|Abstract The rational thinking assumption by main stream economics has a far distance from real people. This paper designs a series of behavioral economic experiments (trust, prisoners’ dilemma, public good, dictator and ultimatum games) and conducts them in two university classrooms of China and USA. It shows that people intrinsically have goodness and social thinking, and can provide public goods voluntarily and have fair preference of economic interest distribution. However, the American students show higher trust degree and cooperation level, and stronger preferences of cooperation and fairness than the Chinese ones. Therefore, this paper suggests that policy makers are necessary to fully understand people’s social thinking and micro behavior and they are necessary to emphasize on publicizing this kind of thinking, ability and action, and should provide information platform for people to solve collective dilemmas voluntarily.
