党的十九大报告指出，农业农村农民问题是关系国计民生的根本性问题，必
须始终把解决好“三农”问题作为全党工作的重中之重，实施乡村振兴战略。而
随着信息技术、互联网、大数据等的不断发展和扩散，经济社会的数字化程度不
断加深，人类社会已经进入数字化时代。其中，数字技术向乡村的快速延伸和渗
透，为促进数字经济与乡村振兴融合提供了契机。
本文以黄河流域九省（区）为研究区域，首先通过回顾并梳理相关国内外文
献，对数字经济和乡村振兴的概念和含义予以界定；其次，在已有理论的基础上
分析数字经济对乡村振兴的直接及间接影响机制；随后，利用 2008—2020 年乡
村振兴和数字经济的相关数据，构建评价指标体系，对黄河流域九省（区）的发
展水平进行测度和定量分析，并运用熵值法得到数字经济和乡村振兴综合指数；
再以金融发展作为中介变量，运用中介效应模型检验黄河流域九省（区）数字经
济对乡村振兴的间接传导路径；最后，在检验了数字经济与乡村振兴之间存在空
间关联性的基础上，构建空间杜宾模型，对数字经济影响乡村振兴的空间溢出效
应进行分析。
研究结果表明：黄河流域数字经济能显著促进乡村振兴，数字经济每增长1%，
乡村振兴增长 0.4272%；金融发展在数字经济对乡村振兴影响中起部分中介的作
用，是促进乡村振兴的有效路径；经过稳健性检验后结论依旧成立，进一步研究
发现，存在明显的区域异质性：黄河上游地区数字经济对乡村振兴的驱动作用远
远大于中下游地区；同时，空间杜宾回归结果显示，数字经济对乡村振兴的空间
溢出效应显著为正，即数字经济的发展不仅能促进本地区乡村振兴，也能带动周
边地区的乡村振兴发展。
最后，为进一步促进数字经济和乡村振兴持续稳定健康发展，提出了加强乡
村数字基础设施建设、完善乡村金融体制建设和积极推动黄河流域区域合作等政
策建议。

The report of the 19th National Congress of the Communist Party of China pointed out that the problem of agricultural and rural farmers is a fundamental problem related to the national economy and the people's livelihood. We must always take solving the problem of "agriculture, rural areas and farmers" as the top priority of the Party's work and implement the strategy of rural revitalization. With the continuous development and diffusion of information technology, the Internet, big data, etc., the degree of digitalization of the economic society continues to deepen, and human society has entered the digital era. Among them, the rapid extension and penetration of digital technology into rural areas provides an opportunity to promote the integration of digital economy and rural revitalization.

This paper takes nine provinces (regions) in the Yellow River basin as the research area. First, by reviewing and combing the relevant domestic and foreign literature, it defines the concept and meaning of digital economy and rural revitalization; Secondly, on the basis of existing theories, it analyzes the direct and indirect influence mechanism of digital economy on rural revitalization; Then, using the relevant data of rural revitalization and digital economy from 2008 to 2020, an evaluation index system was built to measure and quantitatively analyze the development level of nine provinces (regions) in the Yellow River basin, and the comprehensive index of digital economy and rural revitalization was obtained by using entropy method; Then, taking financial development as the intermediary variable, the indirect transmission path of digital economy to rural revitalization in nine provinces (regions) of the Yellow River basin is tested by using the intermediary effect model; Finally, on the basis of testing the spatial correlation between digital economy and rural revitalization, a spatial Dubin model is constructed to analyze the spatial spillover effect of digital economy on rural revitalization.

The results show that the digital economy in the Yellow River basin can significantly promote rural revitalization. For every 1% increase in digital economy, rural revitalization will increase by 0.4272%; Financial development plays a part of intermediary role in the impact of digital economy on rural revitalization, which is an effective path to promote rural revitalization; After the robustness test, the conclusion is still valid. Further research shows that there is obvious regional heterogeneity: the driving role of digital economy in the upper reaches of the Yellow River is far greater than that in the middle and lower reaches of the Yellow River; At the same time, the spatial Dubin regression results show that the spatial spillover effect of digital economy on rural revitalization is significantly positive, that is, the development of digital economy can not only promote rural revitalization in this region, but also promote rural revitalization in surrounding areas.

Finally, in order to further promote the sustainable, stable and healthy development of the digital economy and rural revitalization, policy recommendations were put forward, such as strengthening the construction of rural digital infrastructure, improving the rural financial system and actively promoting regional cooperation in the Yellow River basin.
