数字技术对制造业生产效率的影响研究OA

In the context of the digital economy,exploring the impact of digital technology on the pro-duction efficiency of manufacturing is of great significance in promoting the deep integration of digital technology and manufacturing.Based on the panel data from some provinces in China from 2006 to 2021,this paper makes a theoretical analysis of the impact of digital technology levels on the produc-tion efficiency of manufacturing.Then it measures the digital technology level and the production effi-ciency of manufacturing of each province with the entropy method and DEA-Malmquist productivity in-dex method.It also makes a benchmark regression analysis and a mechanism test with the fixed effects model and the mediating effects model.Finally,it analyzes the differences in the impact of digital tech-nology on the production efficiency of manufacturing in different research and development intensities and labor force sizes with the group regression method,hoping to provide reference for making policies to improve the production efficiency of manufacturing.
