Based on the data by area from 2004 to 2010,this paper established a panel model of climate change on the death rate in China,making use of piecewise function as the proxy variable. We find that the death rate-temperature curve can be shaped by U curve,which is higher in the right than left. The lowest death rate appears from 5℃ to 10℃. At high temperature the germs can destroy immune defenses easier,so it leads to the higher death rate. Regional economic development impacts the death rate obviously,as the increase of per capita GDP reaches ten thousand RMB,the death rate goes down by 0. 1342people/one thousand people. The key factor to reduce the death rate is quality of life and medical conditions of service. In the end,we make six kinds of extension of the basic model,and find that the model has good robustness.
