Integration of Digital Economy and Real Economy, Industrial Chain Resilience and New Industrialization—Based on the Moderated Mediating Effect Test

文章基于2012~2022年中国30个省级面板数据，实证检验数实融合对新型工业化影响效应和作用机制。研究发现：(1) 数实融合对新型工业化发展具有显著促进效应。(2) 产业链韧性在数实融合赋能新型工业化建设中发挥中介作用。(3) 产业协同集聚可正向调节数实融合对新型工业化的影响，且对产业链韧性的中介效应也具有正向调节作用。(4) 由异质性分析可知，数实融合对东部地区、数实融合水平较发达地区新型工业化建设的促进作用更显著。(5) 进一步检验发现，数实融合对新型工业化的促进效应存在基于数实融合水平的单门槛效应。Based on the data of 30 provincial panels in China from 2012 to 2022, this paper empirically tests the impact effect and mechanism of the integration of digital economy and real economy on the new industrialization. Results have shown that: (1) The integration of digital economy and real economy has a significant promoting effect on the development of new industrialization. (2) Industrial chain resilience plays a mediating role in the construction of Chinese new industrialization enabled by the integration of digital economy and real economy. (3) Industrial collaborative agglomeration can positively regulate the influence of the integration of digital economy and real economy on Chinese new industrialization, and also has a positive moderating effect on the mediating effect of industrial chain resilience. (4) From the heterogeneity analysis, it can be seen that the integration of digital economy and real economy plays a more significant role in promoting the new industrialization construction in the eastern region and the regions with more developed integration level of digital economy and real economy. (5) Further examination reveals that there is a single threshold effect based on the integration level of digital economy and real economy.
