我国能源强度区域差异影响因素的实证研究——以陕西和广东为例

AN EMPIRICAL RESEARCH ON INFLUENCING FACTORS OF CHINESE REGIONAL DIFFERENCE OF ENERGY INTENSITY——Based on Shaanxi and Guangdong Province

本文通过完全因素分解法,对陕西省和广东省1997-2006年能源强度差异的影响因素进行了实证研究。研究结果表明陕西各产业能源强度过高是陕西能源强度高于广东的主要因素,而工业结构中高耗能产业比重较大是其次要因素。因此,陕西要达到国家提出的五年内单位GDP能耗降低20%的战略目标,一方面需要运用价格、税收和财政补贴等综合的调控手段推动节能技术的开发和利用,建立合理的能源价格体系以有效的降低各产业部门的能源强度,另一方面应根据陕西的要素禀赋进行适当的产业结构调整。

Energy intensity is a measure of the energy efficiency of the regional economy. Energy intensity of western regions is higher than that of east regions. For example, energy intensity of Guangdong province is 0.77t Standard coal/104 yuan, but that of Shaanxi province is 1.43t Standard coal/104 yuan in 2006. The excessively high energy intensity in western regions has the negative effect on the economic growth. Chinese government has recently set a target of reducing energy consumption intensity by 20% during the Eleventh Five-Year-Plan period （2006-2010）. Thus, it is significant to research into the regional difference of energy intensity of China. There are two factors which affect regional energy intensity： regional industrial structure and regional sector energy efficiency. Based on complete decomposition mode, this paper divides the difference of regional energy intensity into regional industrial structure share and regional sector energy efficiency share between Shaanxi and Guangdong province from 1997 to 2006. The results indicate that regional sector energy efficiency is the major factor of regional difference of energy intensity between Shaanxi and Guangdong province. Therefore, in order to achieve the goal, a series of measures should be taken to reduce the energy intensity of Shaanxi province. Firstly, research into energy conservation technology should be promoted, and the reasonable energy price system should be established. Secondly, the industrial structure of Shaanxi province should be adjusted reasonably.
