Post disaster reconstruction is an important job to ensure the return to normal production and life of the people in the earthquake stricken areas. So, how to measure the performance of post disaster reconstruction? Which factors will affect the performance of post disaster reconstruction? This paper reviews the related literature on performance of post disaster reconstruction. On this basis, this paper argues that the effect and efficiency are two major aspects of the performance of post disaster reconstruction. So, using the time spent in eliminating the impact of disasters and returning to the pre disaster level as standard of measuring the reconstruction performance can reflect the reconstruction effect and efficiency. It has feasibility. Based on this, this paper establishes an analytical framework and measurement method for post disaster reconstruction performance. Taking the Wenchuan earthquake, the Yushu earthquake and the Lushan earthquake as the cases, the paper compares and analyzes the reconstruction performance of the three earthquake stricken areas, and briefly analyzes the reasons for the performance differences. The results show that the three earthquake reconstruction basically completed the goal of post disaster reconstruction on schedule, but because of the different degree of disaster, different quality of reconstruction after disaster, there are some differences in the performance of the three post-earthquake reconstruction.
