Abstract: Exploratory and confirmatory factor analysis was used to verify the double-dimensional bipolar theoretical structural model of self-interest preference and social preference. The double-dimension in the model structure refers to the first-order double factors that constitute the preference matrix: social preference and self-interest preference. The social preference includes three sub-dimensions of altruism preference, reciprocity preference and inequality aversion, and the self-serving preference includes self-interest and rationality. In addition, the survey of 1,143 college students of 12 different disciplines and another 747 subjects of this study from 9 different occupations found that: 1) The group preference of pedagogical students and teachers belongs to the preference of “strong altruism-fairness” and “weak selfishness-rationality”; 2) The preference types of economics majors and banking service professionals belong to the preference of “egoism-rationality” and “weak altruism-fairness”; 3) Medical students and doctors belong to “altruism-reciprocity” preference; 4) Law students and lawyers belong to “reciprocity and fairness” preference; 5) Police and firefighters belong to the “altruistic rational” preference; and 6) Private business owners belong to the “mutual-self-interest” preference. The preferences of other disciplines and occupations were not obvious.

Key words: self-interest preference, social preference, two-dimensional bipolar model
