西部省会城市城镇居民可支配收入差异分析——基于“变异系数”的角度

Analysis on the Differences of Disposable Income of Urban Residents in the Western Provincial Capital City:Perspective on Coefficient of Variation

改革开放以来,随着经济的发展,人们的生活质量有了很大的改善,收入水平显著提高,但是收入差距问题日渐显现。城镇有着带动经济发展的作用,城镇居民可支配收入差距拉大往往会成为影响社会和谐和稳定的关键因素。文章借助于变异系数,对西部12个省会城市的城镇居民可支配收入差异及其趋势进行分析。结果显示,从2003—2012年西部省会城市城镇居民可支配收入差异的变异系数从0.115扩大到了0.204,表明西部省会城市城镇居民可支配收入的差异逐年增大。同时认为,区位因素、经济增长水平、教育投入、基础设施建设等是造成差异产生和不断扩大的主要原因。
