摘要
Abstract
In the context of the continuous broadening of the"Internet"boundary,based on the sample of A-share service industry listed companies in Shanghai and Shenzhen from 2010 to 2021,the text analysis and word frequency statistics methods of machine learning are exploited to measure the digitization level of service companies quantitatively,and the effect of digitization on the total factor productivity of service industry is empirically analyzed in this paper.The research findings show that:in terms of development trends,the digitalization level of service companies in China is continuously increasing,laying the foundation for the improvement of their productivity.In terms of empirical analysis,the digitalization of service companies can significantly promote the improvement of their total factor productivity,the conclusion remains valid after a series of robustness tests.In terms of heterogeneity tests,the empowerment effect is more pronounced in non-state-owned companies,companies in the central and western regions,companies with low levels of digitalization,and companies in the production-oriented service industry.This conclusion provides micro evidence for the digital empowerment of the service industry,which is conducive to the formulation,adjustment,and effect evaluation of industrial policies and corporate decision-making in the future.关键词
