摘要
使用2000−2019年1884个中国县域面板数据,将电子商务进农村综合示范政策视作政府支持农村电商发展的一项准自然实验,基于卫星反演技术获取农业生态环境质量数据刻画农村地区“绿水青山”状况,采用多期双重差分模型评估了农村电商发展对农业生态环境质量的影响效应,并进一步探究其作用机制和异质性效应。结果表明:农村电商发展显著提高农业生态环境质量,具有明显的“绿水青山”效应,且这一效应在长期内可持续。经过平行趋势、安慰剂、PSM-DID等一系列检验,结果依然稳健。机制分析结果表明,农村电商发展通过推动农业绿色生产、提高农村信息化程度从而提高农业生态环境质量。进一步分析表明,农村电商发展的“绿水青山”效应在平缓地势地区、年降水量200毫米以上和非贫困县地区更加显著。因此,政府应持续推进农村电商的试点政策、强化优质绿色农产品品牌建设、提高农业生产者的数字素养、因地制宜制定农村电商发展策略,以实现经济效益、社会效益和生态效益的共赢。
Using panel data covering 1884 Chinese counties from 2000 to 2019 and considering the comprehensive demonstration policy for E-commerce in rural areas as a quasi-natural experiment supported by the government to promote the development of rural e-commerce,this study characterizes the“lucid water and lush mountains”condition in rural areas by employing satellite inversion technology to obtain data on agricultural ecological environment quality.The time-varying difference-in-differences(DID)model is used to assess the impact of rural e-commerce development on agricultural ecological environment quality,while further exploring its mechanism and heterogeneity effect.The results indicate that rural e-commerce development significantly improves the agro-ecological environment quality,demonstrating a significant“lucid water and lush mountains”effect that is sustainable over the long term.Robustness checks,including parallel trend test,placebo test,and PSM-DID test,confirm the stability of the results.Mechanism analysis presents that rural e-commerce development improves the agroecological environment quality by promoting green agricultural production and enhancing the degree of informatization in rural areas.Further analysis shows that the“lucid water and lush mountains”effect of rural e-commerce development is more pronounced in areas with gentle terrain,annual precipitation exceeding 200 millimeters,and non-poor counties.Therefore,the government should continue to advance the pilot policies for rural e-commerce,strengthen the branding of high-quality green agricultural product,enhance the digital literacy of agricultural producers,and formulate rural e-commerce development strategies tailored to local conditions,so as to achieve a win-win situation in terms of economic,social,and ecological benefits.
