Since the reform and opening up,my country’s economic development has evolved into a”two-track parallel”economic development model.The first track is the national strategic demand industry represented by heavy industry,etc.,and continues to evolve along the national system route since the founding of the People’s Republic of China.The deep integration of production,education and research has formed a perfect internal circulation innovation system,which demonstrates my country’s strong innovation ability.It proves the strong supporting role of technological innovation for the core competitiveness of the manufacturing industry.This track mainly serves the country’s major needs,and it is difficult for technological dividends to spread to the main economic battlefield.
改革开放以来,我国经济发展演进形成了一个“双轨并行”的经济发展模式。第一条轨道是以重工业等为代表的国家战略需求产业,继续沿着建国以来的举国体制路线演进,产学研深度融合,形成了完善的内循环创新体系,彰显了我国强大的创新能力,也证明了科技创新对于制造业核心竞争力的强大支撑作用。该轨道主要服务国家重大需求,技术红利难以扩散至经济主战场领域。
