摘　　要：本文将出口学习效应拓展到绿色生产率领域,研究出口学习对绿色生产率的非线性影响。利用中国工业企业的微观数据,采用面板分位数模型和面板门限模型,研究出口对企业绿色生产率的非线性效应以及门槛特征。研究发现:出口对企业绿色生产率的影响为正,但该影响在不同分位点有显著性差异,具有非线性特征;同时,出口学习影响企业绿色生产率的非线性效应具有门槛特征,随着企业融资约束门槛值的降低,出口对绿色生产率效应基本呈现先增后减的库兹涅茨倒"U"型结构。本文的结果表明,企业出口可以提升企业的绿色生产率水平,出口学习效应存在;企业出口对其绿色生产率的影响是非线性的,具有门槛效应。This paper extends the theory of learning-by-exporting effect to the field of green productivity,and studies the nonlinear effects of learning-by-exporting on enterprises＇ green productivity. This paper explores the threshold effect of learning-by-exporting on green productivity through panel quantile regression and panel threshold regression model by using the data of China＇s manufacturing enterprises. The results show that the effects of learning-by-exporting on green productivity are positive,and there are three thresholds effects of learning-by-exporting on green productivity. Learning-by-Exporting effect on green productivity show a typical Kuznets inverted ＂ U-shaped curve which increases first and decreases then during both benchmark and robustness tests. This reflects the enterprises can improve their green productivity in a nonlinear mode through the learning-by-exporting effect.
