Mechanism of influence of accessibility on the evolution of the spatial pattern of producer services driven by transportation integration:A case study of the Yangtze River Delta region,China
Prospectively exploring the role of accessibility on the evolution of industrial space driven by transportation integration will provide a reference for industrial site selection,functional positioning,and the formulation of related policy systems.Taking the producer service industry in the Yangtze River Delta region as an example,this study constructed a spatial accessibility model to measure county accessibility values,and used GIS spatial analysis and spatial Durbin model to measure the intensity of the impact of accessibility on industrial spatial patterns and trends of change,which can reveal the mechanism of accessibility's effect on the spatial evolution of producer services driven by transportation integration.The results indicate that:1)In 2010 and 2020,the high-value areas and high-growth areas of producer services in all and sub-sectors showed hierarchical distribution and distribution near central cities.2)Driven by transportation integration,the accessibility level of cities in peripheral areas and core cities in the Yangtze River Delta region has been greatly improved.The accessibility pattern presents a flat core-periphery structure from east to west,which has direct effects and indirect effects on the spatial pattern of the producer service industry.Among the direct effects,comprehensive transportation accessibility has a stronger effect on the spatial pattern of producer services,and high-speed rail accessibility has a significant impact on the development pattern of producer services.In the indirect effects,accessibility has an important impact on the spatial pattern of producer services through factors such as spatial agglomeration,spatial competition,and market potential.3)The positive and negative effects of spatial agglomeration and spatial competition factors in neighboring counties on the spatial pattern of local producer service industries have increased.Market potential is the dominant factor in the location selection of producer service enterprises.Only when counties and districts have sufficient market potential can high-level accessibility play a key role in attracting producer service enterprises.4)Accessibility not only has the"centrifugal force"that promotes the proliferation of producer service industry enterprises,but also has the"centripetal force"that promotes the agglomeration of producer service industry enterprises.The two jointly affect the spatial location choices and relocation decisions of enterprises.Thus,faced with the increasing level of regional transportation integration,various regions can plan and locate producer service industrial clusters in transportation hub areas according to local conditions based on the sensitivity of different industries to accessibility and their location preferences.
