新质生产力、创业活跃度与城市高质量发展

New Quality Productive Forces,Entrepreneurial Activity and High-Quality Urban Development

基于2011-2021年中国244个地级市面板数据,从创业活跃度视角研究新质生产力对城市高质量发展的影响,探究产业结构升级、人才集聚、科技创新的门槛效应,并进一步分析新质生产力对城市高质量发展的空间溢出效应。研究结果表明:整体上,新质生产力显著促进城市高质量发展;异质性分析显示,在金融发展水平、人才资本水平高的城市,新质生产力对高质量发展呈现明显的促进作用;新质生产力对城市高质量发展的推动作用会随着产业结构升级、人才集聚以及科技创新水平提高而增强,呈现显著的门槛效应;新质生产力对高质量发展具有正向空间溢出效应。

New-quality productive forces are generated by scientific and technological innovation and the realization of key disruptive technological breakthroughs,and it is a powerful engine for high-quality development.New quality productive forces,with strategic emerging industries and future industries as the leading industries,are mainly involved in fields with strong innovation and advanced technologies and are committed to empowering regional high-quality development through scientific and technological innovation.In order to maintain a leading position in the competitive global environment and promote China's high-quality economic growth,it is necessary to stimulate industrial innovation through major disruptive scientific and technological innovations,facilitate transform and upgrade the industrial structure to create a new competitive advantage,and endeavor to cultivate the new quality productive forces.The high-quality development of cities,as important spatial carriers and geographic activity units for economic and social development,remains an important issue of our time.Can new productive forces,as a key initiative to reshape new dynamics,be an important way to help cities develop in a high-quality manner If so,what is the internal logic of new-quality productive forces influencing the high-quality development of cities?An overview of the existing literature shows there is a relative lack of empirical research on the relationship between the two.In view of this,this paper tries to put the new quality productive forces and high-quality urban development in the same research framework,and takes entrepreneurial activity as the starting point to explore the mechanism of new quality productive forces on high-quality urban development,so as to further provide a theoretical and practical basis for China's high-quality development.Employing the panel data of 244 prefecture-level cities in China from 2011 to 2021,this study explores the intrinsic mechanism by which new quality productive forces affect the high-quality development of cities,using new quality productive forces as the entry point.Building on this foundation,the study examines the transmission mechanism through which new quality productive forces influence high-quality urban development by enhancing entrepreneurial activity,with entrepreneurial activity serving as the mediating variable.Subsequently,it delves into the non-linear influence of new quality productive forces on high-quality urban development at varying stages of industrial structure upgrading,talent concentration,and scientific and technological innovation.Then,the study investigates the non-linear impact of new productive forces on high-quality urban development when industrial structure upgrading,talent concentration,science and technology innovation are at different stages,and finally,it analyzes the spatial spillover effect of new productive forces on high-quality urban development according to the spatial levels.The study finds that(1)new productive forces have a direct role in promoting high-quality development,and from the perspective of the financial environment of entrepreneurship and the level of talent capital,cities with a higher level of financial development and talent capital have an obvious role in promoting high-quality development;at the same time,entrepreneurial activity is an important channel through which the new productive forces promote the high-quality urban development.(2)The impact of new quality productive forces on high-quality urban development is affected by the threshold effect of industrial structure upgrading,talent concentration,and scientific and technological innovation level,and the impact of new quality productive forces on high-quality urban development presents a non-linear effect of increasing marginal utility under the development level of higher threshold variables.(3)The impact of new quality productive forces on high-quality development has a significant positive spatial spillover effect,and the development of local new quality productive forces can drive the high-quality development of areas with close economic ties.Possible marginal contributions of this article are that,firstly,from the perspective of empirical measurement,the study explores the mechanism of the impact of new quality productive forces on high-quality urban development,and focuses on the impact of new quality productive forces on the high-quality development of cities;moreover,by incorporating industrial structure upgrading,talent concentration and scientific and technological innovation level into the analysis framework,it explores the threshold effect of the new quality productive forces on the high-quality urban development.
