基于改进的ELESM法的城市居民最低生活保障标准测算——以山西省为例

Calculation of Urban Minimum Living Guarantee Standard Based on Improved ELESM——Taking Shanxi Province as an Example

从城市低保标准人均可支配收入替代率、城市低保标准消费支出替代率和城市低保标准食品支出替代率三个指标来看,山西省城市居民最低生活保障标准水平明显偏低。文章采用扩展性线性支出系统模型法(ELESM)和需求的收入弹性概念,将城市人均可支配收入等比例分组,构建起测算城市低保标准更为适宜的方法。研究结果表明,基于ELESM法测算的山西省城市低保标准在低保对象的基本生活保障方面有了很大的提高,基本可以满足低保对象的生活需求,大大缩减了他们与其他群体的差异,而且不会给山西省的财政造成负担。

The three urban minimum living guarantee standard indicators of annual per capita disposable income of urban households replacement rate, consumption replacement rate, and food replacement rate suggested that the level of urban minimum living guarantee standard in Shanxi province was obviously low. This paper used the improved extended linear expenditure system method （ELESM） and the concept of income elasticity of demand to build more suitable method for the calculation of the urban minimum living guarantee standard. Research results show that urban minimum living guarantee standard of Shanxi province based on the improved ELESM calculation can meet the basic needs of life for the poor and do not exceed the local financial capacity.
