黄河流域粮食主产区数字经济与农业高质量发展的耦合协调研究

Study on the Coupling Coordination between Digital Economy and Agricultural High-Quality Development in the Main Grain Producing Areas of the Yellow River Basin

运用熵值法和耦合协调模型,选取黄河流域4个粮食主产区2016—2020年的数据,测算其数字经济与农业高质量发展水平及二者间的耦合度和耦合协调度,并结合基尼系数对分省区在数字经济发展和农业高质量发展方面的耦合协调度区域差距进行了评价。研究结论如下:(1)黄河流域粮食主产区整体的数字经济和农业高质量发展水平逐步提升,山东省数字经济发展和河南省农业高质量发展领先;(2)粮食主产区省域数字经济与农业高质量发展的耦合度高度关联,但耦合协调度整体处于初级协调阶段,分省区耦合协调性差异显著,河南省和内蒙古自治区的数字化发展水平较低;(3)空间基尼系数逐年下降,区域差异在缩小。为强化数字经济与农业高质量发展间的耦合协调,提出针对性的措施。

Using entropy method and coupling coordination model,this paper selects the data of four major grain producing areas in the Yellow River basin from 2016 to 2020,calculates the level of digital economic development and high-quality agricultural development,the coupling degree and coupling coordination between them,and evaluates the regional gap of coupling coordination in digital economic development and high-quality agricultural development by provinces and regions with Gini coefficient.The conclusions are as follows:(1)The overall level of digital economy and high-quality agricultural development in the main grain producing areas of the Yellow River basin has gradually improved,and the development of digital economy in Shandong Province and high-quality agricultural development in Henan Province take the lead.(2)The coupling degree between the provincial digital economy and high-quality agricultural development in the main grain producing regions is highly related,but the coupling coordination is in the primary coordination stage as a whole,with significant differences in the coupling coordination between provinces and regions.The level of digital development in Henan Province and Inner Mongolia Autonomous Region is low.(3)The spatial Gini coefficient is decreasing year by year,and the regional difference is narrowing.In order to strengthen the coupling and coordination between digital economy and high-quality agricultural development,targeted measures are proposed.
