本文认为社会保障作为收入再分配的重要手段之一,是对人均社会福利收入分配的补充与调整。本文采用相对平均差的基尼系数方法对我国社会保障差异化程度进行离散型数据分析,发现我国社会保障基尼系数值较高,但总体上有缩小趋势,其中,主要表现在养老保险与其他社会保险项目发展的不平衡性与区域差异性。所以应进一步加强全民养老保险与医疗保险制度建设,促进工伤、失业保险制度的协同发展,建立全国统筹的社会保障制度,协调各社会保险项目的平衡发展关系对于缩小社会保险基尼系数有重要现实意义。

The problem about the Gini coefficient of income distribution expanded in China has been widely analyzed and identified.But it is deficient to research on the Gini coefficient of social security,based on the income redistribution theory.Social insurance,as one of important means in complementarity and adjustment process of income redistribution,plays an important role in social welfare resources allocation.In this paper,we used the relative mean difference method to calculate the Gini coefficient,to measure the statistical dispersion of our social insurance for discrete data analysis.It was found that the Gini coefficient of our social insurance has a high level value,and in general,decreased with time,which mainly manifests the uneven development and regional differences between Basic Pension Insurance and other social insurance programs.Therefore,we should further strengthen the national Basic Pension Insurance and Medical Insurance system establishment,set up a national co-ordination system of social insurance,coordinate the balanced developing relations of the social insurance programs,inreducing our Gini coefficient of income redistribution,which has important practical significance.
