| With the rapidity of population aging process, the elderly pension and medical needs are both going increasingly unmet. As the social insurance for protection of rural elderly pension and medical needs, social pension insurance systems for urban and rural residents as well as the new rural cooperative medical care highly need an enhancement. Thus, this research seeks to explore the pattern of retirement pension payment by taking relevant data in Anji. More broadly, I hope to contribute to give full play to both two insurance systems.Based on scientific hypothesis, sufficient data cleaning and strict data selection, this research estimates the replacement rate of social pension insurance system for urban and rural residents in Anji, as well as the basic living expenses of the elderly over 60, and evaluates the effects of social pension insurance system for urban and rural residents. Furthermore, microcosmic data of the new cooperative system are combined to measure medical expenses of elderly of all ages in Anji.This research is guided by above-mentioned evaluation. In doing so, I am directed to construct the model of system optimization under the dynamic adjustment, by linking the basic pension insurance of social system with elementary medical expenses of elderly, on a broader theoretical plane, this research serves as an opportunity to conclude the age-segmented pattern of retirement pension payment. I hope to not only conduct the policy simulation in allusion to the model, in combinations with predictor of aging population quantity over 60 from 2015 to 2020, but also to figure out the basic retirement pension payment, the replacement rate of elementary pension and government expenditure. Finally, it might be tempted to conclude that the effect of social pension insurance system would get improved by using the model of system optimization, taking no risk of exerting pressure upon government expenditure. |
