我国能源效率与经济增长关系研究基于 PSTR 模型的实证∗

摘要

This paper,which uses super efficiency DEA method to calculate the energy efficiency,em-pirically researches the relationship between energy efficiency and economic growth during 2000-2013 by using the panel smooth transition regression model.The empirical results show that there is mechanism conversion effect between economic growth and energy efficiency.When the economic development is in the low income levels,the relationship between energy efficiency and economic growth is linear.While the economic development is in the higher income levels,the relationship between energy efficiency and eco-nomic growth turns nonlinear.And the relationship will smooth the conversion among different mecha-nisms which is bounded by the threshold of per capita GDP.%实证结果表明，能源效率与经济增长之间存在机制转换效应，在经济发展处于低收入水平时，能源效率与经济增长表现为线性关系；在经济发展处于中等或较高收入水平时，能源效率与经济增长之间则表现为非线性关系，并以人均 GDP 的阈值为界，在不同机制之间进行平滑转换。
