能源节约偏向型技术进步对经济增长的影响研究

The impact of energy-saving biased-oriented technological progress on economic growth

本文通过构建多要素的CES生产函数和包含偏向型技术进步的超越函数模型,实证考察中国能源节约偏向型技术进步对经济增长的影响,及企业不同来源技术进步要素偏向性及其经济增长效应。研究发现:1991-2015年中国技术进步整体上偏向资本和能源要素,偏向资本和能源使用、劳动节约型;要素替代弹性σ<1,能源增强型技术进步表现为能源节约偏向型;能源节约偏向型技术进步主要通过能源增强型技术进步指数效应促进全要素生产率提高;企业不同来源技术进步的要素偏向性及其经济增长效应存在明显差异,自主创新R&D的经济增长效应最高,技术改进的经济增长效应为负;不同来源技术进步的有偏技术进步经济增长效应明显大于中性技术进步经济增长效应。

In this paper,by constructing multi-factor CES production function and transcendental function model including biased technological progress to empirically analyze the impact of China’s energy-saving biased-oriented technological progress on economic growth,and investigate different source technology progress factor bias and its economic growth effect.The study finds that:from 1991 to 2015,China’s technological progress is generally biased toward capital and energy,bias towards capital-using,energy-using and labor saving.Element substitution elasticity is less than 1,energy-enhanced technology advances are manifested as energy-saving biased-type technological progress.The energy-saving biased-type technological progress promotes the improvement of total factor productivity through energy-enhanced technology progress index effect.The bias of technological advance from different sources and its economic growth effect are obviously different,the economic growth effect of independent innovation R&D is the highest,the economic growth effect of technological improvement is negative.The effect of biased technical progress on economic growth from different sources of technological progress is significantly greater than the effect of neutral technological progress on economic growth.
