我国能源强度变化的影响因素分析及其实证研究

The Analysis of Energy Intensity Determinants and Empirical Research in China

以1990-2008年能源强度统计数据为样本,利用脉冲响应函数与方差分解模型,对能源强度变化影响因素的动态作用特征及其影响效果进行了研究。实证结果表明:能源强度自身与第二产业比重对能源强度影响程度较大,能源价格变动与技术进步也对能源强度有一定影响,影响因素共同通过内在联结关系与相互作用机制,对提高能源效率有积极作用。

Base on the energy intensity data of period 1990-2008,this paper uses impulse response function and variance decomposition model to analysis the influencing factors and effects of energy intensity.The empirical results show that： the energy intensity of itself and the proportion of secondary industry have a larger impact on energy intensity;the change of energy price and technological progress also play a certain impact on energy intensity;the link with the internal relations and interaction mechanisms can play an active role in improving energy efficiency.
