黄河流域数字经济对乡村振兴的影响

Research on the Impact of Digital Economy on RuralRevitalization in the Yellow River Basin

选取黄河流域9省(区)2008—2020年的面板数据,构建数字经济和乡村振兴的评价指标体系,利用熵值法测算出数字经济和乡村振兴发展水平,基于金融发展的中介视角,运用固定效应模型,实证分析了黄河流域数字经济对乡村振兴的影响。研究结果表明,黄河流域数字经济能显著促进乡村振兴,此外,财政支出、企业数量、教育水平和产业结构也会影响乡村振兴的发展,其中财政支出的影响相对更强;金融发展在数字经济对乡村振兴的影响中起部分中介作用,在总效应中占比为48.8%,是促进乡村振兴的有效路径,这一结论也通过了稳健性检验。进一步研究发现,数字经济对黄河上游地区乡村振兴的促进作用明显大于中下游地区,金融发展水平在上游地区充当的是部分中介作用,在中下游地区却是完全中介作用。为全面提升黄河流域乡村振兴发展水平,应加强乡村数字基础设施建设,完善乡村金融体制建设以及加大财政支出力度。

According to the panel data of 9 provinces(autonomous regions)in the Yellow river basin from 2008 to 2020,the evaluation index system on digital economy and rural revitalization is constructed and the entropy method is used to calculate the development level of digital economy and rural revitalization.Based on the intermediary perspective of financial development,this paper empirically analyzes the impact of digital economy on rural revitalization in the Yellow river basin by the fixed effect model.The research results show that the digital economy in the Yellow river basin can significantly promote rural revitalization.In addition,financial expenditure,the number of enterprises,the level of education and industrial structure will also affect the development of rural revitalization,among which the impact of financial expenditure is relatively stronger;Financial development plays a part of intermediary role in the impact of digital economy on rural revitalization,accounting for 48.8%of the total effect.It is an effective way to improve rural revitalization,and this conclusion has also passed the robustness test.Further research shows that the digital economy plays a greater role in promoting rural revitalization in the upper reaches of the Yellow river than in the middle and lower reaches.The level of financial development acts as a partial intermediary in the upper reaches,but a complete intermediary in the middle and lower reaches.In order to comprehensively upgrade the development level of rural revitalization in the Yellow river basin,rural digital infrastructure construction should be strengthened,rural financial system construction should be accelerated and financial expenditure should be increased.
