中国加工贸易增值率影响因素的实证研究——基于2001年～2010年省际面板数据的分析

An Empirical Analysis on the Influencing Factors of Processing Trade Value-added Rate in China——Based on Chinese Provincial Panel Data from 2001 to 2010

增值率不高是中国加工贸易发展中存在的重要问题.笔者用2001年-2010年省际面板数据,运用动态面板系统GMM方法对中国加工贸易增值率影响因素进行实证研究,结果表明：研发能力、产业结构是影响中国加工贸易增值率的重要因素,提高研发能力可以提高加工贸易增值率,第二产业所占的比重越高,加工贸易增值率越高;资本深化程度、技术水平、人力资本、劳动力成本对中国加工贸易增值率影响不显著;外商直接投资对全国加工贸易增值率影响不显著,对东部地区加工贸易增值率有显著负效应.

Low value-added rate of processing trade is an important problem of the development of processing trade in our country. In this paper, the author empirically analyzes factors that affect the value-added rate of China＇s processing trade by using the system GMM method of dynamic panel data and the panel data of Chinese provinces from 2001 to 2010. The results show that the ability of research and development and the industrial structure have an important effect on the value-added rate of Chinese processing trade. Capital deepening, technological level, investment, human capital and the average wage of manufacturing labor have no significant effect on the value-added rate of processing trade. Foreign direct investment rate has an insignificant effect in China and has a significant negative effect on processing trade value-added in the eastern region.
