【Abstract】

Consumption plays an important role in promoting economic growth. However, there is an obvious spatial segmentation of consumption. Based on the consumption data of UnionPay in the middle reaches of the Yangtze River, this paper studies the inter-city consumption flow for the first time, and makes an empirical analysis of the phenomenon of spatial segmentation of consumption by establishing a boundary effect model affecting consumption. The study finds that, at the provincial level, the provincial borders have significant barrier effects on inter-city consumption flows. At the municipal level, urban borders have both mediating and barrier effects, and have regional heterogeneity. The deviation of border effects between provincial and municipal scales eventually results in spatial segmentation of urban consumption. In order to reduce the barrier effect of borders and solve the consumption segmentation, it is necessary to strengthen the consultation between provincial and municipal governments and strengthen the communication and cooperation among Hubei, Hunan and Jiangxi provinces to realize the win-win situation.
