山东省商贸流通业与城乡一体化的关系

The relationship between commercial circulation industry and urban-rural integration in Shandong Province

为研究山东省商贸流通业与城乡一体化间的耦合协调关系,从市场环境和业态规模2个维度构建商贸流通业的评价指标体系,从经济发展、社会发展和空间环境3个维度构建城乡一体化的评价指标体系,以山东省2012—2021年的指标数据为样本,分析山东省商贸流通业与城乡一体化的关系。将熵权法与逼近理想解排序(technique for order preference by similarity to ideal solution,TOPSIS)法相结合计算指标权重,确定二者的发展指数,采用协整检验模型验证二者间的协整关系,以综合评价指数建立耦合协调度模型定量研究二者间的耦合协调关系,通过灰色关联度模型分析二者指标的关联度,确定影响二者耦合协调关系的关键因素。结果表明:城乡一体化水平每上升1个单位,商贸流通业的发展指数增大0.867个单位;2012—2021年山东省商贸流通业与城乡一体化间存在较强的耦合关系,耦合协调度从严重失调调整到优质协调;山东省商贸流通业和城乡一体化整体的灰色关联度较高。通过政策倾斜、资金扶持等措施加大资源要素投入,完善乡村基础设施,改善商贸流通业发展环境,搭建城乡商贸一体化发展体系,促进商贸流通业和城乡一体化的良性互动。

In order to study the coupling and coordination relationship between commercial circulation industry and urban-rural integration in Shandong Province,an evaluation index system for the commercial circulation industry is constructed from two dimensions:market environment and business scale,and an evaluation index system for urban-rural integration is constructed from three dimensions:economic development,social development,and spatial environment.The index data from Shandong Province from 2012 to 2021 are used as samples to analyze the relationship between the commercial circulation industry and urban-rural integration in Shandong Province.The entropy weight method is combined with the technique for order preference by similarity to ideal solution(TOPSIS)method to calculate the index weight,determine the development index of the two,and use the cointegration test model to verify the cointegration relationship between the two.A comprehensive evaluation index is used to establish a coupling coordination degree model to quantitatively study the coupling coordination relationship between the two.The correlation degree of the two indicators is analyzed through the gray correlation degree model,and the key factors affecting the coupling coordination relationship between the two are determined.The results show that for every 1 unit increase in the level of urban-rural integration,the development index of the commercial circulation industry increases by 0.867 units;from 2012 to 2021,there is a strong coupling relationship between the commercial circulation industry and urban-rural integration in Shandong Province,and the coupling coordination degree has been adjusted from serious imbalance to high-quality coordination;the overall gray correlation between the commercial circulation industry and urban-rural integration in Shandong Province is relatively high.By increasing resource input through policy tilt,financial support and other measures,improving rural infrastructure,improving the development environment of the commercial circulation industry,building an integrated development system of urban and rural commerce,and promoting the benign interaction between the commercial circulation industry and urban-rural integration.
