Abstract: Using the spatial OD model，this study analyzes the migration flows among 31 provinces in China by exploring geographical effects，driving mechanism，and gender differences based on the inter-provincial migration data of the 6th Population Census． Inter-provincial migration exhibit significant spatial dependence，in which the origin and destination separate spatial autocorrelation promotes migration， whereas the origin-destination joint spatial autocorrelation hinders migration． In general， the “push”from origin is weaker than the “pull”from destination in Chinese inter-provincial migration．
There are significant gender differences in the driving mechanism． Impact of driving factors on female migration is stronger than that for male migration． Unemployment risk and employment discrimination are more evident in female migration． Males are more strongly influenced by spatial dependence than
females in the choice of migration destination， which could be explained by the gender differences of endowment and social environment．
