数字经济与农业现代化耦合协调时空演化研究

Study on Spatio-Temporal Evolution of Coupling Coordination between Digital Economy and Agricultural Modernization

论文基于2013—2020年全国30个省份数字经济和农业现代化的面板数据,建立复合系统综合评价指标体系,运用熵权法、耦合协调度模型、相对发展度模型、空间自相关模型分析其耦合协调发展水平。结果表明:我国数字经济、农业现代化水平以及数字经济—农业现代化耦合协调度均呈逐年上升趋势,但存在显著的区域异质性,数字经济水平以及数字经济—农业现代化耦合协调度呈现东部>中部>东北>西部的趋势,农业现代化水平呈现东部>东北>中部>西部的趋势;我国数字经济与农业现代化发展不平衡,多数省份数字经济水平滞后于农业现代化水平;空间自相关结果表明我国数字经济和农业现代化耦合协调发展存在较强的空间集聚和空间相关特征,东部地区空间联动格局较高。因此,我国应探索差异化地区数字经济推广的方案和策略,发挥发达地区的辐射作用,推动区域协调发展。

Based on the panel data of digital economy and agricultural modernization in 30 provinces and cities from 2013 to 2020,the comprehensive evaluation index system of composite system was established,and the coupled and coordinated development level was analyzed by entropy weight method,coupling and coordination degree model,relative development degree model and spatial autocorrelation model.The results show that China’s digital economy,agricultural modernization level and digital economyagricultural modernization coupling coordination degree are increasing year by year,but there is significant regional heterogeneity.The digital economy level and digital economy-agricultural modernization coupling coordination degree show the trend of east>middle>northeast>west,and the agricultural modernization level shows the trend of east>northeast>middle>west.The development of digital economy and agricultural modernization in China is unbalanced,and the level of digital economy in most provinces lags behind the level of agricultural modernization;The results of spatial autocorrelation show that the coupling and coordinated development of digital economy and agricultural modernization in China has strong spatial agglomeration and spatial correlation characteristics,and the spatial linkage pattern in the eastern region is higher.Therefore,China should explore the scheme and strategy of digital economy promotion in differentiated regions,give full play to the radiation effect of developed regions and promote regional coordinated development.
