【摘要】 电子商务作为数字经济与实体经济深度融合的典范，成为赋能县域共同富裕发展的新动能。基于“电子商务进农村综合示范”的准自然实验，利用2010—2020年县域面板数据，运用多期DID模型系统考察电商下乡对县域共同富裕的影响效应与作用机制。研究发现，电商下乡对促进县域共同富裕具有显著正向影响，经过一系列稳健性检验后结论仍显著成立。异质性分析表明，电商下乡对县域共同富裕的影响呈“东部>中部>西部”的区域差异化特征，且这种影响在资源禀赋高的区域更显著。机制分析表明，电商下乡通过提高农业生产效率、提升科技创新水平、推动产业结构升级赋能了县域共同富裕的发展。进一步研究发现，电商下乡的共富效应具有显著的空间溢出效应。研究结论对优化农村电商下乡综合示范政策以及推动县域共同富裕目标实现具有重要的理论价值与实践指导价值。更多还原

【Abstract】 As a model of deep integration of the digital economy and the real economy, e-commerce has become a driving force for the development of common prosperity in counties. Based on China’s National Rural E-commerce Comprehensive Demonstration Project, this study used county panel data from 2010 to 2020 and a multi-period difference-in-differences model in a quasi-natural experiment to systematically examine the impact of e-commerce going to the countryside on the common prosperity of counties and the mechanism of this impact. The study found that e-commerce going to the countryside has a significant positive impact on promoting common prosperity in counties, and the results were still significant after a series of robustness tests. Heterogeneity analysis showed that the impact of e-commerce going to the countryside on the common prosperity of counties is characterized by regional differentiation(east>central>west), and this effect is more significant in regions with high resource endowments. Mechanism analysis revealed that e-commerce going to the countryside enables the common prosperity and development of counties by increasing agricultural production efficiency, improving the level of scientific and technological innovation, and promoting the upgrading of industrial structure. Further research determined that the co-prosperity effect of e-commerce going to the countryside has a significant spatial spillover effect. The research conclusions have important theoretical and practical guiding value for optimizing the National Rural E-commerce Comprehensive Demonstration Project and promoting common prosperity in counties.更多还原
