首先建立了一类食饵依赖型捕食-食饵生态经济模型，并对该模型的生物经济学涵义作了简要说明；接下来运用Routhchurwitz判据对系统平衡点的局部稳定性进行了详细分析，得到了该系统正平衡点的局部稳定性判据；最后通过动力学分析得到了食饵种群持久生存前提下的最大持续收获量，同时探究了该前提下价格随供求变化的经济效益的最大值。

In this paper ,an economic harvesting model of prey -dependent is established .After a bio-economic explanation of the model,we analyze the local stability of positive equilibrium point in detail by routhchurwitz criterion ,and naturally get the criteria for local stability .Maximum sustainable yield is given through dynamics analysis when the permanence of prey is guaranteed.Similarly,the revenue with price changed with demand and supply is studied and the maximum revenue is presen -ted.
