我国能源效率对产业结构演变响应的区域差异研究

RESEARCH ON REGIONAL DIFFERENCES OF MECHANISM OF ENERGY EFFICIENCY RESPONSE TO INDUSTRIAL RESTRUCTURING IN CHINA

通过分析我国30省(市、自治区)产业结构和能源效率演变特征,建立向量自回归模型,揭示能源效率对产业结构演变的响应机理及区域差异。结果显示:东部地区产业结构演变高度大于中西部和东北地区,我国能源效率总体呈自东南向西北递减态势,同时,两者在地区内部均存在较大差异;北京、上海第二产业对能源效率提高的抑制效应已经显著显现,天津、辽宁和黑龙江初步显现,其他省份尚未显现;东部、中部与东北、西部地区产业结构演变对能源效率提高总体分别呈正向推动、负向抑制和前期正向推动后期负向抑制效应。

With the economic development of the society in China, the energy problem has already become an important restricting factor, how to improve the energy efficiency are becoming the current hot spots in society from all walks of life. Evolution of the industrial structure is one of the important factors to affect energy efficiency, foreign and domestic scholars have given sustained attention to the relation between China＇ s industrial structure and energy efficiency. Because of the difference of the analytic methods, the study periods, the study scopes and the evaluating indicators cause even the oppsite view in existing studies. The authors, by analyzing the characteristics of energy efficiency and industrial structure of 30 provinces in the mainland of China, establishing a VAR model and using the impulse responses function （IRF）, reveals the mechanism of energy efficiency response to industrial structure evolvement and the regional differences. Some conclusions can be drawn as follows： ① the level of the industrial structure evolvement in Eastern Region is higher than that in Central Region, Western Region and Northeastern Region; ② the energy efficiency in southeast to the northwest is overall decreased in China from 1985 to 2010, energy efficiency are significantly different between provinces; ③ the inhibition of secondary industry on the energy efficiency improvement in Beijing and Shanghai has been significantly evolved, preliminary in Tianjin Liaoning and Heilongjiang, not yet appeared in other provinces; ④the response of the energy efficiency improvement to the industrial structure evolvement has a positive promotion in Eastern Region, a negative inhibition in Central Region and Northeastern Region, however, in Western Region, it has a positive promotion in the former and a negative inhibition in the later. It shows three different dynamic response processes from Eastern to Northeastern and Central to Western region, its main driving mechanism lies in the different phase characteristics of the various regional economic and social developments.
