国际垂直专业化对中国环境效率的影响研究

摘要

本文通过垂直专业化系数评价了我国工业行业垂直专业化程度，继而借助工业行业垂直专业化程度与环境效率散点图，分析得出我国更倾向于以清洁工序生产嵌入全球生产网络。通过国际垂直专业化分工、控制变量与环境效率面板数据模型的回归分析得出，从我国整体来看，垂直专业化分工对环境效率影响不显著，但对东部地区而言，垂直专业化可加速环境效率的提升。%The paper first evaluates the degree of vertical specialization in China through vertical specialization index and with a scatter chart analysis it finds clean production as a more likely way for China to engage in global production network . The paper constructs a panel model deriving from the data of vertical specialization , control variables and environmental effi-ciency, and through a panel data regression analysis it concludes that the coefficient is not significant for the country as a whole, but vertical specialization can promote the environmental efficiency when the eastern region is concerned .
