中文摘要：

以贸易理论为基础，以31个中国工业行业2003—2010年数据，建立面板计量模型验证该影响机制，并将TFP效应进行分解，分析了参与垂直专业化中行业差异造成不同影响效应的原因。实证检验结果表明：参与垂直专业化有利于工业行业总体TFP的提高，但资本密集度高、出口外向度高和市场集中度低的行业参与垂直专业化更有利于行业TFP的提升；行业差异的不同影响效应是通过对技术效率效应（EF）和技术进步效应（TE）的不同效果而影响TFP变化结果的。

英文摘要：

In this paper, I empirically make an analysis on the related data of China＇s 31 indus- tries from 2003 to 2010 to testify the functioning mechanism of vertical specialization on the total factor productivity （TFP） based on the trade theory. Furthermore, I also make explanation about the reason for the different effect of different industry, and TFP is dispersed into two effects. In this paper, it concludes that the industries in the vertical specialization with high capital and export intensity can improve the TFP while the industries with high market-concentration can not. And different effects of industry differences will has an impact on changes of TFP through the different effects of technical efficiency （EF） and technical progress （TE）.
