我们研究由相互作用的单元组成的系统的动力学，每个单元具有包含许多子单元的复杂内部结构，并处理每个子单元以乘法方式增长的情况。我们提出了此类系统的模型，其中单元之间的相互作用以平均场近似进行处理，并且子单元之间的相互作用是非线性的。我们测试了该模型，并根据跨度 20 年的大型经济学数据库找到了我们的预测与实证结果之间的一致性。
We study the dynamics of a system composed of interacting units each with a complex internal structure comprising many subunits and treat the case in which each subunit grows in a multiplicative manner. We propose a model for such systems in which the interaction among the units is treated in a mean field approximation and the interaction among subunits is nonlinear. We test the model and find agreement between our predictions and empirical results based on a large economics database spanning 20 years.
