Spatial differences in the efficiency of urban logistics standardization and its interactive spillover effects on industrial structure upgrading

This article assesses the logistics standardization efficiency of 284 cities in China from 2006 to 2022, focusing on the regional differences and their sources and dynamic distribution evolution characteristics. It also uses the spatial simultaneous equation model to explore the spatial spillover effect between the logistics standardization efficiency of cities and the upgrading of the logistics industrial structure. The study finds: 1) The overall logistics standardization efficiency of cities across the country and the three major regions (east, central, and west) has been increasing year by year, but the absolute gap between regions has been continuously expanding; 2) The overall regional difference has been expanding at an average annual growth rate of 5.48%, and the main source of the overall difference is the regional differences and over-density. The differences within the central and western regions are higher than those in the eastern region, and the differences between the eastern and central, and the eastern and western regions are greater than those between the central and western regions. 3) There is a positive interactive effect between the logistics standardization efficiency of Chinese cities and the upgrading of the industrial structure. In the mutual promotion relationship, the upgrading of the industrial structure of cities is in a relatively advantageous position, and both have significant spatial spillover effects and spatial interaction effects in geographical space.
