Since China’ s reform and opening up，connections between the regions in China are getting increasingly closer，with more and more frequent population migration．The reason why people migrate from one region to another is because of the attraction of the inflow area．This paper uses the 6th national population census data and the attractiveness measurement indicator RIA to calculate the attraction index for China’ s 31 provinces．The result shows that the east coastal zone，which represented by Guangdong，Zhejiang，Shanghai， Jiangsu and Beijing，has the largest attraction for migrants．On the other hand，the far west region，defined as restricted development region，which represented by Gansu，Qinghai，Ningxia and Tibet，has the least attrac- tion for migrants．Policy implications are discussed regarding industrial upgrading，population control，environ- mental protection，and targeted poverty alleviation．
