工业化过程伴随着巨大的能源消耗。本文将能源、资本和劳动力视为重要的生产要素投入,利用技术可变的面板随机前沿生产模型,估算了1995~2004年我国省级的全要素生产增长率(TFPG)。进一步将TFPG分解为技术进步、技术效率和规模效率增长。结论显示:(1)样本期内能源的产出弹性显著为正,且从2002年起其产出弹性大于劳动力产出弹性。(2)我国东中西部三个地区TFPG依次递减。(3)技术进步增长是TFPG主要推动力,其次是规模效率,而技术效率对TFPG起到负的影响,且增长逐年递减。
The industrialization process is accompanied by huge energy consumption. In this paper, energy, capital and labor are regarded as important input of production factors, and the total factor production growth rate (TFPG) at provincial level of China from 1995 to 2004 is estimated by using the stochastic frontier production model with variable technology. TFPG further broken down into technological advances, technical efficiency and economies of scale. The conclusions are as follows: (1) The output elasticity of energy is significantly positive during the sample period, and its output elasticity is greater than that of the labor force since 2002. (2) The TFPG of three regions in the eastern, central and western parts of China decreased in turn. (3) The growth of technological progress is the main driving force of TFPG, followed by the scale efficiency, while the technical efficiency has a negative impact on TFPG, and the growth decreases year by year.
