摘要
数字贸易发展对环境污染的影响作用是实现绿色高质量发展的关键问题。本文基于2011~2021年我国区域面板数据,利用熵值法对数字贸易和环境污染指数进行测度,并从理论和实证双重角度分析数字贸易发展对环境污染的影响及其作用机制。研究发现:数字贸易发展能够有效减少环境污染,经过内生性(2SLS)和稳健性检验后依然成立。作用机制显示,数字贸易通过提升科技发展水平和优化产业结构提高资源利用效率,从而降低环境污染。门槛效应分析表明数字贸易水平对环境污染的影响效应存在门槛值,随着数字贸易的进一步发展能够有效抑制环境污染。结构分析显示,不同分位数下数字贸易对环境污染的影响效果存在差异。异质性分析发现,数字贸易在降低环境污染方面存在数字贸易维度、时间维度、胡焕庸线等异质性特征。本文为我国的环境污染治理提供了实践依据,为促进我国绿色低碳发展具有重要意义。The role of the impact of digital trade development on environmental pollution is a key issue in realizing green high-quality development. Based on China’s regional panel data from 2011 to 2021, this paper utilizes the entropy value method to measure the digital trade and environmental pollution index, and analyzes the impact of digital trade development on environmental pollution and its functioning mechanism from both theoretical and empirical perspectives. It is found that digital trade development can effectively reduce environmental pollution, which still holds after endogeneity (2SLS) and robustness tests. The mechanism of action shows that digital trade improves the efficiency of resource utilization by upgrading the level of scientific and technological development and optimizing the industrial structure, thus reducing environmental pollution. Threshold effect analysis shows that there is a threshold value for the effect of digital trade level on environmental pollution, and the further development of digital trade can effectively inhibit environmental pollution. Structural analysis shows that there are differences in the effect of digital trade on environmental pollution under different quartiles. Heterogeneity analysis found that there are heterogeneous characteristics of digital trade in reducing environmental pollution, such as digital trade dimension, time dimension and Hu Huanyong line. This paper provides a practical basis for the management of environmental pollution in China, which is of great significance for promoting the green and low-carbon development of China.
