我国农民收入时空差异的地域与因子结构双重解析

根据泰尔系数和基尼系数可按地域和收入来源进行分解的特性,对我国1997—2009年间各省份农民收入时空差异进行地域和因子结构双重解析。结果表明,省际间农民收入呈小幅波动增大态势;三大地带内差异是构成农民收入差异的主导部分,尤其是中部地带内省际间差异和贡献居首要地位;因子结构分解则显示工资性收入对总体非均衡程度的贡献最高。着力加快中、西部地区的工业化、城镇化进程,推进农业剩余劳动力向城镇转移或向非农产业转移,提升其工资性收入水平,并从政策、财政和科技等方面支持落后地区加快发展家庭经营是缓解农村地区省际收入差距并促进农村经济区域协调发展的有效途径。

Regional and Factorial Analysis of Spatio-temporal Inequality of Rural Residents' Income in China

According to the characteristics of Theil coefficient and Geordie coefficient decomposition based on area or source factor components,rural residents’ income spatio-temporal inequality from 1997 to 2009 has been double analyzed.Results show that the overall rural regional income disparity has been enlarged discontinuously from 1997 to 2009;and the regional decomposition shows that the disparity of intra-East,intra-Middle and intra-West contribute the major proportion to the overall inequality,especially the intra-Middle zone.While factor decomposition analysis indicates that disparity of wage income contribute the major proportion to the overall inequality,that’s to say wage income plays an important role in China’s rural regional income inequality.Thus,to promote industrialization and urbanization in Middle and West underdeveloped areas,to encourage farmers to gain more wages through outgoing employment,to support backward area to speed up the development of family business are effective ways to alleviate rural income inter-provincial inequality and to promote regional coordinated development of rural economy.
