摘要
在商贸流通业与国际贸易耦合机理的支持下,基于耦合协调度模型,采用核密度估计图、变异系数和空间自相关等方法实证研究2004-2016年中国大陆地区31个省市区两系统耦合协调发展的时空差异。研究发现:中国商贸流通业与国际贸易的综合发展水平和耦合度在空间上呈现自东向西层级递减的特点,在两系统的相对发展程度中东部以协同发展为主,而中西部则是国际贸易制约商贸流通业的发展;两系统耦合协调度提升缓慢,整体仍处于轻度失调和濒临失调之间,其核密度分布图逐渐向近似正态分布特征转变;整体耦合协调度的空间差异正由"大差距严重失调"向"小差距濒临失调"转变,其中东部显著缩小,中部微扩,而西部正不断拉大;耦合协调度在空间中存在显著的同类集聚特点,最终形成了以苏沪为核心的高-高集聚区和藏甘青新连片区的低-低集聚区。应加强商贸流通体系建设,合理配置国内外商贸资源,消除协调发展的体制壁垒和优化两系统耦合协调发展环境。
With the support of the coupling mechanism of the commercial circulation industry and international trade,based on the coupling coordination degree model,the paper uses the methods of coefficient of variation,nuclear density estimation map,and spatial auto-correlation to make an empirical research on the two system coupling degree and its spatial-temporal differences for the 31 provinces from 2004 to 2016 in China.The study shows that,firstly,the comprehensive development level and the coupling degree of China's commercial circulation industry and international trade show spatially decreasing features from the east to the west,and the relative development degree of the two systems is mainly coordinated development in eastern area,while the international trade restricts the development of commercial circulation in the central and western areas.Secondly,the coupling coordination degree of the two systems is slowly increasing,and it is still between slight discord and proximity disorder,which nuclear density distribution map gradually shifts to approximate normal distribution characteristics.Thirdly,the spatial difference of overall coupling coordination degree is changing from a“big disparity and serious discord”to“small disparity and proximity disorder”,in which,it is significantly reduced in the eastern region,slightly enlarged in the central region,and continuously widened in the western region.Fourthly,the degree of coupling coordination in the space has significant homogeneous agglomeration features,and finally forms high-high agglomeration area with Jiangsu-Shanghai as the core and a low-low agglomeration area with the Tibet-Gansu-Qinghai-Xinjiang contiguous area.Thus,we should strengthen the construction of the commercial circulation industry system,rationally allocate domestic and foreign trade resources,eliminate the institutional barriers to coordinated development,and optimize the coordinated development environment of the two systems.
