“为己利他”行为机理的社会基础：变和博弈

＂为己利他＂行为机理的形成和施行是以合作剩余的存在这一社会基础为前提的,这也就是变和博弈的情形。正因为人类社会的互动中存在着合作剩余,产生了相互协作以做大共同利益这块蛋糕的动机,由此衍生出＂为己利他＂行为机理。而且,潜在的合作剩余越大,个体越倾向于采取合作的方式,从而＂为己利他＂行为机理越容易产生和扩展。

The Social Foundation for the Behavior Mechanism of "For Oneself by Benefiting Others": Non-Zero Sum Game

The form and practice of the behavior mechanism of ＂for oneself by benefiting others＂ has its social foundation： there are cooperative surplus;i.e.non-zero sum game.Just because there are cooperative surplus among the human interaction,the motive to cooperate with each other to increase the common interest comes into being;further,the behavior mechanism of ＂for oneself by benefiting others＂ drives out.What＇s more,the more the potential cooperative surplus is,the more individual is inclined to take cooperative manner;as a result,the easier the behavior mechanism of ＂for oneself by benefiting others＂ comes into being and extends.
