Regarding the housing consumption, previously traditional researches have put excessive emphasis on social-level fairness, which has difficulties in reflecting the micro individuals characteristics and basic demands in fairness. From the subject perspective of housing consumption, this paper firstly constructs the 4-dimension conceptual model of housing consumption fairness; then, based on 516 samples of Changsha City, it proceeds exploratory researches and gets 4-dimension model, i. e. input fairness perception, output fairness perception, environment fairness perception, and identity fairness perception. With confirmatory researches, this paper also verifies the validity of this newly-constructed 4-dimension model. In view of the constructed model, the migration level of residents has significant moderating effects on the dimensions of input fairness perception and output fairness perception.
