可持续贸易、绿色技术进步与全球创新链升级的交互作用--碳中和背景下跨国多行业的数据实证

The Interaction of Sustainable Trade,Green Technological Progress and the Upgrading of the Global Innovation Chain:Based on Data from Multinational and Multi-industry in the Context of Carbon Neutrality

受全球新型冠状病毒肺炎疫情以及单边贸易保护主义的影响,与经济发展密切相关的可持续贸易成为各国关注的焦点。以32个在世界经济体中具有代表性的国家和地区为例,根据其1995−2018年的相关面板数据,基于三阶段SBM-DEA模型,结合Malmquist指数测算创新效率,分析其与绿色技术进步对可持续贸易的影响,并利用空间杜宾模型等进行回归分析和效应分解。交互作用方面,结合空间杜宾、误差模型结果,综合考虑运用Bootstrap中介效应进行分析。结论表明:绿色技术进步在显著促进单一国家可持续贸易发展的同时,对周边地区或经济发展水平相近的地区具有积极的正向溢出效应;绿色技术进步对可持续贸易的作用会受到创新效率的正向影响。

Affected by the global COVID-19 pandemic and unilateral trade protectionism,sustainable trade,which is closely related to economic development has become the focus of attention everywhere.Taking 32 representative countries and regions in the world economy as examples,according to their relevant panel data from 1995 to 2018,based on the non-radial three-stage SBM-DEA model,combined with the Malmquist index,this paper measures innovation efficiency,and analyzes its relationship with the impact of green technology progress on sustainable trade.The spatial Durbin model is adopted for regression analysis and effect decomposition.In terms of interaction,combined with the results of the spatial Dobin and error models,the Bootstrap mediation effect was comprehensively considered for analysis.The result shows that the progress of green technology not only promotes the sustainable trade development of a single country,but also has a positive spillover effect on surrounding areas or areas with similar economic development levels.The effect of green technological progress on sustainable trade is positively affected by innovation efficiency.
