Spillover Effect of Green Innovation from Enterprises Digital Transformation under Supply Chain Linkage
The digital transformation of enterprises is an important way to promote high-quality economic development.There is a need to explore whether the digital linkage between upstream and downstream enterprises in the supply chain can promote the green development of enterprises.Based on the supply chain linkage effect,this paper studies the spillover effect and the mechanism by which the digitalization of upstream and downstream enterprises in the supply chain impacts focus enterprise's green innovation.We find that the digital transformation of upstream and downstream enterprises has a significant positive impact on the green innovation of focus enterprises,and this conclusion remains significant after a series of robustness tests,including the placebo and instrumental variable methods.The digital transformation of upstream suppliers has a more significant impact on the green innovation of focus enterprises than the digital transformation of those downstream.Further,the spillover of digital green innovation of enterprises in the supply chain is mainly reflected in the technological promotion effect of upstream enterprises.The mechanism test shows that the digital transformation of upstream and downstream enterprises promotes green innovation of focus enterprise through enterprise learning within the supply chain and the attention of stakeholders outside the supply chain.The results of heterogeneity testing show that the spillover effect of the digital transformation of upstream and downstream enterprises on green innovation of focus enterprise is more significant when these are in different industries and geographically close.Finally,this paper finds that upstream and downstream digitalization has had a"leverage effect"in promoting the green innovation output of enterprises,stimulating the input of focus enterprises,and improving the efficiency of green innovation.This paper supports the construction of a digital green supply chain.
