摘要
避开市场处于均衡态的假设和边际成本等于边际收益的条件,研究了具有Markov转换的LotkaVolterra随机竞争系统下市场结构的变化,指出在各种随机因素的干扰之下,构成系统的各种产品的数目终将随机的分布在各自的均衡点附近,并在一定条件下证明了市场结构的随机最终有界性和渐近性.
In this paper,the evolution of stochastic competitive market structure in the Lotka-Volterra system with the Markov switching is investigated without the conditions of the market in equilibrium hypothesis and marginal cost equal to marginal revenue,it is illustrated that the number of a variety of products consisting of system has a random distribution near the respective equilibrium point.In addition,the random eventual boundedness and progressive of market structure are proved under the certain conditions.
