摘要/Abstract

摘要： 个税递延型商业养老保险政策的实施将对不同收入层次和不同收入来源人群的养老保险模式选择产生重大影响,而我国现行以累进型为主的个人所得税制度在这一影响发生的过程中发挥着根本性作用。基于这一影响机制,本文重点研究EET模式商业养老保险的受益群体范围,以不同收入水平和不同收入来源的杭州市居民为研究对象,以包含社会养老保险和商业养老保险的动态养老金总替代率期望值为调节目标,构建包含个人所得税的累进税率和比例税率变量的保险精算模型,设计和测算了投保期内的下临界点S₁和上临界点S₂。在此基础上,从居民购买商业养老保险意愿度和社会公平的角度出发,探讨对两个临界点的进一步调整,分析EET模式商业养老保险受益群体范围以外人群的行为决策,并最终提出政策性建议。

Abstract: The implementation of the individual income tax deferred type of private endowment insurance policy will have a significant impact on the selection of endowment insurance for groups of different income levels and sources, and China's current personal income tax system, which is mainly progressive, plays a fundamental role in this process. Based on this influence mechanism, this paper uses Hangzhou residents with different income levels and sources as the research object to study the benefit groups under the EET model of private endowment insurance. Aiming at adjusting the dynamic pension replacing rate including basic endowment insurance and private endowment insurance, we design and calculate the lower critical point S₁ and the upper critical point S₂ within the insured period. On the basis of above, from the perspective of the willingness of residents to buy private endowment insurance and social fairness, we explore the further adjustment of the two critical points, analyze the behavior decision mode of the groups which are outside the range of the benefit groups under the EET model of private endowment insurance, and finally put forward the policy suggestions.
