党的二十大报告指出要着力扩大内需,增强消费对经济发展的基础性作用。如何有效刺激居民消费,扩大本国消费需求成为值得研究的问题。因此本文基于预防性储蓄等理论,运用2010年~2022年我国31个省(市)的面板数据,对社会保障支出与居民消费支出两者间关系进行实证研究。研究结果得出:社会保障支出对居民消费具有显著促进作用,并且其对农村居民的促进作用大于城镇居民,此外其对居民消费的影响存在地区差异和保障类型差异。因此,为刺激居民消费扩大本国消费需求,应不断完善社会保障体系,扩大社会保障覆盖率,实现社会保障服务均等化供给,提高居民可支配收入。The report to the 20th National Congress of the Communist Party of China pointed out that we should focus on expanding domestic demand and enhancing the basic role of consumption in economic development. How to stimulate residents’ consumption effectively and expand domestic consumption demand has become a problem worth studying. Therefore, based on theories such as preventive savings, this paper uses panel data from 31 provinces in China from 2010 to 2022 to conduct an empirical study on the relationship between social security expenditure and household consumption expenditure. The results show that social security expenditure has a significant promoting effect on residents’ consumption, and its promoting effect on rural residents is greater than that on urban residents. In addition, its impact on residents’ consumption is different in different regions and different types of security. Therefore, in order to stimulate residents’ consumption and expand domestic consumption demand, the social security system should be continuously improved, the coverage rate of social security should be expanded, the equal supply of social security services should be realized, and the disposable income of residents should be increased.
