Taking A-share listed companies as samples, this paper comprehensively applies entropy weight method, LP method, fixed effect model, mechanism test model, instrumental variable method and double difference analysis model to examine the impact of digital economy on total factor productivity of listed companies. The study shows that the development of digital economy can significantly increase the productivity of listed enterprises. And by replacing the digital economy level of prefecture-level cities using principal component analysis and the total factor productivity level of enterprises derived using OP and OLS, the research results still hold. At the same time this effect is more obvious in enterprises, state-owned enterprises and large enterprises in eastern cities. Digital technology innovation and human capital structure optimization are important channels for increasing total factor productivity in the digital economy. The big data pilot region policy can play a policy role in improving the total factor productivity of enterprises. The findings provide important insights for promoting the deep integration of the digital revolution with the technological revolution, accelerating the digital transformation of enterprises and upgrading the industrial structure. %K 数字经济， %K 全要素生产率， %K 数字技术创新， %K 人力资本
