This paper studies the influencing factors of three different decision of rural migrant population: short-term residence, longterm residence and settlement, comprehensively consider the family factors, intervening factors, inflow factors and outflow factors, by using the Multinomial Logistic Regression, with data from China Migrants Dynamic Survey 2017 of the floating population. The results show that: (1) Among family factors, economic conditions and child support needs are the basis of residence decision making. The larger the family size, the more difficult it is to make shortterm residence or settlement decision. (2) In terms of intervening factors, the nearby gradient migration is more conductive to long-term residence and settlement. The accumulation of migration time, the gap of city scale between the inflow and outflow cities and the improvement of family members living together ratio contribute to the longterm residence and settlement willingness. (3) The size of cites, public services and social integration are all important factors affecting settlement. (4) The rural migrant with assets such as homestead and contracted land, and family members tend to stay in the city temporarily.
