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n维具有Markov转换的Lotka-Volterra随机竞争系统下市场结构的演进.在各种随机因素的干扰下,构成系统的各种产品的数目终将随机的维持在各自市场份额的均衡点,随机竞争系统是随机持久的,也是依分布渐近稳定的.
The evolution of random competition market structure under Lotka-Voherra system with Markov switching is investigated without the conditions of the market in equilibrium hypothesis and marginal cost equaling to marginal revenue. Under all kinds of random disturbance, the number of various products consisting of system will be randomized to maintain market share of equilibrium respectively, the stochastic permanence and asymptotic sta- bility in distribution of the system are derived.
