Abstract:Based on the data of the China health and retirement longitudinal study (CHARLS),this paper reveals the urbanrural difference of social support,and its impact on health situation,and life satisfaction for the aged via Chisquare test.Based on binomial Logistic analysis of regression,the impact of social support for the aged on the health situation and the life satisfaction is also investigated.It is shown that the aged in urban areas,getting more social support than those in rural areas,are healthier and more satisfied to life.We demonstrate that the formal social support only has positive effect on the life satisfaction of the aged,but limited effect on the health situation.As for informal social support,we find that young generation’s financial support has little effect on both health situation and life satisfaction of the aged,while the emotional support would bring great benefits to both health situation and life satisfaction.Therefore,the government should strengthen the construction of social security system,the family and society should show great concern to spiritual needs of the old,and emphasize the prevention of chronic diseases so as to improve their health situation and level of life satisfaction.
