摘要
新时代背景下,中国正在探索如何迈向内涵式、集约型、绿色化的高质量发展道路,而我们认为当下迅猛发展的电子商务或许可以成为其中一个重要突破口。文章以国家电子商务示范城市建设的准自然实验为切入点,运用多期双重差分法考察了国家电子商务示范城市建设对城市绿色高质量发展的影响及其作用机制。研究发现,与非国家电子商务示范城市相比,国家电子商务示范城市建设显著地促进了城市绿色高质量发展;通过更换估计方法和剔除部分样本等一系列稳健性检验,文章结果依然稳健可靠;为尽可能地解决样本选择性偏误和遗漏变量等内生性问题,我们还采用工具变量方法、PSM-DID方法和安慰剂检验等识别策略,发现结论依然成立。进一步研究发现,该正向促进作用在大型城市和资源型城市样本中更为显著。通过作用机制检验发现,国家电子商务示范城市主要通过产业结构升级效应、经济集聚效应和交易成本降低效应三个作用渠道促进城市绿色高质量发展。文章的研究结论具有明确的政策含义,为国家电子商务示范城市政策的实施提供了丰富的经验证据,对相关政府部门工作具有一定的指导性和参考价值。
Based on the quasi-natural experiment of national e-commerce demonstration cities,this paper studies the influence of the construction of national e-commerce demonstration cities on the green and high-quality development of the city and its mechanism by using the"progressive"DID method.It is found that compared with non-state e-commerce demonstration cities,the construction of national e-commerce demonstration cities significantly promotes the green and high-quality development of cities.We also adopt identification strategies such as instrumental variable method,PSM-DID method and placebo test,and find that the conclusions are still valid.Further research shows that the positive promotion effect is more significant in the samples of large-sized cities and resource-based cities.It is found that national e-commerce demonstration cities promote the green and high-quality development of the city mainly through the three channels of industrial structure upgrading effect,economic agglomeration effect and transaction cost reduction effect.This paper has three main contributions:Firstly,from the perspective of e-commerce development,it examines the impact of national e-commerce demonstration city construction on green and high-quality development for the first time,and expands and deepens the existing academic literature on green development and environmental pollution factors.Secondly,it evaluates the policy effect and mechanism of China’s e-commerce demonstration cities from the perspective of urban green and high-quality development,verifies that the construction of national e-commerce demonstration cities has a promoting effect on the green and high-quality development of cities,and provides empirical guidance for the further promotion and improvement of this type of urban development model.Thirdly,it adopts the identification strategy of the post stations in the Ming Dynasty and the number of telephone sets per 10,000 people in 1984 as instrumental variables,which is helpful to effectively identify the causal rel
