能源是社会经济发展最基本的驱动力,是人类赖以生存的基础。随着经济的快速发展,能源约束现象逐渐突出,能源效率偏低是目前的突出问题。论文应用Laspeyres因素分解法,对粤湘黔三省的能源使用强度进行分解分析。研究发现:①三省的能源使用强度差异较大,尤其是广东与贵州能源使用强度相差很大,从发展趋势看,三省的能源使用强度差异会逐渐变小。②三个省份的第一产业结构份额和效率份额都有利于减小能源使用强度,第二产业结构份额均有助于增加能源使用强度,第二产业效率份额都有利于降低能源使用强度,第二产业效率份额在三次产业中作用最大。广东省的第三产业结构份额为负值,而湖南、贵州结构份额多为正值;第三产业效率份额广东、湖南分时段出现正负值,原因有待于探索。贵州第三产业效率份额为负值。③三省的结构份额对能源使用强度都产生负作用;三省的效率份额都有利于降低能源使用强度,具体作用因地区而异。据此论文认为在近期要完成单位GDP能耗降低20%,减少国家能源消耗总量,保证能源安全,经济欠发达或能源使用强度高的地区应是重点整治对象。
Energy is the most basic driving force for social and economic development and the foundation upon which mankind depends. With the rapid economic development, the phenomenon of energy constraints has become increasingly prominent. The low energy efficiency is a prominent issue at present. The dissertation uses Laspeyres factorization method to analyze the intensity of energy use in three provinces of Guangdong, Hunan and Guizhou provinces. The findings are as follows: (1) The intensity of energy use in the three provinces varies greatly, especially the intensity of energy use between Guangdong and Guizhou varies greatly. From the development trend, the energy intensity difference among the three provinces will gradually become smaller. ② The share of the first industrial structure and the share of efficiency in the three provinces are conducive to reducing the intensity of energy use. The share of the secondary industry structure contributes to the increase of energy intensity. The share of the secondary industry efficiency is conducive to reducing energy intensity. The share of secondary industry efficiency in the three industries play the largest role. The share of tertiary industry in Guangdong is negative, while that in Hunan and Guizhou is mostly positive. The share of tertiary industry in Guangdong and Hunan shows positive and negative values for a period of time, which is yet to be explored. Guizhou tertiary industry efficiency share is negative. ③ The share of the three provinces has a negative effect on the intensity of energy use. The share of the three provinces’ energy efficiency is conducive to reducing the intensity of energy use. The specific role varies from region to region. Therefore, the thesis thinks that in the near future, it is necessary to finish the reduction of energy consumption per unit of GDP by 20%, reduce the total amount of energy consumption in the country, ensure energy security, economy is underdeveloped or energy intensity is high.
