Research on the Impact of Digital Transformation on the Upgrading of Innovation Chain——From the Perspective of Product Bargaining Power of Innovative Industries
Promoting the digital transformation of enterprises is a key foothold for building Digital Chi-na.In the context of the innovation-driven development strategy,digital transformation injects new mo-mentum into the upgrading of the innovation chain and high-quality economic development.This article u-ses a bilateral stochastic frontier model based on the CEPII-BACI 6-digit code from 2007 to 2021 and the World Bank's WDI database to calculate the bargaining power index of export products in China's innova-tion industry,measure the upgrading of innovation chains from the perspective of technology industrializa-tion,and test the impact of digital transformation on the upgrading of innovation chains.The results indi-cate that digital transformation is conducive to promoting innovation chain upgrading,and the innovation cooperation effect and information spillover effect among innovation units are the main pathways through which digital transformation promotes innovation chain upgrading.The results of the heterogeneity analysis indicate that the empowering effect of digital transformation on the upgrading of the innovation chain is more significant in industries with higher levels of innovation cooperation,but it is not affected by the density of industry R&D personnel,industry risks and external uncertainties.The research theoretically proves the promoting effect of digital transformation on the upgrading of the innovation chain,and provides empirical support and policy basis for promoting digital transformation,strengthening technological innovation,and stabilizing the driving force of industrial innovation development
