Research On The Coupling And Coordinated Development Of Digital Economy And Rural Revitalization In Southwest Chin

“If the countryside prospers,the country prospers”.The rural revitalization strategy is an overall and historic task related to the comprehensive construction of a modern socialist country.With the rapid development of the Internet,the digital economy has not only become the main driving force for global economic development,but also gradually penetrated into various fields of agriculture and rural areas,bringing good development opportunities for rural revitalization.On the one hand,the development of digital economy can effectively promote the comprehensive revitalization of rural areas,and on the other hand,the implementation of rural revitalization strategy gives a broader growth space for the development of digital economy.The interaction between the two and the close connection,and their coordinated development has become an important part of building digital villages and building digital China.This article takes four provinces(cities)in the southwest region of Yunnan,Guizhou,Sichuan,and Chongqing as the research object,based on the theory of urban-rural integration development,and the theory of transforming traditional agriculture.It constructs an evaluation index system for digital economy and rural revitalization from eight aspects: digital infrastructure,digital economic environment,digital life services,industrial prosperity,ecological livability,rural civilization,effective governance,and affluence.It uses entropy method,coupling coordination model,and barrier model,The paper analyzes and studies the level of digital economy and rural revitalization development in four provinces and cities in southwest China,the coupling and coordination relationship between the two systems,and obstacles.The main conclusions are as follows:(1)During the period from 2011 to 2020,the development level of the digital economy in southwest China has shown a continuous upward trend.The average level of digital economy development in the four provinces(cities)of Yunnan,Guizhou,Sichuan,and Chongqing has increased from 0.1521 in 2011 to 0.5836 in 2020,with a growth rate of 283.69%;The level of rural revitalization and development has shown a steady improvement.The average level of rural revitalization and development in the four provinces(cities)of Yunnan,Guizhou,Sichuan,and Chongqing has increased from 0.3368 in 2011 to 0.6362 in 2020,with an increase rate of 88.9%.Overall,the level of rural revitalization and development is significantly higher than the level of digital economy development,but the gap is gradually narrowing in evolution.This development trend is increasingly conducive to the coupling system moving towards a higher level.(2)During the period from 2011 to 2020,the average coupling degree between the digital economy and rural revitalization in Southwest China increased from 0.8480 to 0.9870,indicating that the two systems have a high degree of correlation and have reached a high-level coupling development stage.In terms of coupling coordination degree,the average coupling coordination degree in Southwest China increased from0.4512 in 2011 to 0.7711 in 2020,experiencing a development process from near imbalance to moderate coordination,from a type of imbalance decline to a type of coordination improvement.From the perspective of each province,Sichuan Province is the first to enter the high-quality coordination level,Guizhou Province and Yunnan Province are at the moderate coordination level,and Chongqing City is at the mild coordination level.(3)According to the diagnosis of obstacle factors,it is found that the obstacle degree of the digital economy subsystem in southwest China is significantly lower than that of the rural revitalization subsystem during the period 2011-2020,indicating that the rural revitalization subsystem has a significant impact on the coupling and coordinated development of southwest China.In terms of specific indicators,indicators such as the income gap ratio between urban and rural residents,the coverage rate of villagers’ committees,the coverage rate of cultural and entertainment facilities in towns and townships,rural production efficiency,agricultural meteorological observatories,and the penetration rate of rural computers are important obstacles to the coordinated development of the coupling of the digital economy and rural revitalization,and the influencing factors that restrict the coordinated development of the coupling of the digital economy and rural revitalization in various provinces(cities)are both consistent and have certain differences.Finally,based on the previous theoretical and empirical analysis,suggestions are proposed to promote the coordinated development of the digital economy and rural revitalization in southwest China from the perspectives of coordinating urban and rural informatization construction,optimizing policy resource allocation,strengthening informatization talent cultivation,and exploring diversified development models.
