国际垂直专业化对中国环境效率的影响研究

Research on Impact of International Vertical Specialization on the Environmental Efficiency in China

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 enviro.mental efficiency when the eastern region is concerned.
