This paper selects other major cities in the Yangtze River Delta economic circle as the comparison object to Wuxi with the Three-stage DEA model, analyzing the operating efficiency of listed companies in advanced manufacturing industry, so as to more clearly understand the current situation about the operating efficiency of advanced manufacturing industry in Wuxi. According to the studies, a significant impact of the external environment on the operating efficiency of advanced manufacturing enterprises has been found, and the operating efficiency of advanced manufacturing industry in major cities around the Yangtze River Delta is at a high level. However, the reduction of scale efficiency has become the main factor restricting the growth efficiency of advanced manufacturing industry without the influence of external environmental factors. The study puts forward the suggestions on the creation of a good market environment, construction service and ecological system based on this with the improvement of transportation infrastructure and no blind investment, promoting the deep integration of manufacturing industry and digital technology.
