数字赋能绿色出口的异质动态效应研究

Research on the heterogeneous dynamic effects of green export empowered by digital

如何有效发挥数字赋能绿色出口效应是“双碳”目标下中国实现由贸易大国转向贸易强国的关键。以2009—2017年中国省级面板数据为样本,同时以2009—2021年国家层面数据为补充,通过构建面板门槛模型实证考察数字赋能绿色出口的异质动态效应。结果表明,中国数字赋能绿色出口效应呈现出一个由弱到强的动态演变过程,该效应在中国东部地区表现明显,但在中国中西部地区却不存在动态特征;相比非污染密集型行业,数字赋能绿色出口效应的动态特征在污染密集型行业表现更显著。在进一步分析数字赋能绿色出口效应的异质动态约束机制后发现,地区经济发展水平、绿色技术创新、贸易开放度和能源生产结构是约束数字赋能绿色出口效应的重要因素。新时代下,中国应持续加强新型基础设施建设,推动数字技术与绿色贸易融合发展,同时着力提高地区经济发展水平、加大绿色技术创新、优化能源生产结构,在持续扩大对外开放的大背景下打好政策“组合拳”,以充分发挥数字赋能绿色出口效应的作用。

How to effectively exert the effect of green export empowered by digital is the key for China to realize the transformation from a large trading nation to a strong trading nation under the dual carbon goals.This paper takes China’s provincial panel data from 2009 to 2017 as samples,supplemented by national data from 2009 to 2021,to empirically examine the heterogeneous dynamic effects of green export empowered by digital through constructing a panel threshold model.The results show that the green export empowered by digital in China presents a dynamic evolution process from weak to strong.This effect is obvious in the eastern region of China,but there is no dynamic characteristic in the central and western regions of China;Compared with nonpollution-intensive industries,the dynamic characteristics of green export empowered by digital are more significant in pollution-intensive industries.After further analysis of the heterogeneous dynamic constraint mechanism of the green export empowered by digital,it is found that regional economic development level,green technology innovation,trade openness and energy production structure are important factors to constrain the effect of green export empowered by digital.In the new era,China should continue to strengthen the construction of new infrastructure,promote the integration of digital technology and green trade,and at the same time strive to improve the level of regional economic development,increase green technology innovation,optimize the energy production structure,and make a“winning combo”of policy in the context of continuously expanding the opening up to fully use the role of green export empowered by digital.
