Influence Mechanism and Empirical Test of Digital Economy in Promoting Rural Industrial Integration

农村产业融合是实现乡村振兴的重要抓手，数字经济的发展对农村产业融合具有重要促进作用。文章从价值链视角出发，将农村产业融合划分为农业内部融合和农业与二三产业融合，构建了农村产业融合影响机制模型，并在此基础上运用固定效应面板回归模型和中介效应模型进行实证检验。结果表明，数字经济对农村三次产业融合发展具有显著的促进作用；技术市场发展和城镇化在数字经济促进农村产业融合发展过程中发挥显著的正向作用；区域间数字经济对农村三次产业融合发展影响具有异质性，中部地区的影响程度更大；高人力资本水平和高市场化水平的地区的数字经济对农村产业融合的促进作用更大。Rural industrial integration is an important hand in realizing rural revitalization, and the development of digital economy has an important role in promoting rural industrial integration. From the perspective of value chain, the article divides rural industrial integration into internal integration of agriculture and integration of agriculture and secondary and tertiary industries, constructs a model of the influence mechanism of rural industrial integration, and empirically tests it based on the use of fixed effect panel regression model and mediation effect model. The results show that the digital economy has a significant role in promoting the development of the integration of rural three industries; the development of the technology market and urbanization play a significant positive role in the process of the digital economy to promote the development of the integration of rural industries; the impact of the digital economy on the development of the integration of rural three industries is heterogeneous among regions, with a greater degree of impact in the central region; the digital economy in regions with high human capital levels and high marketization levels has a greater role in promoting rural industrial integration.
