| Abstract: | In this paper,the existence of positive equilibrium and stability conditions were given as to a class of discrete predator-prey system with capture.In the semi-open resources,we considered the influence of flexible price and variable cost to capturing efforts. Using Gordon theory and the government tax policy we got the stability conditions with the economic equilibrium point and gave the optimal acquisition strategy. |
