数字经济赋能产业链供应链现代化影响研究

Research on the Impact of Digital Economy Empowering Industry Chain and Supply Chain Modernization

选取2012—2021年中国省级面板数据,借助动态面板GMM估计模型,探讨数字经济能否赋能产业链供应链现代化。研究显示,数字经济能够显著赋能产业链供应链现代化;数字经济对产业链供应链现代化的影响存在明显区域差异,能够显著促进东部地区产业链供应链现代化,对西部地区产业链供应链现代化的影响尚不明显。在经济“双循环”条件下,数字经济对产业链供应链现代化表现出明显边际效率递增的非线性特征;在知识产权保护门槛约束下,数字经济与产业链供应链现代化间存在“U”型作用关系。进一步检验可知,在经济双循环与知识产权保护不同门槛条件下,数字经济对不同分位点处产业链供应链现代化产生不同赋能作用。

Select the China's inter provincial panel data from 2012 to 2021,this paper explores whether the digital economy can e-mpower the modernization of the industrial chain supply chain using a dynamic panel GMM estimation model.Research shows that the digital economy can significantly empower the modernization of industrial and supply chains.There are significant regional differences in the impact of the digital economy on the modernization of industrial and supply chains,which can significantly promote the modernization of industrial and supply chains in the eastern region.The impact on the modernization of industrial and supply chains in the western region is not yet significant.Under the condition of"economic dual cycles",the digital economy exhibits a significant nonlinear characte-ristic of increasing marginal efficiency in modernizing the industrial chain supply chain.Under the constraints of intellectual property protection threshold,there is a"U"shaped relationship between the digital economy and the modernization of the industrial chain supply chain.Further examination shows that under different threshold conditions of economic dual circulation and intellectual property protection,the digital economy has different empowering effects on the modernization of the industrial chain supply chain at different quantiles.
