It is understood that in May 2004, the Chinese Academy of Sciences closely focused on the national strategic decision to revitalize the old industrial bases in the Northeast, and quickly introduced the “Northeast Revitalization Science and Technology Action Plan†to provide basic, strategic and forward-looking technologies for the comprehensive, coordinated and sustainable development of the Northeast region. Innovative needs. The action plan mainly includes four projects, namely, “promoting the upgrading and upgrading of traditional industries in the Northeastâ€, “promoting the development of high-tech industries in the Northeastâ€, “promoting the development of modern agriculture and ecological environment in the Northeast†and “strengthening the training and exchange of talentsâ€. From the 38 projects in batches, we will promote the upgrading and upgrading of traditional industries such as petrochemicals, raw materials and equipment manufacturing in Northeast China, and promote high-tech industries such as new materials, new energy, electronic information, opto-mechatronics and biotechnology. The development, solving the key regional technologies and developments in the typical regional ecological environment and agriculture has transformed a number of technological achievements with independent intellectual property rights.
According to reports, since the launch of the “Northeast Revitalization Technology Action Planâ€, nearly 100 mature technology projects have been implemented in the Northeast. High-end numerical control technology puts "brains" on Chinese CNC machine tools; field bus system and chip technology break through the monopoly of foreign technology to realize its industrialization; dry gas production of ethylbenzene continues to innovate and develop in the transformation of results, high definition, high uniformity The color LED display breaks through the key technologies to achieve large-scale production; the “Northeast Spring†talent training program trains and condenses a large number of outstanding scientific and technological talents in the Northeast.
