摘　　要：数字基础设施作为数字化转型的重要支撑点,能否依托数字赋能推动绿色贸易发展是亟待研究的问题。文章使用APEC成员国2007—2021年面板数据,构建计量模型,考察数字基础设施对绿色贸易的影响效果、作用机制以及空间溢出效应,并进一步探究制度质量的调节效应。研究发现:数字基础设施能够推动绿色贸易发展,该结论在经过一系列稳健性检验后依然成立;产业结构升级和技术创新在数字基础设施提升绿色贸易过程中扮演着重要传导作用;数字基础设施不仅对本国绿色贸易发展起促进作用,而且对他国存在正向空间溢出效应,长期中呈现负向空间溢出效应但溢出效果较弱;数字基础设施对绿色贸易的正向影响在不同国家发展水平、不同贸易依存度和不同信息通信技术监管水平的异质性分析中均得到进一步验证,但在不同海运水平下存在差异。进一步发现,数字基础设施对绿色贸易的影响存在制度质量的非线性边际效应递减的正向促进效果。基于此,应继续加强数字基础设施建设,使其为绿色贸易发展数字赋能,并着力提升一国制度质量,为数字基础设施推动绿色贸易发展保驾护航。As an important support point for digital transformation,whether digital infrastructure can rely on digital empowerment to promote the development of green trade is an urgent issue that needs to be studied.The article uses panel data from APEC member countries from 2007 to 2021 to construct an econometric model,examining the impact,mechanism,and spatial spillover effects of digital infrastructure on green trade,and further exploring the moderating effect of institutional quality.Research has found that digital infrastructure can promote the development of green trade,and this conclusion still holds after a series of robustness tests.The upgrading of industrial structure and technological innovation play an important conductive role in promoting green trade in digital infrastructure.Digital infrastructure not only promotes the development of domestic green trade,but also has a positive spatial spillover effect on other countries.In the long run,it presents a negative spatial spillover effect,but the spillover effect is relatively weak.The positive impact of digital infrastructure on green trade has been further validated in the heterogeneity analysis of different levels of development,trade dependence,and information and communication technology regulation in different countries,but there are differences at different levels of maritime transportation.Furthermore,it is found that the impact of digital infrastructure on green trade has a positive promoting effect of diminishing non-linear marginal effects of institutional quality.Based on this,we should continue to strengthen the construction of digital infrastructure to empower the development of green trade,and focus on improving the quality of a country's system to safeguard the promotion of green trade through digital infrastructure.
