中国老年家庭的经济脆弱性与贫困

Economic Vulnerability and Poverty of Elderly in China

利用中国健康与营养调查(CHNS)2006和2009年的面板数据测度了老年家庭的经济脆弱性,检验各因素对经济脆弱性和贫困的相对影响力。老年家庭的经济脆弱性高于贫困;户主特征和家庭变量不同程度地影响到了经济脆弱性及贫困,代际间向上流动的私人转移支付对老年家庭的经济脆弱性和贫困没有作用;超过24%的非贫困家庭是经济脆弱性家庭;期望效用的脆弱性(VEU)方法表明,不平等虽然减少了脆弱性,但其影响经济脆弱性的力量最小,不可解释的风险是最重要的因素,异质性风险和协同性风险的力量居中。

Using panal data 2006 and 2009 of the China Health and Nutrition Surveys（ CHNS）, this paper measures the extent of vulnerability, examines the relative importance of its different determinants. Vulnerability of elderly is higher than poverty. The characteristics of household and household head have different effect on vulnerability and poverty,while upstream intergen erational private transfers have no effect on vulnerability and poverty. There is 24% of the households observed to be non poor are vulnerable to poverty. With expected utility approach （VEU） ,The decomposition shows that poverty decrease vulnerability, but poverty account for the smallest share, unexplained risk account for the largest share, whereas that from idiosyncrat ic and covariate risks is moderate.
