数字服务贸易对出口隐含碳强度的影响研究——基于64个国家(地区)的面板数据

Research on the Impact of Digital Service Trade on the Embodied Carbon Intensity on Exports:Based on Panel Data of 64 Countries(Regions)

数字服务贸易作为一种新型贸易形式,凭借数字技术赋能的优势,为全球经济恢复增长注入了新动能。基于全球64个主要国家(地区)2010-2021年面板数据,运用双向固定效应模型探究数字服务贸易对出口隐含碳强度的影响以及背后的传导机制。研究结果表明:①数字服务贸易可以显著降低出口隐含碳强度;②数字服务贸易可以通过提高收入水平、优化贸易结构和促进技术创新来间接降低出口隐含碳强度;③在高收入、高数字服务贸易发展水平国家以及ICT信息通信服务部门的降碳效应更为明显。研究结论为世界各国制定相关数字服务贸易政策以及实现“双碳”目标提供了参考。

Digital service trade,as a new form of trade,has injected new momentum into the global economic recovery and growth with the advantages of digital technology empowerment.Based on panel data from 64 countries(regions)from 2010 to 2021,this study uses two-way fixed effects model to explore the impact of digital service trade on the implied carbon intensity of exports and the underlying transmission mechanism.The research results indicate that:①Digital service trade can significantly reduce the implied carbon intensity of exports.②Digital service trade can indirectly reduce the implied carbon intensity of exports by increasing income levels,optimizing trade structure,and promoting technological innovation.③The carbon reduction effect is more pronounced in high-income and high level of digital service trade development countries,as well as in service sectors such as ICT trade.The research findings provide a reference For countries around the world to formulate relevant digital service trade policies to achieve the“Dual Carbon”goals.
