甘肃省民族地区与非民族地区县域经济差距研究——基于基尼系数分解的视角

An Analytical Study on the County Economy Gap between Ethnic Minority Areas and other Areas Based on the Gini Coefficient Decomposition Method——Taking Gansu province as an example

该文将甘肃省69个县(市)划分为民族县和非民族县两大群组,以两大群组为基础,运用基尼系数分解方法测度了1994—2014年甘肃省县域经济差距的构成和变化。结果显示,甘肃省县域经济差距显著,民族县内部、非民族县内部和非民族县群间经济差距均在逐渐扩大,民族县群间经济差距在逐渐缩小。在导致甘肃省县域经济差距变化的各种效应中,人均GDP增长效应、民族县群间差距效应和交互效应均起到了缩小甘肃省县域经济差距的作用,群内差距效应和非民族县群间差距效应则相反。因此,为缩小甘肃省县域经济差距,应大力提高贫困县经济水平,着力缩小民族县内部经济差距。

This paper divided 69 counties （cities） in Gansu province into ethnic county group and other county group, applying the Gini coefficient decomposition method to measure the county economic gap formation and change in Gansu province from 1994 to 2014. It concludes that the county economy gap is significant in Gansu province, Inside the national county and other county and between other county economic gap are in gradually expanding, economic gap between ethnic county group is narrowing. All of the various effects that causing economic gap, the GDP per capita growth effect and the ethnic county economic effect and the interaction effect all have played an important role in narrow the economic gap, on the contrary, inside group effect and between ethnic county group effect expand the county economic gap. Therefore, it should improve the level of county economy, strive to narrow the economic gap within ethnic county.
