经济增长:技术创新与产业结构升级的协同效应

Economic growth-the synergistic effect of technological innovation and industrial structure upgrade

在经济全球化背景下,技术创新是推动中国稳定跨过"结构性减速"阶段的重要动力。基于中国2009-2018年的省级面板数据,构建三种空间权重矩阵,运用空间计量模型实证分析了不同技术创新模式对区域经济发展的影响作用,探讨了"技术创新-产业结构升级"对经济发展的协同效应,并进一步分阶段对比分析了技术创新、产业结构升级与区域经济发展的内在关系。实证结果表明:(1)技术创新与区域经济发展具有显著的空间相关性;且技术引进、模仿创新及自主创新对区域经济发展具有正向促进作用,其中自主创新最为显著。(2)三种技术创新是否可以提速经济发展取决于产业结构高级化程度。随着产业结构的升级,技术引进和模仿创新对经济发展的增速作用逐渐减缓。(3)产业结构升级对经济增速的作用受技术创新投入的影响。在产业结构既定的前提下,技术创新投入越多,产业结构升级的边际经济效应越小。(4)我国在产业结构不断升级的过程中,各产业通过逐步提高其对技术创新投入的承载和吸收能力,实现产业技术水平的全面提升,进而保证区域经济的持续发展。

In the context of economic globalization,technological innovation is an important driving force to promote China’s stability across the structural deceleration phase.Based on the provincial panel data of China from 2009 to 2018,this paper constructs three kindsof spatial weight matrices and uses the spatial econometricanalysis model to empirically analyze the impact of different technological innovation modes on regional economic development.At the same time,this article discusses the Synergistic effect of"technical innovation-industrial structure upgrade"on economic development,and further comparatively analyzes the internal relationship among technological innovation,industrial structure upgrade and regional economic development in different stages.The empirical results show that:(1)Technological innovation has a significant spatial correlation with regional economic development;and technology introduction,imitation innovation and independent innovation have positive promotion effects on regional economic development,among which independent innovation has the most significant role in promoting economic development.(2)Whether the three technological innovations can speed up economic development depends on the degree of advanced industrial structure.With the upgrading of the industrial structure,the effects of technological introduction and imitation innovation on economic growth have gradually slowed down.(3)The effect of industrial structure upgrade on economic growth is affected by technological innovation investment.Under the premise of the established industrial structure,the more technological innovation investment,the smaller the marginal economic effect of industrial structure upgrade.(4)In the process of continuous upgrading of the industrial structure in our country,each industry gradually improves its ability to digest and absorb technological innovation input,so as to achieve a comprehensive improvement of the industrial technology level,thereby ensuring the sustainable development of the regional economy.
