberation, it played a considerable role in the early economic development of the country. However, with the development of the times, after the reform and opening up, new high-tech industrial enterprises have risen in the central and eastern regions, and the old industries have gradually fallen behind the times, gradually showing the problems of high energy consumption and low output. In order to get rid of the old business model and production technology, revitalize the old industrial base in Northeast China and make further contributions to China's economy, the central government has made a major strategic decision to revitalize the old industrial base. Its main idea is to inject new business models, high-tech production equipment, technological innovation, enterprise restructuring and other large-scale enterprise reforms.
