【摘要】：进入21世纪以来,有关于技术进步偏向性的研究越来越受到经济学界的关注,且在理论和实证上的研究成果均支持了技术进步偏向性存在的事实。这不仅改变了以往学术研究对于中性技术进步的假设条件,使其变得更加符合现实情况,而且也为从学术上解释一些经济现象增加了新的研究视角。然而目前针对技术进步偏向性产生原因的文献研究还较少,已有的文献也多数是以发达国家为视角,为此本文尝试利用理论和实证两种分析方法分析我国进口贸易结构和技术进步偏向性之间的关系,从进口贸易结构的角度对我国技术进步偏向性进行解释。本文的研究发现:(1)我国在1988-2015这个时间段内,劳动和资本要素之间的要素替代弹性为0.894,在这个基础上计算的我国技术进步偏向性总体上偏向资本,且在2004年后技术进步偏向性波动幅度明显变大。(2)协整方程分析表明我国进口贸易结构对技术进步偏向性存在显著的影响,且进口贸易中高新技术产品的比重越大,我国的技术进步偏向性越偏向资本;其次来自俄罗斯的进口贸易额比重越大,对我国技术进步偏向性偏向资本存在抑制作用。(3)控制变量的实证结果表明人力资本以及以人均资本衡量的要素结构对我国技术进步偏向性偏向资本存在正向的作用
[Abstract]:Since the beginning of the 21st century, more and more attention has been paid to the research of technological progress bias, and both theoretical and empirical research results support the fact that technological progress bias exists. This not only changes the hypothesis of neutral technological progress in previous academic studies and makes it more in line with the reality, but also adds a new research perspective to explain some economic phenomena from the academic point of view. However, at present, there are few researches on the causes of technological progress bias, and most of the existing documents are from the perspective of developed countries. Therefore, this paper tries to analyze the relationship between the structure of import trade and the bias of technological progress by using both theoretical and empirical analysis methods, and explain the bias of technological progress in China from the perspective of import trade structure. In the period 1988-2015, the element substitution elasticity between labor and capital is 0.894. On this basis, the bias of technological progress in China is generally biased towards capital. The analysis of cointegration equation shows that the structure of China's import trade has a significant influence on the bias of technological progress, and the higher the proportion of high-tech products in the import trade, the greater the proportion of high-tech products in the import trade. The more biased our technological progress is towards capital, the bigger the proportion of import trade from Russia is. The empirical results show that human capital and the structure of factors measured by capital per capita play a positive role in the existence of biased biased capital of technological progress in China.
