基于CHIPs调研数据可知,农民工收入与其幸福感的关系同样表现出＂Easterlin悖论＂。实证研究结果表明：（1）对农民工幸福感起正向作用的并非家庭收入本身,而是扣除生活必要开支后的剩余部分,说明农民工幸福水平的提升并不止步于基本需求的满足。（2）农民工与城市居民间的收入差距严重损害其幸福感,但随着农民工收入的提高,其损害程度会逐步降低;与同村村民间的收入差距仅负向影响低收入者的幸福感。（3）收入对新老一代农民工幸福感的影响呈现出明显的代际差异,与新生代农民工相比,老一代农民工更关注经济因素的作用,与城市居民、同村村民间的收入差距均不利于老一代农民工幸福水平的提升;但对新生代农民工而言,与同村村民间的收入差距作用并不显著,说明他们并不将同村村民视为相对收入的参照对象。（4）当前,农民工的幸福感并非局限于单一的经济诉求,健康状况、教育水平、婚姻状况、流动方式等非经济因素同样作用明显。

英文摘要：

China＇s peasant workers,as a special group nurtured by urban-rural registration system,reached 274 millions in 2014.Studies on this massive group involve a great variety of aspects except the relationship between peasant workers＇income and their subjective well-being（SWB）.This paper extends previous researches by systematically investigating the impact of income on peasant workers＇SWB based on the China Household Income Project survey（CHIPs）data.Besides,compared with the previous studies,this study contributes to the literature by taking into account the heterogenicity among peasant workers,discussing the different effects ofincome on SWB of peasant workers with different income levels,and further providing answers to why the impact of income on new generations of peasant workers＇SWB differs from that on their old counterparts.The results of ordinal logit model reveal that：（1）The Easterlin paradox has emerged in peasant worker group,and it is not the family income per se but the remainder of family income after deducting necessary living expenses that positively affects peasant workers＇happiness,which indicates that raising peasant workers＇SWB is not confined to the satisfaction of basic physiological needs for the moment.（2）The urban-rural income gaps reduce all peasant workers＇SWB,but the reduction decreases with the rise of peasant workers＇income.However,income gaps among rural residents negatively influence low-income group＇s happiness.（3）The effects of income on peasant workers＇happiness differ in two generation groups,specifically,income affects old generation group＇s happiness more severely than that of new generation group.As far as income gaps are concerned,both the urban-rural and rural-rural income gaps have negative effects on old generation group＇s happiness,but in terms of their new counterparts,the effect of the latter is not statistically significant.This conclusion illustrates that the new generation group does not treat rural residents as its referen
