——the Empirical Research on 283 Cities at the Prefecture Level and Above LIU Ming
（School of Business and Tourism Management，Yunnan University，Kunming 650091，Yunnan，China） Abstract：Using the panel data of 283 cities at the prefecture level and above in China from 2007 to 2019 and the principal component analysis，the author constructs a high-quality economic development indicator system to measure the level of highquality economic development; and the author also uses the system GMM model and the panel threshold model to explore the linear and non- linear influence of collaborative agglomeration of logistics industry and manufacturing industry on high- quality economic development. Relevant empirical research shows that: in the full sample ，the collaborative agglomeration of logistics industry and manufacturing industry has a significant positive impact on the high-quality economic development; in the sample of sub-regional location and city size，its impact shows strong regional and scale differences. The eastern and central cities have a significant promoting effect，while the western cities have a significant inhibitory effect; large and medium- sized cities have a significant promoting effect，and small cities have an insignificant effect. Moreover ，the coordinative agglomeration of logistics industry and manufacturing industry has a significant threshold effect on the high- quality economic development. It shows that only by surpassing the low- level threshold and pushing the collaborative agglomeration of logistics industry and manufacturing industry to a higher level can the agglomeration efficiency be truly released and the role of that in high- quality economic development be truly demonstrated. It also further verifies the correctness ，necessity，and urgency of the deep integrated development of logistics industry and manufacturing industry. So we must continuously promote the deep integration of logistics industry and manufacturing industry，pay more attention to the quality of collaborative agglomeration ，and fully explore the potential of logistic talents to really promote the economic transformation to the high-quality development.
