Abstract: Firstly, the paper evaluates vertical specialization degree of our country through vertical specialization index and then draws the conclusion that Chinese tend to engage in clean production through scatter chart analysis. Final the paper constructs panel model deriving from the data of vertical specialization, control variables and environmental efficiency and through panel data regression analysis we can gain some conclusions: from the whole country the coefficient is not significant, but as the eastern region is concerned, vertical specialization can promote the environmental efficiency.

摘要： 本文首先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。再者通过垂直专业化分工、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，但对于东部地区而言，垂直专业化可加速环境效率的提升。
