通过分解基尼系数和泰尔指数，研究了1993-2003年吉林省区域不平等的变化，发现第二产业贡献最大，县级市间不平等大于地级市间，且向心力效应解释了基尼系数的变化。
Awakening to the necessity of calculating regional inequality in Jilin Province,first of all,the authors studied the denotative and connotative meanings of regional inequality,and a hypothesis about the regional inequality formation mechanism was propounded;In empirical research,we studied the change of regional inequality in Jilin Province by decomposing GiNi index and Theil index from 1993 to 2003.At last,some conclusions were reached and causes that produced above-mentioned effect were analyzed,too.Firstly,GiNi index and Theil index had relation to economic cycle;Secondly,second industry played the biggest part in regional inequality.Thridly,Theil index were bigger between county-level cities than prefecture-level cities;Fourthly,from 1993 to 2003 Theil index between county-level cities increased gradually,but it worked the other way around for prefecture-level cities;Fifthly,the centripetal effects explained successfully the change of GiNi index from 1993 to 2003,so we can draw a conclusion that it is not right to think regional inequality were in direct contact with proportion of the three industries;At last some pieces of advice are given on the basis of the above conclusions.
