收入不确定性对城乡居民消费支出影响的比较研究——基于中国省级面板数据的分析

Comparative Research of Income Uncertainty on Households' Consumption:On China's Provincial Panel Data

基于2000—2009年的面板数据,在测度中国城乡居民收入不确定性的基础上,比较研究了城乡居民不同类别收入的不确定性对居民分类消费支出的影响,结果表明:各省城乡居民各类收入均出现了不确定性;不同省份城乡居民各类收入的不确定性有所差异,各省内部城乡居民收入的不确定性也不相同;从全国的视角看,各类收入的不确定性对总体消费造成了结构性影响,农村居民收入的不确定性大于城镇居民收入的不确定性。

Based on the panel data of 2000-2009,this paper measures income uncertainties of urban and rural households to compare influences of different income uncertainties on different consumption expenditure between urban and rural households.The result indicates：urban and rural households have income uncertainty;different provinces have different income uncertainties,and income uncertainties between urban and rural households are also different;from the national angle of view,income uncertainties have structural influence on the overall expense,income uncertainties in rural areas are larger than in urban areas.
