本文将博弈论中的混合策略概念与基本经济学概念和生物量动力学模型相结合，以捕捉渔业合作系统的重要方面。将折现的概念假定为鱼类种群内在增长率的函数，并应用于模拟渔民的合作倾向。在不同情况下，每个渔民的捕鱼利润都是由合作倾向贴现的，并被视为一个2乘2的矩阵博弈，有两个参与者和两种策略（合作和非合作）。矩阵中的收益决定了博弈的均衡结果。结果表明，内在生长率和种群规模等生物参数对渔民的合作有重要影响。
The concept of mixed strategies from game theory is combined with basic economic concepts and a biomass dynamics model to capture important aspects of a fishery cooperative system. The concept of discounting, which is assumed to be a function of the intrinsic growth rate of the fish stock, is applied to mimic the fishers’ tendency to cooperate. Profits from fishing, discounted by the tendency to cooperate, are specified for each fisher under various circumstances and viewed as a two by two matrix game, with two players and two strategies (cooperative and non-cooperative). The payoffs in the matrix determine the equilibrium outcome for the game. The results indicate that the biological parameters, intrinsic growth rate and stock size, can have important influence on the fishers’ cooperation.
