自2016年G20峰会首次提出“数字经济”概念以来，数字经济已深入渗透至三大产业，与各领域广泛融合。其兴起与发展为城乡融合发展带来新的机遇与方向，如何有效利用数字经济推动城乡融合成为当前社会的重要议题之一。四川省作为我国西部地区发展较为突出的省份，为西部地区城乡融合与数字经济发展提供了良好的示范，但在发展过程中仍面临诸多挑战。因此，对四川省数字经济与城乡融合的发展状况进行测度，并探究二者之间的关系，对于西部地区实现城乡融合具有重要的参考价值。本文选取2011-2022年四川省21个市州的统计数据，采用熵值法对四川省城乡融合发展水平及数字经济发展状况进行测算，深入剖析数字经济对城乡融合的影响。首先，本文详细阐述研究背景与意义，梳理相关文献，确定研究内容与研究方法。其次，对数字经济与城乡融合发展的概念进行界定，并整理相关理论。接着，构建数字经济与城乡融合发展的指标体系，收集相关数据，运用熵值法进行测度，分析二者的时空演变特征。然后，本文采用面板固定效应模型探究四川省数字经济与城乡融合发展之间的关系，并进一步探索产业合理化在其中发挥的中介作用。最后，总结研究结果，并提出相应的政策建议。

研究结果表明：第一，四川省数字经济与城乡融合发展呈波动式上升态势。全省21个市州的数字经济与城乡融合发展水平均提高，但区域间仍表现出明显差异。成都市处于领先地位，而阿坝、甘孜和凉山三个自治州相对落后，具有较大的发展潜力。第二，四川省四大经济区之间及经济区内部的数字经济与城乡融合发展存在显著差距。通过Dagum基尼系数分析可知，区域间的差异是造成四川省数字经济与城乡融合发展不平衡的主要原因，经济区内部的差异同样对全省整体城乡融合发展的不均衡性产生了影响。第三，四川省数字经济发展显著推进了城乡融合发展的进程。总体检验结果表明，数字经济有效推动城乡融合的发展；分区域检验进一步表明，数字经济对成都平原经济区等展现出更为强劲的促进作用，同时对非成都平原经济区的城乡融合发展也发挥了推动作用。第四，四川省数字经济影响产业合理化，进而影响城乡融合发展。数字经济发展促使四川省产业结构优化升级，调节四川省第一、二、三产业的发展比重，使产业结构趋于合理化，促进四川省基础设施建设和公共服务发展，进而提升城乡居民收入与消费，实现城乡融合发展的目标。通过深入分析，本文发现四川省城乡融合发展与数字经济发展虽已取得一定成效，但仍面临诸多挑战。针对四川省城乡融合发展与数字经济发展的现状，本文提出以下建议：政府发挥主导作用，促进四川省省内各市州协调发展，推动周边区域的协同进步，实现区域均衡发展；强化数字产业发展，带动传统产业数字化转型，推进城乡产业结构升级；依据区域比较优势探索差异化城乡融合发展路径，制定差异化政策，实现协调发展；加强人才培养，扩大人才储备，为数字经济与城乡融合发展提供人才储备。

Since the G20 Summit first proposed the concept of "digital economy" in 2016, it has deeply penetrated China's three major industries and achieved extensive integration across sectors. The rise and development of the digital economy presents new opportunities and directions for urban-rural integration. Effectively leveraging the digital economy to promote urban-rural integration has become a critical societal issue. As a prominent province in China's western region, Sichuan provides a valuable demonstration for digital economy development and urban-rural integration in western China, yet still faces multiple challenges. Therefore, measuring the development status of the digital economy and urban-rural integration in Sichuan, and exploring their relationship, holds significant reference value for advancing urban-rural integration in western regions.

This study utilizes statistical data from 21 prefecture-level cities and autonomous prefectures in Sichuan Province (2011-2022) to measure urban-rural integration levels and digital economy development through the entropy method, and systematically analyzes the impact of the digital economy on urban-rural integration. First, we elaborate on the research background, significance, and methodology through literature review. Second, we define core concepts and theoretical frameworks for digital economy and urban-rural integration. Subsequently, an indicator system is constructed, with data analyzed via entropy method to reveal spatiotemporal evolution patterns. Then, panel fixed-effects models are employed to examine the relationship between digital economy and urban-rural integration, while exploring the mediating role of industrial rationalization. Finally, policy recommendations are proposed based on research findings.

The research results show that: First, the development of digital economy and urban-rural integration in Sichuan Province has shown a fluctuating upward trend. The level of digital economy and urban-rural integration in all 21 prefectures and cities in the province has improved, but there are still significant differences among regions. Chengdu is in the leading position, while the three autonomous prefectures of Aba, Ganzi and Liangshan are relatively lagging behind and have great potential for development. Second, there are significant differences in the development of digital economy and urban-rural integration among the four major economic zones in Sichuan Province and within each economic zone. Through the analysis of the Dagum Gini coefficient, it is found that the differences among regions are the main cause of the imbalance in the development of digital economy and urban-rural integration in Sichuan Province, and the differences within each economic zone also have an impact on the overall imbalance of urban-rural integration in the province. Third, the development of digital economy in Sichuan Province has significantly promoted the process of urban-rural integration. The overall test results show that digital economy effectively promotes the development of urban-rural integration; the regional test further indicates that digital economy shows a stronger promoting effect on the Chengdu Plain Economic Zone and also plays a promoting role in the urban-rural integration of non-Chengdu Plain Economic Zone. Fourth, the development of digital economy in Sichuan Province affects the rationalization of industrial structure, and thus affects the development of urban-rural integration. The development of digital economy has promoted the optimization and upgrading of industrial structure in Sichuan Province, adjusted the development proportion of the first, second and third industries in Sichuan Province, made the industrial structure more rational, promoted the construction of infrastructure and the development of public services in Sichuan Province, and thus increased the income and consumption of urban and rural residents, achieving the goal of urban-rural integration. Through in-depth analysis, this paper finds that although the development of urban-rural integration and digital economy in Sichuan Province has achieved certain results, it still faces many challenges. In view of the current situation of urban-rural integration and digital economy development in Sichuan Province, this paper puts forward the following suggestions: The government should play a leading role, promote the coordinated development of all prefectures and cities in Sichuan Province, and promote the coordinated progress of surrounding areas to achieve regional balanced development; strengthen the development of digital industry, drive the digital transformation of traditional industries, and promote the upgrading of urban-rural industrial structure; explore differentiated paths for urban-rural integration based on regional comparative advantages, formulate differentiated policies, and achieve coordinated development; strengthen talent cultivation, expand talent reserves, and provide talent reserves for the development of digital economy and urban-rural integration.
