贸易便利化对企业能源消耗强度的影响研究——基于“一带一路”背景下中欧班列的准自然实验

A Study of The Impact of Trade Facilitation Policies on the Energy Consumption Intensity of Enterprises--A Quasi-natural Experiment Based on the China-Europe Liner in the Context of the Belt and Road

在中国生态文明建设背景下,企业能源消耗强度是衡量企业可持续发展水平的重要标准。基于2010~2023年中国A股上市公司数据,本文将中欧班列的开通视作准自然实验,运用多期双重差分模型研究贸易便利化对企业能源消耗强度的影响及内在机制。研究发现,贸易便利化显著降低了企业的能源消耗强度。机制分析表明,贸易便利化对企业能源消耗强度的抑制通过企业科技创新效应和优化资源配置来发挥作用。异质性分析发现,在私有企业、普通污染企业及中部企业中,贸易便利化对能源消耗强度的抑制作用更加显著。本文丰富了贸易便利化政策的经济效应研究,为企业可持续发展提供了一定的理论参考。

In the context of China's ecological civilisation construction,corporate energy consumption intensity is an important criterion to measure the level of corporate sustainable development.Based on the data of China's A-share listed companies from 2010 to 2023,this paper treats the opening of the China-Europe liner train as a quasi-natural experiment,and applies a multi-period double-difference model to study the impact of trade facilitation on the energy consumption intensity of enterprises and the intrinsic mechanism.It is found that trade facilitation significantly reduces the energy consumption intensity of enterprises.The mechanism analysis shows that trade facilitation suppresses the energy consumption intensity of enterprises through the effect of technological innovation and optimal resource allocation.Heterogeneity analysis reveals that the suppression effect of trade facilitation on energy consumption intensity is more significant in privately-owned enterprises,ordinary polluting enterprises and central enterprises.This paper enriches the research on the economic effects of trade facilitation policies and provides certain theoretical references for the sustainable development of enterprises.
