我国在人均收入还不高的情况下就开始进入老龄化社会，给我国经济社会的发展带来非常深刻的影响。本项目首先计划研究老年人劳动力供给的变化对家庭其他成员劳动力供给的影响，本项目其次计划研究老年人劳动力供给的变化是如何影响家庭内部的资源配置，本项目最后计划研究老年人人口的增加对家庭内部时间分配的影响。本项目的研究结果不仅仅对评估现有的政策（比如新农保）有重要意义，对于制定未来的政策（比如延迟退休年龄）也有重要的参考意义。除此之外，本项目的研究结果还可以验证理论上关于家庭行为的两个模型，具有学术上的创新。最后，本项目的研究结果对于其他相关政策（例如农村合作医疗）的评估和制定也有重要参考意义。

China has faced the process of fast population aging when the income per capita is still low, which has profound impacts on different aspects of the social and economic development. The first question this project plans to study is the impact of the change in old people's labor supply on the labor supply of their family members. The second question this project plans to study is how the change in old people's labor supply affects intrahousehold resource allocation. Finally, this project plans to investigate the impact of the increase of old people on the time allocation within household. The results of this project have potential implications not only for evaluating the existing policies, such as new rural pension system, but also for making new policies, such as extending the retirement age, in the future. Moreover, results from this project can provide useful reference for other relevant policies such as rural medical insurance policy.
