在Bak-Sneppen动态中异质政治/环境条件下经济实体的演变
Evolution of economic entities under heterogeneous political/environmental conditions within a Bak-Sneppen-like dynamics
摘要：
建立了一个非均匀空间经济条件下的经济行为模型。利用蒙特卡罗模拟研究了选择压力在具有实体扩散的类Bak-Sneppen动力学中的作用，并考虑了企业间的短程区位“相互作用”、企业分拆或合并的商业计划以及企业生存演化规律等商业规则.数值计算发现，该模型导致一种相变的适应间隙作为选择压力的函数。
英文摘要：
A model for economic behavior, under heterogeneous spatial economic conditions is developed. The role of selection pressure in a Bak-Sneppen-like dynamics with entity diffusion on a lattice is studied by Monte-Carlo simulation taking into account business rule(s), like enterprise - enterprise short range location "interaction"(s), business plan(s) through spin-offs or merging and enterprise survival evolution law(s). It is numerically found that the model leads to a sort of phase transition for the fitness gap as a function of the selection pressure.
