Abstract: The paper put forward the hypothesis that the differences of consumption type are the dominant factors which lead to the difference of happiness. Based on this hypothesis, the paper introduced a new perspective to divide consumption types. At the same time, applied structure equation analytical method empirically examines the conduction mechanism between consumption types and happiness. The results showed that consumption is the main factor which influence happiness index significantly; different consumption types led to different conduction paths. It means that limited improve happiness consumption had no significant effect on current happiness or future happiness; excepted improve happiness consumption only affected expected future happiness index significantly; sustainably improve happiness consumption affected current happiness index significantly and directly. It also affected expected future happiness index by way other factors in directly.
