区位基尼系数的计算、性质及其应用

基于产业规模探索区位基尼系数的简化计算、区域分解和两位数产业分解,给出产业份额、区位商以及产业份额空间测度加权区位基尼系数的分解公式，提供相对边际效应和增量分解的计算公式。利用我国2004年、2008年的经济普查数据，计算国民经济19个字母产业的区位基尼系数，得出以产业份额计算的区位基尼系数更能反映产业聚集程度的结论,并使用产业份额区位基尼系数进行实证分析。

Calculations and Characters of the Locational Gini Index and Its Application

Industry share and location quotient are functions of industrial scale, this paper discusses simplifying calculation, regional and double-digit industry decomposition of locational Gini index based on industrial scale.Some formulas are given how to decompose locational Gini index of industrial share, location quotient and weighted industrial share; then some methods are given to analyze relative marginal effects and decompose increment of location Gini index.Using the data of Chinese economic survey yearbook in 2004 and 2008, location Gini index of 19 letter industries are computed, and it is cognized that location Gini index of industry share has better performance than two others.Also, an empirical analysis is carried out by location Gini index of industry share.
