ENERGY INTENSITY CHANGES AND ITS INFLUENCING FACTORS DURING THE INDUSTRIALIZATION IN CHINA

Abstract

Abstract: This paper investigates the energy use of industry sectors in China.We estimate the energy intensity index changes by using Fisher ideal index decomposition model.The analysis leads to the following conclusions.First,the energy efficiency in China has been substantially increased with the reform and open policy;the contribution of energy efficiency share is absolutely dominant;and the cumulative effect of changes of industry structure is basically negligible.Second,the dropping trend of energy intensity slows down,and the influence of technological progress in industrial sectors on improving energy efficiency reduces year after year.Finally,we find that from 1981 to 2007,with an increase of 1% of TFP(total factor productivity) in China,energy consumption intensity correspondingly decreases about 0.33%.As the key and long-term factors influencing energy use,the total factor productivity and its continuous growth has led to the decrease of energy intensity in the rapid development of China's economy.

Key words: energy intensity, Fisher ideal index decomposition model, China, total factor productivity

摘要： 本文利用费雪指数分解模型从产业层面考察了我国能源强度指数的变化及影响因素,研究结果表明:(1)改革开放以来,中国能源效率得到了大幅度提高,在能源消耗强度下降的诸因素中效率份额的贡献占绝对主导,结构份额的影响较少,产业部门结构变动对能源消耗强度的累计影响基本上可以忽略。从时间演变的角度看,能源强度下降幅度呈现明显逐年放缓趋势,产业部门技术进步对能源效率提高的影响逐年减低。(2)1981—2007年,全要素生产率水平(ΔTFP)每提高1%,能源消耗强度(ΔI)相应地降低约0.33%。作为决定能源利用效率的关键因素和长期因素,全要素生产率的不断提高导致了我国经济快速发展下能源强度不断降低现象的发生。
