中国工业行业能源强度影响因素的实证分析

An Empirical Analysis of Influential Factor in China's Industrial Sector Energy Intensity

利用中国31个工业行业1998—2004年面板数据,采用分层聚类方法,按年平均能源强度将31个工业行业分为高能源强度行业和低能源强度行业,并对全工业行业、高能源强度行业和低能源强度行业能源强度的影响因素进行了实证分析。研究结果表明,能源价格上涨对提高工业行业的能源利用效率有显著的促进作用;FDI进入程度的增大提高了工业行业尤其是高能源强度行业的能源强度;进、出口商品结构变化对工业行业能源强度没有显著影响;工业内部的行业结构变化对全工业行业和低能源强度行业的能源强度有显著负的影响,对高能源强度行业没有显著影响;R&D投资强度的增加提高了工业行业特别是高能源强度行业的能源强度。

Based on the panel data on China s 31 industrial sectors during the period from 1998 to 2004,this paper firstly utilizes hierarchical clustering method to divide the China s 31 industrial sectors into high energy intensity industries sectors and low sectors on the basis of average annual energy intensity,and then empirically considers the factors that impact industrial energy consumption intensity from the China s 31 industrial sectors and high energy-consuming sectors and low energy-consuming sectors.
