摘要
城乡经济循环是国内大循环的重要构成部分,畅通城乡经济循环是构建新发展格局的基础工程。论文从供需关系、产业链接、要素流动和循环载体4个维度解析城乡经济循环内涵、构建测度指标体系,并以2010—2020年为研究期、江汉平原为案例区,综合运用熵权法和障碍度模型,揭示江汉平原城乡经济循环时空格局演变特征,探寻其畅通优化路径。结果表明:①研究期内江汉平原城乡经济循环水平较低但持续非均衡增长,城乡经济循环综合指数及供需关系、产业链接、要素流动和循环载体4个分维度指数分别从0.2164、0.0616、0.0534、0.0641和0.0373增长到0.4095、0.1308、0.0850、0.0990和0.0947,年均增长率分别为8.92%、11.24%、5.93%、5.45%和15.35%。②同期江汉平原城乡经济循环总体呈低水平聚集、区域差异小幅增大,空间变异系数由0.2055增长为0.2126。城乡经济循环供需关系和循环载体分维指数高值区逐渐向主要交通干线及沿线城市地区聚集、空间变异系数分别由0.3166、0.5665减小到0.2636、0.4705,但产业链接和要素流动空间分布特征不甚显著。③江汉平原城乡经济循环障碍度呈逐年下降态势,分维度障碍度排序为产业链接(28.20%)>循环载体(27.89%)>要素流动(23.98%)>供需关系(19.93%),分指标障碍度排序前四为夜间灯光指数(11.23%)>建成区面积比例(10.79%)>单位GDP农业服务业产值(10.65%)>单位GDP金融机构贷款余额(9.82%)。④江汉平原城乡经济循环畅通优化可分为单一障碍型、双重障碍型和三重障碍型等3种类型6个分区,根据各区不同障碍类型分别提出针对性城乡经济循环畅通优化发展策略。研究结果可为新时期城乡经济循环发展提供理论借鉴和实践启示。
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.
