摘　　要：为探究黄河流域数字经济与制造业绿色全要素生产率之间的内在联系,基于2011—2020年黄河流域73个地级市的面板数据,运用系统GMM模型和面板门槛模型,实证分析数字经济对黄河流域制造业绿色全要素生产率的影响效应。结果表明,数字经济能够显著促进黄河流域制造业绿色全要素生产率的提升,且这一促进作用表现为边际递增的非线性特征。进一步考察发现,数字经济对制造业绿色全要素生产率的影响存在基于对外开放、政府支持的单一门槛效应。区域异质性检验结果表明,数字经济对黄河中下游地区制造业绿色全要素生产率的提升效果更为显著。In order to explore the internal relationship between digital economy and green total factor productivity of manufacturing industry in the Yellow River Basin,this paper empirically analyzed the impact of digital economy on green total factor productivity of manufacturing in⁃dustry in the Yellow River Basin by using systematic GMM model and panel threshold model based on panel data of 73 prefecture⁃level cities in the Yellow River Basin from 2011 to 2020.The result shows that digital economy can significantly promote the improvement of green total factor productivity of manufacturing industry in the Yellow River Basin,and this promoting effect is nonlinear with marginal increasing.Further investigation shows that the impact of digital economy on green total factor productivity of manufacturing industry has a single threshold effect based on opening to the outside world and government support.Heterogeneity analysis shows that digital economy has a more significant effect on the improvement of green total factor productivity of manufacturing in the middle and downstream regions.
