本文在介绍社会保障研究和多区域CGE进展的基础上,提出将社会保障研究从传统的单区域局部均衡框架推进至多区域一般均衡的研究框架,并构建了一个中国多区域社会保障可计算一般均衡模型(Multi—Regional,MReCGE—C),该模型对居民根据城乡属性和年龄结构进行了分组,放松了要素流动的限制,使劳动力和资本可以同时跨区域流动,并设计了一种基于居民终生效用的区域均衡机制,通过区域变量可以调控和测度区域差距。最后利用MReCGE—C模型针对中国社会保障政策下的两种典型方案进行了模拟。
In this paper, firstly we introduce the progress of social security and CGE. Secondly, we try to improve the research of social security from single - regional and partial equilibrium framework to multi - regional and general equilibrium framework, and then, we construct a multi- regional CGE model of China. In this model, we category the household by urban attribution and age structure, and we design a mechanism of inter - regional equilibrium based on household utility, through which we can control and measure regional disparities. At last, we simulate 2 typical scenarios of social security policy in China.
