【摘要】：本文基于多要素的CES生产函数,构建了中性技术进步、偏向型技术进步对全要素生产率增长的影响框架,将全要素生产率增长率分解为中性技术进步效率变化效应、非公共资本增强型技术进步效率变化效应、劳动-非公共资本之间的偏向型技术进步效应、公共资本-非公共资本之间的偏向型技术进步效应。在此基础上,利用1990-2014年数据进行实证研究发现,中国要素替代弹性显著大于0且小于1;劳动的生产效率是提高的,而公共资本与非公共资本的生产效率是下降的;技术进步偏向资本,并且偏向非公共资本的程度大于公共资本,这是导致中国全要素生产率增长减缓的主要原因。进一步实证分析表明,2008年金融危机后,政府加速公共资本的投放导致技术进步越渐朝向公共资本方向发展,进一步抑制了全要素生产率增长。因此,为实现生产率提升和经济增长方式转变,应充分发挥自身劳动力的比较优势,适度减少公共资本,尽快转向依赖技术进步、技术效率变化和非公共资本的轨道上来。
[Abstract]:Based on the CES production function of multiple factors, this paper constructs the framework of neutral technological progress and biased technological progress on the growth of total factor productivity, and decomposes the growth rate of total factor productivity into the efficiency change effect of neutral technological progress. Non-public capital enhanced technological progress efficiency effect, labor-non-public capital bias technology progress effect, public capital-non-public capital bias technology progress effect. On this basis, the empirical study based on the data from 1990 to 2014 shows that the elasticity of factor substitution in China is significantly greater than 0 and less than 1, and the productivity of labor is improved, while the productivity of public capital and non-public capital is decreased. Technological progress is biased towards capital and non-public capital to a greater extent than public capital, which is the main reason for the slowdown of China's total factor productivity (TFP) growth. Further empirical analysis shows that after the financial crisis in 2008, the government accelerates the investment of public capital, which leads to the development of technological progress towards the direction of public capital and further restrains the growth of total factor productivity (TFP). Therefore, in order to improve productivity and change the mode of economic growth, we should give full play to the comparative advantage of our own labor force, reduce public capital moderately, and turn to the track of relying on technological progress, technological efficiency change and non-public capital as soon as possible.
