Inter-provincial comparison of rural residents' income structure and its evolution: Based on shift-share method
基于偏离—份额法的我国农民收入结构演进的省际比较

An inter-provincial comparison of rural residents' income structure and its evolution trend from 1997 to 2009 is made by using traditional static shift-share and dynamic shift-share analysis method.Results showed that the structure of income sources of rural residents has changed dramatically along with their income growth.The proportion of household business income is declining,and salary income has gradually become the primary source of income in most of the provinces.Static shift-share analysis result showed that structural shift advantage of the rural residents' income in eastern provinces is more obvious than in the western provinces,and the salary income structural shift advantage contributes a lot to the overall income growth;while in western provinces,the differential shift advantage tends to be more obvious and the salary income growth rate in these provinces is higher.According to the structural and differential shift differences,all provinces are categorized into four types: rapid growth type,structural shift-driven type,differential shift-driven type and lagged growth type.Dynamic shift-share analysis result showed that the growth rate of rural residents' income in the eastern coastal provinces has slowed down gradually,and its differential shift disadvantage has become more and more obvious.Yet,the differential shift advantage is intensified gradually in some central and western provinces,but the structural shift advantage in these provinces is not clear,as its contribution to the growth is not big.Therefore,making great efforts to improve the level of rural residents' income,especially the level of salary income,will be of great significance in decreasing regional disparity of rural residents' income growth.
