Study on the Coupling and Coordination of Digital Economy Development and Rural Revitalization in Gansu Province

在数字化浪潮与乡村振兴战略的双重背景下，甘肃省作为我国西北地区的重要省份，面临着诸多机遇与挑战。本文以甘肃省为研究对象，构建了数字经济与乡村振兴的指标体系，运用熵值法和耦合协调模型对其耦合协调度进行测度与分析。研究发现，2014~2023年甘肃省数字经济与乡村振兴的耦合协调度整体呈现上升趋势，从轻度失调逐渐向优质协调过渡。数字经济的发展为乡村振兴注入了新活力，而乡村振兴也为数字经济提供了广阔空间和应用场景。然而，两者之间的融合发展仍面临一些障碍，如数字基础设施不足、农村创新创业环境有待改善等。另外，通过灰色关联分析法，研究发现数字普惠金融指数、互联网宽带接入端口、农村居民人均可支配收入等指标对耦合协调度的贡献显著，而电信业务总量、城乡收入差距等指标的关联度较低。因此，建议进一步加强数字基础设施建设，推动农村产业融合发展，提升农村公共服务数字化水平，优化农村创新创业环境，以促进甘肃省数字经济与乡村振兴的协同发展，推动甘肃省农村经济高质量发展、社会全面进步以及生态环境可持续改善。Under the dual background of digital wave and rural revitalization strategy, Gansu Province, as an important province in the northwest of China, faces many opportunities and challenges. This paper takes Gansu Province as the research object, constructs the index system of digital economy and rural revitalization, and measures and analyzes its coupling coordination degree by using the entropy value method and the coupling coordination model. It is found that the coupling coordination degree of digital economy and rural revitalization in Gansu Province in 2014~2023 shows an overall upward trend, gradually transitioning from mild disorder to high-quality coordination. The development of digital economy injects new vitality into rural revitalization, while rural revitalization also provides broad space and application scenarios for digital economy. However, the integrated development between the two still faces some obstacles, such as insufficient digital infrastructure, rural innovation and entrepreneurship environment needs to be improved. In addition, through the gray correlation analysis method, it is found that indicators such as digital financial inclusion index, Internet broadband access ports, and per capita disposable income of rural residents contribute significantly to the degree of coordination of the coupling, while indicators such as the total amount of telecommunication business and the urban-rural income gap have a lower degree of correlation. Therefore, it is recommended to further strengthen the construction of digital infrastructure, promote the integrated development of rural industries, enhance the digitalization of rural public services, and optimize the environment for rural innovation and entrepreneurship, in order to promote the synergistic development of the digital economy and rural revitalization in Gansu Province, and to promote high-quality development of the rural economy, comprehensive social progress, and sustainable improvement of the ecological environment in Gansu Province.
