摘要
笔者从产业集聚来源出发分析产业集聚对能源效率的作用机制,通过对中介变量——产业竞争力的分析,建立产业集聚与能源效率之间的理论模型。笔者以2000年~2010中国省域制造业20个行业为研究对象,区分专业化与多样化产业集聚,运用系统GMM方法分别探究其与能源效率的作用机制。实证研究表明:制造业专业化产业集聚相对多样化产业集聚更有利于能源效率的提升,过度产业竞争下专业化产业集聚不利于能源效率的提升。
The paper embarks from the sources of industrial agglomeration to analyze the mechanism between industrial agglomeration and energy efficiency,and establishes a theoretical model between industrial agglomeration and energy efficiency through the analysis of the intervening variable-industry competitiveness. The paper uses 20 provincial manufacturing industries in China from 2000-2010 as research objects to differentiate professional and diversified industrial concentration,and it also uses GMM method to explore the mechanism of energy efficiency. Results indicate that the specialized manufacturing industry agglomeration is more advantageous to promote energy efficiency than diversified industrial agglomeration,and specialized industrial agglomeration is unfavorable to improve energy efficiency.
