产业空间集聚水平测度的模型运用与比较

Application and Comparison of Measurement Model of Industrial Spatial Agglomeration Level

文章选取区位熵、行业集中度、赫芬达尔指数、空间基尼系数、EG指数这五种具有代表性的产业集聚测度方法,以包装产业为研究样本分别进行了测度。结果表明,五种统计模型对各省市产业空间集聚测度水平表现出了一定程度的差异性,且根据地理单元划分,均表现出东部地区产业空间集聚程度高、中部地区产业空间集聚程度一般,而西部、东北部地区产业空间集聚程度分散。根据五种测度方法的排序结果,从离散程度、相似度以及综合测度对测度方法的相对有效性进行比较分析,发现EG指数最为有效,行业集中度次之,空间基尼系数相对有效性最差。

This paper selects five representative industrial agglomeration measurement methods such as location quotient, industry concentration, Herfindahl index, spatial Gini coefficient and EG index to measure the research samples of packaging industry respectively. The results show that the five kinds of statistical models present a certain degree of difference at the measurement level of industrial spatial agglomeration in various provinces and cities; according to the geographical unit, the eastern region has a high degree of industrial spatial agglomeration, while the industrial spatial agglomeration degree of the western and northeastern regions is scattered. The paper uses the ranking results of five measurement methods to compare the relative validity of measurement methods from the perspective of discrete degree, similarity degree and comprehensive measurement, and finds that EG index is the most effective, industry concentration degree method the second, and the spatial Gini coefficient method the worst.
