摘　　要：提高能源效率是实现经济可持续发展和减少污染排放的根本途径。基于非线性平滑转换模型的分析显示,能源价格对能源效率的影响机制存在非线性的平滑转换。机制转换的主要引导因素是国内外能源价格指数的相对变化,机制转换的阈值近似为1。目前我国能源价格对能源效率的影响比较接近高效机制运行,增强能源价格的灵活性,可以实现能源消费者的自我选择,是提高我国能源效率的可行选择。Improving energy efficiency is the fundamental approach to realize consistent economic development and reduce pollution emission. The analysis based on nonlinear smooth transition model shows that the mechanism of the influence of energy price on energy efficiency exists in nonlinear smooth transition. The main factor influencing mechanism transition is the relative changes in the relative price index home and abroad. The threshold value of mechanism transition approximates to 1. At present, the influence of energy price on energy efficiency at home approaches to highly - efficient mechanism operation. To improve the flexibility of energy price can benefit consumers＇ self - selection, which is an alternative method to improve energy efficiency in China.
