能源效率影响经济增长的机理及其效应研究

本文研究了能源效率对中国经济增长的影响及其传导机制。文章采用投入导向的规模报酬不变的Malmquist-DEA生产率指数对中国能源效率进行测算，在此基础上，基于1993—2011年中国29省(市、区)的面板数据，实证检验了能源效率对中国经济增长的影响。研究结果表明，提高能源效率有利于促进中国经济增长，且进一步的分析发现，能源效率通过提高人力资本积累、对外贸易和创新水平间接促进了中国经济增长。这表明能源效率影响经济增长的作用机理在于人力资本积累、对外贸易和创新三个方面，其中创新是能源效率影响经济增长的最重要传导渠道。  

On the Mechanism and Effect of Energy Efficiency's Influence on Economic Growth

This paper analyzes the energy efficiency's influence on China economic growth and its transmission mechanism. China energy efficiency was calculated by Malmquist-DEA productivity index of input-oriented constant returns to scale. Furthermore, panel data of China's 29 provinces(including cities and districts) from 1993 to 2011 was collected, and the empirical result shows that energy efficiency influences China economic growth. The whole research demonstrates that improving energy efficiency will promote China economic growth. Further analysis reveals that energy efficiency indirectly boosts China economic growth by raising the level of human capital accumulation, foreign trade and innovation. Therefore, action mechanism, which energy efficiency influences economic growth, are from three dimensions, namely, the accumulation of human capital, foreign trade and innovation, among which innovation is the most important transmission channel.
