摘　　要：研究单一企业群体及两个企业群体进行产量竞争情形下,企业组织模式选择的演化问题.假定企业可以选择集中化模式或分散化模式,对于封闭经济情形,建立了单种群演化动态,并证明了当替代系数满足一定条件时,存在惟一的演化均衡.在此基础上,以所得的演化均衡为初始条件建立了两种群演化模型,研究了开放经济下企业同时进行国内和国际竞争时其组织模式的演化,理论分析和数值例子表明不存在稳定的内点演化均衡.通过比较不同贸易政策下的均衡产量和均衡利润,阐释了演化均衡的动态调整过程.The evolutionary problems for organizational mode choice of firms where one population and two populations of finns compete in quantity are studied. The finns are assumed to choose either centralized mode or decentralized mode and the replicator dynamics of one population is presented under autarky. It is demonstrated that there exists a unique evolutionary equilibrium when substitute coefficient satisfies certain conditions. Furthermore, with the autarky evolutionary equilibria taken as initial conditions, the model of two populations is built to study the evolution of organizational mode under the environment that the firms compete at home and abroad. Theoretical analysis and numeri- cal examples show that there is no stable interior evolutionary equilibrium. Finally, the dynamic process of evolutionary equilibria is illustrated by comparing the equilibrium output and equilibrium profit under different trade policies.
