数字经济发展能否缓解工业用地要素错配

Whether the Development of Digital Economy Can Alleviate the Misallocation of Industrial Land Resources

研究目的:探究数字经济发展对工业用地要素错配的影响效应及机制,为深化工业用地要素市场化配置改革,助推工业经济高质量发展提供决策参考。研究方法:双向固定效应模型、中介效应模型回归分析。研究结果:(1)数字经济发展抑制了工业用地要素错配,一系列稳健性检验后结论依然成立;(2)数字经济能通过提升绿色全要素生产率和工业结构高级化两条渠道抑制工业用地要素错配;(3)对市场化程度较低、互联网发展规模较大、过度错配城市以及非资源城市的抑制作用更显著;(4)抑制作用随着错配程度的降低而逐渐减弱,并能推动土地出让结构向增加商住用地方向调整。研究结论:应加强数字经济基础设施建设,强化数字经济赋能效应,统筹兼顾全国数字产业空间布局,充分发挥数字化技术对工业用地要素错配的矫正作用。

The purpose of this study is to explore the effects and mechanisms of digital economy on the misallocation of industrial land resources,to provide decision-making reference for deepening the market-oriented allocation reform of industrial land resources and for further promoting the high-quality development of industrial economy.The research method is to conduct regression analysis using a two-way fixed effects model and a mediation effect model.This research results show that:1)the development of digital economy has inhibited the misallocation of industrial land resources,which is held after a series of robustness tests.2)Digital economy has inhibited the misallocation of industrial land resources through two channels of improving green total factor productivity and upgrading industrial structure.3)The effect of digital economy is stronger in cities with a lower degree of marketization and larger scale of Internet development as well as in excessive mismatch and non-resource cities.4)The inhibitory effect of digital economy on the misallocation of industrial land resources weakens with the decrease of mismatch degree.It has promoted the adjustment of land transfer structure towards increasing the proportion of commercial and residential land.In conclusion,we should further strengthen the construction of digital economic infrastructure,enhance the enabling effect of the digital economy,coordinate the spatial layout of digital industries across the country,and fully leverage digital technologies to correct the misallocation of industrial land resources.
