摘　　要：在社会经济体系研究中,从系统结构和仿真的技术人手,在综合利用SPSS等软件的基础上,通过矩阵运算,测算出行业收入差距基尼系数和泰尔指数,发现行业收入差距不断扩大。根据经济学和系统工程理论筛选影响行业收入差距的因素,构建ISM模型,对行业收入差距成因系统进行测试,通过T检验优化模型和ISM层次筛选法得出主要原因。综合分析得出结论,微观因素行业收入差距产生和扩大的主要原因,经济体制市场化改革是差距产生和扩大的重要环境因素。From the points of systems engineering and simulation, the paper measured both the Gini index and Theil index of income gap by using SPSS and matrix computation, and sifted out important causes on the gap also in economics and systems engineering theories. The research figures out the gap and finds that the disparity is more and more wider. Then the ISM model was built and estimated by T -test. Comprehensive analysis shows that the macro factors are the most important institutional environments, and the micro factors are central reasons of income gap between trades.
