摘要
近几年,关于技术进步的理论和经验研究开始关注刻画和估计技术进步的偏差,其反映的是技术进步中伴随的生产结构变化。本文使用中国分行业的面板数据,在目前仅有的两种计量方法外,结合中国数据特点,在一个新的框架内估计了中国从1982年到2000年间的技术进步偏差。各种统计检验表明,本文的方法能够合理地被用来估计技术进步偏差。结果显示,1982年到2000年间,从全行业的角度看,生产结构变得更倚重于能源与非能源要素,而劳动要素在生产中的影响相对有所削弱。
Recent development in theoretical and empirical studies about modeling technical change has shifted the attention to the biases of technical change, which reflects the changes in the structure of production with technical progress. This paper uses the panel data that contains 33 industries of China and proposes a new framework to estimate the biases of technical change from 1982 to 2000, which is a complement to the existing two frame- works. The statistical tests in this paper suggest that our framework can deal with the issue well. According to the results of estimation, it can be found that the production on average become more dependent on the energy and non-energy inputs over the sample period; meanwhile, the role of labor input in the production is weakened.
