Research on the Scale Measurement and Circulation of China's Digital Economy Industry Chain
Compared with the world's major and powerful digital economy countries,the development of China's digital economy is large but not strong and fast but not optimal.Therefore,continuously strengthening,optimizing,and expanding China's digital economy objectively requires a clear judgment of its digital economy industry chain and the smooth development of its digital economy industry chain.Therefore,based on the"Statistical Classification of Digital Economy and Its Core Industries(2021)"released by the National Bureau of Statistics,this article uses China's input-output table data from 149 departments in 2017,153 departments in 2018,and 153 departments in 2020.Under the determination of the classification standards for the upstream,midstream,and downstream industries of the digital economy industry chain,the input-output table of China's digital economy industry chain is compiled to measure the scale of the upstream,midstream,and downstream industries of China's digital economy industry chain and analyze the interaction and connection status in the digital economy industry chain;the correlation between upstream,midstream,and downstream industries in the digital economy;and the final demand effect.The main findings are as follows.First,the digital economy has become an important engine of China's economic growth.However,from the perspective of the internal structure of the digital economy industry chain,the scale of upstream and midstream industries is much larger than that of midstream industries in the digital economy,and the growth rate of downstream industries in the digital economy exceeds the overall growth rate of the digital economy industry chain and the growth rate of GDP during the same period.Moreover,the leading industry in the digital economy industry has shifted from the upstream industry in 2017 to the downstream industry in 2020.It can be recognized that the scale of the upstream,midstream,and downstream industries in the digital economy is"dumbbell shaped,"and there are problems with the circulation of China's digital economy industry chain.The mismatch and disconnect between the demand-and supply-driven industries in the midstream and downstream of the digital economy have affected the cyclization of the digital economy industry chain to some extent.Second,from the perspective of the industrial structure coefficient,the influence coefficient of midstream industries in the digital economy is the highest,indicating that they have a strong radiating effect on the national economy.The driving force coefficient of downstream industries in the digital economy is the highest,playing an important supporting role in the development of the national economy.Further,both the upstream and downstream industries of the digital economy are cycle-sensitive industries,which are greatly affected by the externalities of national economic development.Third,from the sensitivity analysis of final demand,both the upstream and downstream industries of the digital economy are investment-dependent industries,while the midstream industries of the digital economy are consumption,investment,and net export-dependent industries.A comparison of the three major industries reveals that final consumption has the greatest inducing effect on the downstream industries of the digital economy;total investment has a greater inducing effect on both the upstream and downstream industries of the digital economy;and net exports have a greater inducing effect on the midstream industries of the digital economy,which is much higher than the inducing effect of consumption.The midstream industries of the digital economy are seriously uncoordinated by the inducing effects of internal and external circulation.The findings of this article can provide theoretical support and policy recommendations for the national strategy of continuously strengthening and optimizing China's digital economy.
