Change in the pattern of urban-rural economic circulation and optimization in the Jianghan Plain region
Urban-rural economic circulation is an important part of the macro economic circulation in China.Optimizing urban-rural economic circulation is a fundamental project for building a new development pattern.This study analyzed the connotation of urban-rural economic circulation from four dimensions:supply and demand relationship,industrial linkage,factor flow,and circulation carrier,and constructed an evaluation index system,taking 2010-2020 as the study period and the Jianghan Plain as the case study area.It comprehensively applied the entropy weighting method and the obstacle degree model to reveal the characteristics of change of the spatiotemporal pattern of urban-rural economic circulation in the study area,and explored the path of its optimization.The results show that:1)During the study period,the level of urban-rural economic circulation in the Jianghan Plain region was low but continued to grow unevenly.The composite and sub-dimensional indices(supply and demand relationship,industrial linkage,factor flow,and circulation carrier)of urban-rural economic circulation grew from 0.2164,0.0616,0.0534,0.0641,and 0.0373 to 0.4095,0.1308,0.0850,0.0990,and 0.0947,with an average annual growth rate of 8.92％,11.24％,5.93％,5.45％,and 15.35％,respectively.2)During the same period,the urban-rural economic circulation in the study area generally showed a low level of aggregation,regional differences increased slightly,and the spatial coefficient of variation increased from 0.2055 to 0.2126.The high-value areas of supply and demand relationship and circulation carrier index of the urban-rural economic circulation gradually aggregated to the main transportation arteries and the urban areas along the routes,and the spatial coefficient of variation decreased from 0.3166 and 0.5665 to 0.2636 and 0.4705,but the industrial linkage and factor flow spatial distribution characteristics were not as distinct.3)The obstacle degree of urban-rural economic circulation in the study area showed a decreasing trend year by year,and the sub-dimension obstacle degree ranked as industrial linkage(28.20％)＞circulation carrier(27.89％)＞factor flow(23.98％)＞supply and demand relationship(19.93％),and the top four indicator obstacle degree ranked as night-light index(11.23％)＞proportion of built-up area(10.79％)＞output value of agricultural services(10.65％)＞loan balance of financial institutions per unit of GDP(9.82％).4)The optimization of the urban-rural economic circulation in the Jianghan Plain region can be divided into three types and six sub-districts,including single obstacle type,double obstacle type,and triple obstacle type,and according to the different types of obstacles in each district,the appropriate development strategies for the optimization of the urban-rural economic circulation were proposed respectively.The results of this study can provide some theoretical guidance and practical inspiration for the development of urban-rural economic circulation in the new era.
