我国能源强度变化的影响因素分析及其实证研究

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，能够对提高能源效率起到积极作用。

The Analysis of Energy Intensity Determinants and Empirical Research in China

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 .
