摘要
在寻租博弈框架内建立了具有溢出效应的企业研发投入动态竞争系统,首先进行了局部稳定性分析,在分析了系统在作为可行域基本边界两个坐标轴上的演化特征以后,解析导出了系统整体的可行域边界.研究了系统具有对称和非对称结构时的全局性特征.一定条件下,系统可能出现多个吸引子甚至是混沌吸引子与周期性吸引子并存的现象,这样的多态稳定性使得系统对初始状态极为敏感,因而造成企业研发投入行为具有强烈的路径依赖性特征,即从不同的初始条件出发的系统轨道可能演化进入不同吸引子的吸引域.最后讨论了不同参数条件下市场的竞争形势.
A RD dynamic competition model with spillover effects is established in the rent-seeking framework. The local stability analysis is firstly conducted, evolutionary properties of the system restricted to two axes, which are the basic boundaries of feasible sets, are then analyzed and the whole boundary of feasible sets is determined. Global properties of systems with symmetrical and nonsymmetrical structure are studied. Under some conditions, several attractors may coexist, even chaos attractor and periodic attractor may coexist. The multi-stability makes the system＇s dynamic behavior sensitive to initial conditions, that is to say, different initial conditions may lead the dynamic pro- cess to basin of different attractors. At last, the competing states are analyzed under different parameter conditions.
