摘要: 区位基尼系数虽然广泛用于度量产业的空间集聚,但很少有文献分析其应用的局限性和使用不同基准分布的影响。本文首先系统分析了区位基尼系数的三个主要缺陷:(1)受企业规模影响;(2)受地理单元设定的影响;(3)受产业分类影响。之后,本文分析了使用不同基准分布计算区位基尼系数所存在的经济意义上的差异,以及因此可能产生的理解偏差;同时,讨论了几种国内研究尚未使用过的比较有意义的基准分布形式。最后,本文以中国2004年制造业数据为例,解释了上述提出的问题。

Abstract: Locational Gini index has been widely used to measure industrial spatial agglomeration, but few research analyses its limitation and the impact of using different benchmark distributions. The paper first systematically analyses three main drawbacks of locational Gini index: (ⅰ) affected by firm scale; (ⅱ) affected by the specification of areal units; (ⅲ) affected by industrial classification. Then, the paper analyses the economic difference between locational Gini indices calculated using different benchmark distributions and the resulting understanding biases. Meanwhile, the paper investigates several other meaningful benchmark distributions which haven’t been used in domestic research. Finally, the paper takes Chinese manufacturing data in 2004 for example to interpret the problems mentioned above.
