能源节约型技术进步及其对能源效率的影响研究

With China's rapid economic development, energy shortage and environmental problems are increasingly prominent. So that improving energy efficiency becomes the inevitable choice for China's sustainable development, and the key to increase energy efficiency is technical progress. This paper puts energy into the CES function, and merges labor and capital into non-energy factor, forming a two nested CES function. Based on the relevant data of Chinese industry from 1990 to 2012, we come to a conclusion that the elasticity of substitution between energy and non-energy factor is 0.43, i.e.there exists a complementary relationship between them. Regarding the increasing trend of energy efficiency, we conclude that China's technical progress tends to be an energy-saving one. The regression test results prove that energy-saving technical progress has a significant positive effect on energy efficiency, and raising the price of energy can improve the efficiency to a certain extend.
