Research on the Impact of Digital Economy on the Efficiency of Real Economy in Chinese Cities
Based on the panel data of 275 prefecture-level and above cities in China from 2011 to 2019,the Super-SBM model and principal component analysis were used to measure the efficiency of China's urban real economy and the level of digital economy,respectively,and the impact of digital economy on the efficiency of real economy and its mechanism of action were explored using the panel model.The study finds that:1)The efficiency of China's real economy as a whole is on the rise,with the most pro-nounced in the central and western regions,but the regional disparity is deepening while the efficiency is improving.2)The digital economy in China's cities during the study period can effectively improve the efficiency of the real economy,and also drive the progress of green efficiency of the real economy.3)There is a certain heterogeneity in the efficiency of digital economy on real economy,which mainly shows that the effect of digital economy on the efficiency of real economy is more significant in city clusters,central city clusters,eastern city clusters,peripheral cities and conventional cities.4)The digital economy can improve the efficiency of the real economy through industrial structure upgrading and talent gathering,with industrial structure upgrading playing a slightly better bridging role than talent gathering.
