| The construction of the global value chain is an important manifestation of international division of labor and cooperation.China’s manufacturing industry is crucial in this chain,integrating into the division of labor system with its advantages such as population dividends and low costs,and consolidating its position as a hub for intermediate goods processing and trade.However,with the outbreak of financial crises and major public health events,the global value chain faces the risk of interruption.The development speed of the domestic value chain has surpassed that of the international processing links,therefore,it is imperative to reconstruct the global value chain.The digital innovation brought about by the development of the digital economy,as a driving force for innovation,plays an important role in optimizing the division of labor in the GVCs.The scale of China’s digital economy has seen remarkable growth in recent years,surpassing 39 trillion yuan in 2021.Under the wave of industrial digital transformation,the manufacturing industry in China is undergoing digital upgrading,aiming to strengthen the application of digital technology,optimize the mode and efficiency of digital manufacturing,improve the overall level of the manufacturing industry,and better integrate into the production division of the GVCs,from the supply chain to the production chain and further to the value chain,with digital technology as the core.This article constructs a matrix of digital innovation value-added and measures the production and consumption of digital innovation based on cross-border inputoutput tables from the OECD database from 2009 to 2018 and the WIOD database from 2000 to 2014.Firstly,using the input-output model,the paper measures four paths for digital innovation input to empower China’s manufacturing industry to integrate into the global value chain,as well as the upstream and downstream production lengths and relative production position index of the global value chain,and obtains the basic hypothesis of the article.Then,the hypothesis is tested based on empirical regression models,and the heterogeneity of technology intensity and industry reliance on digital innovation in China’s manufacturing industry is discussed to further verify the correctness of the basic hypothesis."There are four main conclusions:1)The incorporation of digital innovation is increasing the level of integration of China’s manufacturing industry into the GVCs,with closer production connections with developed countries and relatively less production connections with developing countries.Meanwhile,manufacturing industries with higher levels of technological intensity are more deeply integrated into the global value chain.2)Digital innovation input shortens the upstream production length of China’s manufacturing industry in the global value chain and moves its production position towards relatively downstream links.3)Industries with different levels of technological intensity have different degrees of absorption of digital innovation.Manufacturing industries with higher levels of technological intensity show a more significant trend towards shortening the upstream production length and moving their production position towards downstream links with higher value-added.The utility of digital innovation in empowering China’s manufacturing industry to integrate into the GVCs through digital transaction is greater than that of digital technology infrastructure investment.Based on the above conclusions,this paper suggests that China’s manufacturing industry should strengthen the construction of digital infrastructure,implement the digitalization of the industry ecosystem,deepen the "Belt and Road" initiative,and build a digital community of shared destiny under the "Belt and Road" framework.These measures can promote the upgrading of China’s domestic digital elements,boost its position in the global value chain,and better integrate into the "dual circulation" of the international and domestic digital global value chain. |
