摘要:

增强干旱地区数字经济与农业绿色发展的耦合协调度是促进农业高质量发展的必然要求。为探究干旱区数字经济与农业绿色发展的耦合协调情况,选取2011—2020年新疆区域面板数据,采用耦合协调模型测算新疆数字经济和农业绿色发展的耦合协调度,运用Kernel密度估计、标准差椭圆与Dagum基尼系数等方法对二者耦合协调度的时空演变进行分析。结果表明:(1)新疆数字经济呈现出“中心高、四周低”态势,农业绿色发展呈现“北高南低、东高西低”态势;2011—2020年新疆数字经济涨幅高达131.618%,农业绿色发展涨幅为33.922%。(2)新疆整体二者耦合协调度表现出随时间推移逐渐上升趋势,分区域增长幅度表现为:东疆>北疆>南疆;依据Kernel密度结果可知,无论是新疆整体还是三大区域都存在一定的极化效应特征;依据标准差椭圆可知,2011年至2015年,方位角上升1.747°,2015年至2020年方位角下降1.410°,数字经济和农业绿色发展的耦合协调度分布重心呈现出来回摆动的移动轨迹。(3)耦合协调度整体水平差异呈现出一定的收敛趋势,组间差异均值为0.403,组内差异均值为0.304。

Abstract:

Enhancing the coupling and coordination between the digital economy and green development of agriculture in arid areas is essential for promoting high-quality agricultural growth. This study explores the coupling and coordination between the digital economy and green development of agriculture in Xinjiang, China, using panel data from 2011 to 2020. A coupling and coordination model was employed to quantify the interactions between the digital economy and green development of agriculture. Methods including Kernel density estimation, standard deviation ellipse, and the Dagum Gini coefficient were utilized to analyze the spatiotemporal evolution of the coupling and coordination degree. The results indicate that: (1) Xinjiang’s digital economy exhibits a “high in the center, low in the surrounding areas” pattern, while green development of agriculture shows a “high north, low south, high east, low west” distribution. Between 2011 and 2020, the growth rate of the digital economy in Xinjiang reached 131.618%, whereas the green development of agriculture increased by 33.922%. (2) The overall degree of coupling coordination in Xinjiang shows a gradual upward trend, with the growth rate of sub-regions ranked as follows: east Xinjiang>north Xinjiang>south Xinjiang. The Kernel density results suggest a polarization effect in both Xinjiang as a whole and within its three major regions. Analysis using the standard deviation ellipse reveals that the azimuthal angle rose by 1.747° from 2011 to 2015, and fell by 1.410° from 2015 to 2020, indicating a back-and-forth oscillation in the center of gravity for the distribution of the digital economy and green development of agriculture. (3) The overall level difference in coupling coordination shows a convergence trend, with an average inter-group difference of 0.403 and an intra-group difference of 0.304.
