Abstract: This paper elaborates the mechanism of industrial efficiency promotion on the formation of growth poleOn this basis, this paper selects three judging conditions: the level of urban regional contribution rate, the level of urban regional growth rate and the level of urban regional development, and uses the kernel density estimation method to screen and identify whether the 200 prefecture level cities in China can become China's economic growth poles during 2001 and 2018This paper empirically tests the effect mechanism of industrial efficiency on the formation of growth pole, and finds that the improvement of industrial efficiency can significantly promote the formation of growth pole, and its process mechanism is that the improvement of industrial efficiency directly promotes the formation of growth pole on the one hand, and indirectly promotes the formation of growth pole through the upgrading of industrial structure on the other handAt the same time, it is found that road infrastructure and Internet infrastructure indirectly affect the formation of growth pole by promoting industrial efficiencyPopulation size and local fiscal expenditure on science and technology also have significant positive impact on the formation of growth pole
