An Empirical Analysis of Logistics Corridors and Regional Economic Spatial Patterns from the Perspective of Compressive Transportation between Urban Agglomerations

Abstract

From the perspective of 19 urban agglomerations and comprehensive transportation between them, this study, selecting node cities as research units, defines both the narrow and generalized corridor accessibility to calculate the corridor accessibility coefficient by the weighted average travel time and investigates their overall pattern. The gravity model improved by comprehensive-time cost is used to calculate the economic subordination degrees between Lanzhou–Xining urban agglomeration and other urban agglomerations. Moreover, the differences in the spatial distribution of inter-provincial logistics connectivity between the individual and total amount in Gansu province are discussed, and then the unbalanced trend of spatial connection is analyzed. The results indicate that the horizontal gradient of accessibility of different regions in China has statistical differences and the time-space compression caused by the layout of main transportation lines in Gansu province presents a typical “corridor effect.” The inter-provincial logistics economic relations in Gansu province demonstrate significant stratification characteristics and an unbalanced “neighbor effect” while there are few provincial groups directly connecting with Gansu province. Finally, based on data analysis and logical deduction, the paper analyzes the current situation, discusses the existing shortcomings and strategic advantages of Gansu province, and tries to give development suggestions in terms of the current opportunities as well as responsibilities.
