摘　　要：假定一个渔场有2个渔业公司,分别就Cournot模型和Stackelberg模型研究了2个渔业公司为了各自获得最大持续净收益而投入的捕捞努力量。分析表明:当存在2个捕捞公司时,每个公司投入的捕捞努力量比只有一个捕捞公司时投入的努力量多,但最大可持续净收益不随之增加,甚至还会减少。产生这种后果的原因在于:每个公司只按照自己最优捕捞努力量进行捕捞,而没有考虑其捕捞行为对对方或社会产生的负面影响。This paper supposes that there are only two fishing players, and studies the problem that how they determine their fishing effort in the model of Cournot and model of Stackelberg respectively, with the sake of maximizing the each sustainable net profits. Analysis shows that when there are two fishing companies, although each company will take more fishing effort compared with only having one catch company. The maximum sustainable net profits will not increase, and it even will decrease. The reason for this kind of result lies in each company carries on fishing only according to its own optimal fishing effort and ignores negative influence that its fishing behavior has on the counterpart or the society.
