摘要
本文使用2001-2014年的省际面板数据,分析了人口流动对地区养老金差距及不平等的影响。使用固定效应模型以及基于回归的不平等分解的结果显示,在控制经济发展水平等变量后,人口流入越多则地区养老金水平越高,人口流动因素扩大了地区养老金的不平等程度。在人口流动常态化的背景下,基本养老保险的地区分割将带来老年风险的"责任转嫁"。人口流入地区获得养老金的"流动人口溢出",而人口外流地区则承担养老金的"流动人口损失"。这种老年风险与保障的错配将极大冲击本就脆弱的欠发达地区的社会保障体系。
This paper uses provincial panel data from the year of 2001 to 2014 and analyzes the impact of migration on regional pension gap and inequality. While controlling the level of economic development and other factors, this paper uses the fixed effect model and regression-based inequality decomposition. It finds that the factor of migration contributes to regional pension inequality, and the level of pension grows as more people flow in. As large-scale migration becomes normal, the regional segmentation of basic social pension system may lead to the transfer of responsibility for old- age-risk from developed regions to underdeveloped areas. While regions with inflows of migration would have the ＂ spillover＂ impact, regions with outflows of migration would experience the ＂migration loss＂ effect. The mismatch between the old-age-risk and social protection will have a great impact on the social security system of those vulnerable underdeveloped regions.
