摘　　要：我国已进入全面建设社会主义现代化国家的新发展阶段,实现高水平科技自立自强的内在需求日益凸显,不断重塑区域创新格局。基于省级面板数据,采用系统GMM估计方法,从规模与结构双维空间相对差异视角切入,探究研发投入强度与结构变化对区域创新绩效的动态影响,进而把握创新格局演进的内在机理。结果发现:研发投入强度、结构变化对区域创新绩效存在显著影响;分区域看,研发投入强度、结构变化对东部、西部创新绩效的影响显著不同于其对中部的影响。因此,不同类型区域应全面认识研发投入强度及其结构的动态演化产生的异质性影响,提升区域科技政策的精准性、靶向发力。With our country having entered the new stage of building a socialist modernization country in an all-round way,the internal demand for self-reliance and self-strengthening in science and technology at high levels is becoming increasingly prominent which constantly reshaping the regional innovation pattern.Based on the provincial panel data,using the systematic GMM estimation method,from the perspective of the relative difference between scale and structure two-dimensional space,the paper explores the dynamic impact of the relative intensity of R&D investment and the change of structure on regional innovation performance,and then grasps the internal mechanism of the evolution of regional innovation pattern.The results show that:The relative intensity of R&D and the change of structure have significant effects on regional innovation performance;By region,the influence of R&D relative intensity and structure change on innovation performance in the eastern and western regions is significantly different from that in the central region.Therefore,different types of regions should fully understand the differential impact of the relative intensity of innovation input and the dynamic evolution of its structure,so as to improve the precision and targeted development of regional science and technology policies.
