Market segmentation is an important influence factor that causes unbalanced regional economic development in China.Based on the data of 140 cities in China's 9 urban agglomerations from 2005 to 2019,this paper empirically analyzes the influence mechanism of market segmentation on regional economic development gap,and empirically tests its influence path through multiple intermediary effects model.The results go as below:There are great differences in economic development gap and market segmentation among urban agglomerations.There is a U-shaped relationship between market segmentation and regional economic development gap,that is,a lower degree of market segmentation can narrow the regional economic development gap,while a higher degree of market segmentation will expand the regional economic development gap.Further examination of its inter-mediary channels shows that market scale and market competition are the important intermediary channels for market segmenta-tion to affect regional economic development gap,and the impact of market scale is more significant.The effect of market segmen-tation on regional economic development gap is different between central cities and non-central cities.The lower degree of market segmentation in central cities does not bring about the narrowing of regional economic development gap.
