技术进步方向是影响要素收入份额的重要原因,但技术进步方向的影响因素却被忽略了。本文利用1980-2011年中国制造业分行业面板数据,采用标准化供给面系统方法测度了技术进步方向,并考察了技术进步方向的动态演进过程。研究发现:大多数制造业行业技术进步方向都是偏向资本的,1996年是中国制造业技术进步方向的转折点。在此基础上,分析了1996-2011年技术进步偏向资本的原因,并重点考察了国际贸易的作用。结果表明:国际贸易是中国技术进步偏向资本的主要因素,这是因为国际贸易使中国复制了发达国家的技术进步方向。致使中国技术进步方向有偏的影响因素还包括资本深化、国有经济比重降低、研发投入和外商直接投资的增加。
Biased technological progress is an important factor in affecting factor income shares,but the factors influencing the direction of technological progress are ignored. Based on the normalized supply- side system method, this paper measures the direction of technological progress and the dynamic evolution process in China 's manufacturing industry during 1980-2011. The results show that technological progress of most manufacturing industries is capital-biased; 1996 is the turning point of China's manufacturing technological progress direction. On this basis,we analyze the reasons of biased technological progress during 1996- 2011,focusing on the role of international trade. It is found that international trade has considerable explanatory power for it,because international trade makes our country imitate the direction of technological progress in the developed countries. Such biased technological progress can also be explained by capital deepening,the proportion of state- owned economy,RD investment and foreign direct investment.
