能源化工产业集聚水平实证研究--基于E-G指数的视角

摘要

Using E-G index, this paper measures the agglomeration degree of E&C industry in China from 2005 to 2012 in dimensions of time, regional space and industrious structure. The findinds are as follows:within the industry, the upstream has a higher degree og agglomeration, while the phenomenon of agglomeration is not conspicupus in the middle and downstream of the industry;viewed in time, the agglomeration degree in the E-C industry rises slowly; and spatially speaking, the up-stream of the E-C industry in western areas has a higher degree of agglomeration than in eastern, central and northweatern are-as where the phenomena of agglomeration do not have certain regular pattern.%本文采用E-G指数，从产业空间、时间和地理空间等维度测度中国2005-2012年能源化工产业集聚状况。在产业内部，上游行业集聚水平非常高，中游和下游行业集聚现象不明显；在时间上，能源化工产业集聚水平在全国范围内呈缓慢上升趋势；在空间分布上，西部地区上游行业集聚程度非常高，部分行业在东部、中部和东北呈现集聚现象，但并没有显现一定的规律。
