摘　　要：本文利用2000-2019年中亚五国面板数据,建立门限回归模型实证检验了贸易开放对绿色全要素生产率的影响。首先从经济总量、基础设施、金融发展和制度质量四个方面提出了门限效应假设,再从进口贸易与出口贸易两个方面测算了影响贸易开放绿色技术溢出效应的门槛水平。结果表明:经济总量、基础设施、金融发展和制度质量对中亚五国对外贸易的绿色技术外溢都有显著的门限效应。相对于出口贸易,进口贸易对门限变量发生作用的门槛要求更低,进口对于中亚国家绿色技术进步的推动作用更大更显著。This paper empirically tests the impact of trade openness on green total factor productivity by building a threshold regression model using panel data of five Central Asian countries from 2000-2019.The paper first proposes the threshold effect hypothesis in four aspects:economic aggregation,infrastructure,financial development and institutional quality,and then measures the threshold level affecting the green technology spillover effect of trade opening in terms of both import trade and export trade.The results show that economic aggregation,infrastructure,financial development and institutional quality all have significant threshold effects on green technology spillovers from foreign trade of the five Central Asian countries.Compared with export trade,import trade requires a lower threshold for the threshold variables to take effect,and imports have a greater and more significant role in promoting green technological progress in Central Asian countries.
