中国农村内部区域之间收入差距分析——基于泰尔指数的测度

本文运用泰尔指数及其分解方法，分析了我国农村内部东中西部三大经济地带之间收入差距的变化趋势和成因。文章认为，上世纪90年代以来，我国农村内部的收入差距呈现出先缩小后扩大的趋势。收入差距主要来源于区域内部。不同收入来源中，工资性收入的不平等性最强，其组间贡献波动幅度也最大；家庭经营收入的分布最为平均，组间贡献也最小；虽然财产性收入和转移性收入所占比例较小，但是他们自身的收入差距在不断扩大。文章建议，加快农业产业结构调整，提供更多的非农产业就业机会，保证农民从结构调整中增收。在稳定现有土地制度的基础上，应该给予落后地区更多的关注和支持，兼顾农民增收和公平分配。
