摘要
数字经济是经济发展提质增效的新动能和新引擎,对产业结构的转型升级具有重要驱动作用。在理论分析的基础上,从产业转型速度、产业结构高度化以及产业结构合理化三个维度对产业结构的转型升级进行分解,以区域创新创业指数表征城市创新创业水平,采用2011—2018年我国城市面板数据实证考察数字经济发展的产业结构转型升级效应及其作用机制。研究发现:(1)数字经济能显著提升产业转型速度、产业结构高度化和产业结构合理化,且基于互联网发展和数字普惠金融发展的分析结果趋同。(2)数字经济对产业结构转型升级的效应具有边际报酬递增的后发性优势,且东中西部区域异质性特征明显,其中中部地区是未来数字经济发展的重心。(3)从城市规模看,中等城市和大城市是数字经济驱动产业转型升级的重要着力点;从城市等级来看,二三线城市是产业转型的关键所在。(4)中介效应分析显示,创新创业水平是数字经济产业转型升级效应的重要传导路径,数字经济通过激发区域创新创业活力可加快产业转型速度、促进产业结构的高度化和合理化。以上结论对探索中国城市数字经济可持续发展、助推其与产业结构转型升级深度融合具有一定的参考意义。
Digital economy is a new driving force and engine for improving the quality and efficiency of today’s economic development.It plays an important driving role in the transformation and upgrading of industrial structure.On the basis of theoretical analysis,this paper decomposes the transformation and upgrading of industrial structure from the speed of industrial transformation,the upgrading of industrial structure and the rationalization of industrial structure,characterizes the level of urban innovation and entrepreneurship with the regional innovation and entrepreneurship index,and empirically investigates the effect and mechanism of industrial structure transformation and upgrading of digital economy development by using China’s urban panel data from 2011 to 2018.It is found that digital economy can significantly improve the speed of industrial transformation,the height of industrial structure and the rationalization of industrial structure,and the analysis results based on the development of Internet and the development of digital inclusive finance converge;the effect of digital economy on the transformation and upgrading of industrial structure has the late developing advantage of increasing marginal return,and the heterogeneity of the three regions is obvious but the central region is the focus of developing digital economy in the future;from the perspective of city scale,medium-sized cities and large cities are the important focus of industrial transformation and upgrading driven by digital economy,while from the perspective of city level,second and third tier cities are the key to industrial transformation.The intermediary effect analysis shows that the innovation and entrepreneurship level is an important transmission path of the industrial transformation and upgrading effect of the digital economy;digital economy can accelerate the speed of industrial transformation and promote the upgrading and rationalization of industrial structure by stimulating the vitality of regional innovation and entrepreneur
