摘  要:绿色"一带一路"建设是"一带一路"倡议的重要组成部分,而贸易开放则是促进"一带一路"沿线国家绿色技术进步的重要渠道。本文用SBM模型测算了"一带一路"沿线国家的绿色全要素生产率,用以衡量沿线国家的绿色技术进步,并基于面板门槛模型从进口贸易和出口贸易两个角度考察了沿线国家贸易开放基于经济发展、基础设施、金融发展和制度质量4个因素的绿色技术溢出门槛效应。研究发现:(1)经济发展、基础设施、金融发展和制度质量四个变量对"一带一路"沿线31个国家贸易开放的绿色技术溢出都存在显著门槛效应。进口贸易的绿色技术溢出效应随着经济发展两个门槛的跨越而由负转正并逐步增强;在跨越基础设施、金融发展和制度质量门槛前后,进口贸易的绿色技术溢出效应都为正,但在跨越门槛之后进一步增强。出口贸易在样本期内对绿色全要素生产率呈负向影响,但影响程度随四个变量门槛的跨越而逐渐降低,显著性水平也有所下降。(2)沿线国家基于四个门槛变量的通过情况有所不同。跨越基础设施水平门槛和金融发展水平门槛的样本国家较多,跨越制度质量水平门槛的国家次之,跨越经济发展水平门槛的样本国家还较少。(3)贸易开放整体有利于"一带一路"沿线国家绿色全要素生产率的提高,相比出口贸易,进口贸易更有助于促进"一带一路"国家绿色技术进步。因此,在"一带一路"倡议框架下逐步提升沿线国家在此四方面的发展水平将有利于绿色技术溢出效应的充分显现。The building of‘Green Belt and Road’is an important part of‘the Belt and Road’(B&R)initiative,while trade openness is a crucial channel to promote green technological progress of countries along‘B&R’.This paper adopts SBM model to calculate the green total-factor productivity(TFP),to measure green technological progress of countries along‘B&R’,and to investigate the threshold effect of trade openness’s green technology spillover of 31 countries along‘B&R’based on a panel threshold model.The research results show that:①four factors including economic development,infrastructure,institution quality and financial development all have significant threshold effects on trade openness green technology spillover of sample countries.The green technology spillover effect of import trade transforms from negative to positive and gradually enhances with the crossing of two economic development thresholds;the green technology spillover effect of import trade is positive before crossing the thresholds of infrastructure,financial development and institution quality,but get further strengthened after crossing the thresholds.The export trade has a negative impact on the green TFP during the sample period,while the influence degree decreases gradually with the threshold crossing of four variables.②Sample countries demonstrate different threshold-crossing situations based on four threshold variables.There are more sample countries crossing the threshold of infrastructure and financial development,followed by those crossing the threshold of institution quality,while there are fewer countries crossing the threshold of economic development level.③The overall trade openness is conducive to improving green TFP of countries along‘B&R’,especially the import trade,which is more beneficial to green technological progress of sample countries compared with the export trade.Therefore,it will be helpful to fully induce green technology spillover effect by improving the level of those four aspects in countries along
