我国能源效率的动态调节机制在1998年前后发生了平滑转换,机制转换的主要引导因素是国内外能源相对价格大幅波动的冲击,冲击形成的“能源价格陷阱”导致能源效率向上的粘滞性增强、向下的粘滞性减弱,这也是我国能源效率在2003年以后出现下滑趋势的根本原因。在“能源价格陷阱”中,相对价格上涨对能源效率的促进作用减弱,而价格相对下降的负向作用增强,所以,通过能源消费税和节能补贴提高能源效率是更为可行的选择。
The dynamic adjustment mechanism of China’s energy efficiency has undergone a smooth transition since 1998. The main guiding factor for the conversion of the mechanism is the impact of sharp fluctuations in the relative price of energy both at home and abroad. The “energy price trap” formed by the shock leads to the stickiness of energy efficiency Sexual enhancement, down the viscosity weakened, which is the root cause of the decline in energy efficiency in China after 2003. In the “energy price trap”, the relative price increase has weakened the promotion effect of energy efficiency and the negative effect of relative price decline has increased. Therefore, it is more feasible to increase energy efficiency through energy consumption tax and energy subsidy.
