摘要
使用2011—2021年我国的280个地级及以上城市数据,采用GS3SLS方法实证检验了数字产业化、产业数字化与中国城市高质量发展之间的相互影响与空间作用。结果显示:三个变量均有显著的正向空间溢出效应,但所有交叉回归系数均在1%水平上负显著。在同一城市内部,数字产业化、产业数字化与高质量发展之间可以相互促进,产业数字化对高质量发展的影响明显高于数字产业化,高质量发展对数字产业化与产业数字化对数字产业化的促进作用显著高于反向促进作用,产业数字化可以同时促进经济、绿色、协调与共享发展,而数字产业化对协调发展的影响不显著。上述结果的异质性主要受城市规模而非区位影响。数字创新、效率提升与产业结构优化的中介效应同时体现出数字产业化与产业数字化之间的差异和区域差异。当人口规模超过门槛值时,产业数字化对高质量发展的促进作用与高质量发展对产业数字化的带动作用转变为负显著。
Using data from 280 prefecture-level and above cities from 2011 to 2021,this study empirically examined the mutual influence and spatial interaction between digital industrialization,industrial digitalization and high-quality urban development in China by using the GS3SLS method.The results reveal that:all three variables have significant positive spatial spillover effects,but all the cross-regression coefficients are negatively significant at the 1%level.Within the same city,digital industrialization,industrial digitalization and high-quality urban development can mutually promote each other and the role of industrial digitalization in promoting high-quality urban development is significantly higher than that of digital industrialization,high-quality development exhibits a significantly stronger promoting effect on digital industrialization than the reverse effect.Industrial digitalization can simultaneously promote economic,green,coordinated,and shared development.whereas digital industrialization has no significant impact on coordinated development.The heterogeneity of the above results is primarily driven by city size rather than location.The mediating effects of digital innovation,efficiency enhancement,and industrial structure optimization simultaneously reflect the differences between digital industrialization and industrial digitalization,as well as regional disparities.When the population size exceeds the threshold value,the promoting effect of industrial digitalization on high-quality urban development and the driving effect of highquality urban development on industrial digitalization turn significantly negative.
