Digital Transformation,Green Innovation,and Total Factor Productivity of Enterprises
Taking A-share listed companies from 2009 to 2022 as samples,this paper analyzes the evolution trend of total factor productivity(TFP)in the process of enterprise digital transformation by using systematic GMM model and intermediary effect method.Research has found that:①The total factor productivity of enterprises is significantly promoted by digital transformation,reflecting a distribution pattern of"high in the central and west-ern regions and low in the eastern region";②the regression coefficients of enterprise digital transformation on the total factor productivity of non-state-owned enterprises and enterprises with fierce industry competition are 0.074 and 0.106,respectively,both of which are positively significant at the 1%level.The regression coefficient of en-terprise digital transformation on the total factor productivity of enterprises with low social responsibility is 0.131,which is positively significant at the 5%level;③when the level of green innovation crosses the specific threshold of 4.6347,the regression coefficient of digital transformation on the total factor productivity of enterpri-ses further increases from 0.025 to 0.069.Based on this,the promotion of digital transformation should be deep-ened;an innovative environment throughout the entire chain should be constructed;healthy competition among various industries should be guided;the"short board"of green innovation should be turned into a"springboard",and the total factor productivity of enterprises should be further unleashed.
