社会保障对城镇居民消费的影响研究——来自CGSS2010的经验分析

The Impact of Social Security on Urban Household Consumption——Empirical Analysis from CGSS 2010

基于CGSS 2010年的家庭微观调查数据,应用分位数回归模型实证分析社会保障对中国城镇居民消费的影响。研究结果显示:在同等消费水平下,参加社会保障城镇居民的边际消费倾向要高于未参加社会保障者;不同收入组城镇居民的边际消费倾向大致呈"几"字形,即高收入组居民和低收入组居民的边际消费倾向较低,而中等收入居民的边际消费倾向较高;此外,参加社会保障居民的边际消费倾向随着年龄增加呈现明显的递减趋势,而随着受教育程度的提高呈现上升趋势。

Based on the mirco survey data of household from CGSS 2010, the paper empiri- cally analyzes the impact of social security on urban household consumption by using quantile re- gression model. The main findings are as follows： Firstly, when consumption level keeps the same, the marginal propensity to consume of urban residents with social security is higher than that of urban residents without security. Secondly, the marginal propensity to consume of high - in- come and low - income urban residents is lower than that of the middle - income urban residents. Thirdly, the marginal propensity to consume of urban residents decreases with their age increase while it increases with their education level.
