There have been many studies about why the voluntary migrants migrate,while few are about the moving attitudes,the moving difficulties and other moving dynamics involved in development induced migration(or project affected migration).The reason for such a situation is that we take these problems for granted and needn′t be discussed since the migration is under government administration. However,through one case analysis of a development induced migration,we have found that the factors,which may have influences on the motivation of such a migration,are more complicated than those of an voluntary migration.These factors can be divided into the cost benefit ones and the none cost benefit ones.The former also determines the outcomes of a voluntary migration decision,which include monetary cost(benefit),psychological cost(benefit)and so on.The latter only related with development induced migration,which include such factors as the justness,the constraint and the participation of the influenced people,all of them are involved in the interaction between government and migrants.And that′s where we can find the potential in migration mobilization task when the compensation is given the same.
