Applying the model of Logistic,this paper studied the gender differences of aging support for peasants between sons and daughters based on data gathered from seven hundred and twenty-six peasants from thirteen counties of Sinkiang province.The results showed that gender difference was no longer prevalent from the four aspects including financial support,daily life care,spiritual solace and general impression.Having child or not other than the number of children played a significant part in the aging supports for peasants.In terms of the number of children,it was not the number of daughters but the number of sons that is more influential to raising the old.The System of New Rural Social Pension Insurance,to a certain extent,lowered peasants' dependence on children for aging supports.With regard to the national difference,it mainly manifested between the Han nationality and Uyghur nationality and Kazakh nationality.The minority peasants held a more conservative view on aging supports compared with the Han nationality,which meant sons were the main economic source yet daughters the spiritual source particularly the daily life care.
