摘要 基于2011—2021年中国276个城市的数据,以跨境电商综合试验区作为准自然实验,运用双重差分模型探讨数字贸易对城市减污降碳协同发展的影响效应和作用机理。研究发现:数字贸易可以促进城市减污降碳协同发展,且通过了一系列稳健性检验;机制分析发现,数字贸易通过对数字服务业与跨境贸易企业的集聚和对传统要素与新型要素配置的优化来促进城市减污降碳协同发展;异质性分析表明,数字贸易对大城市、环境保护重点城市和非老工业基地城市减污降碳协同发展的促进作用更加显著;进一步分析表明,数字贸易对城市减污降碳协同发展产生了显著的正向空间溢出效应,主要通过跨境贸易企业集聚与创新要素配置来实现。研究结论为中国发展数字贸易、增强城市碳污协同治理提供了理论参考。

Abstract: Based on data from 276 cities in China from 2011 to 2021, this study employs a quasi-natural experiment using cross-border e-commerce comprehensive pilot zones and applies a difference-in-differences model to investigate the impact and mechanisms of digital trade on the synergistic development of urban pollution reduction and carbon emission reduction. The study shows that digital trade can promote the coordinated development of urban pollution reduction and carbon emission reduction, and has passed a series of robustness tests. Mechanism analysis reveals that digital trade fosters the coordinated development of urban pollution reduction and carbon emission reduction by agglomerating the digital service industry and cross-border trade enterprises, and by optimizing the allocation of traditional and new factors. Heterogeneity analysis indicates that the role of digital trade in promoting the coordinated development of urban pollution reduction and carbon emission reduction is more significant in large cities, key environmental protection cities and non-old industrial base cities. Further analysis shows that digital trade has a significant positive spatial spillover effect on the coordinated development of urban pollution reduction and carbon emission reduction, mainly realized through the agglomeration of cross-border trade enterprises and the allocation of innovative factors. This research provides theoretical references for China's development of digital trade and the enhancement of urban carbon-pollution synergistic governance.
