摘要翻译：
发展中经济体的企业成长过程会产生成长路径的差异，从而导致规模分布的双峰性。在财富分配中也观察到了类似的双峰现象。在这里，我们介绍了一个修正的动力学交换模型，它可以再现这些特征。特别是，我们将在数值上表明非线性保留率（或储蓄倾向）导致了这种双峰性。该模型既能适应二元交易，也能适应整个系统端的交易，从而更适合于解释财富分布和企业规模分布的非标准特征。

英文摘要：
  Firm growth process in the developing economies is known to produce divergence in their growth path giving rise to bimodality in the size distribution. Similar bimodality has been observed in wealth distribution as well. Here, we introduce a modified kinetic exchange model which can reproduce such features. In particular, we will show numerically that a nonlinear retention rate (or savings propensity) causes this bimodality. This model can accommodate binary trading as well as the whole system-side trading thus making it more suitable to explain the non-standard features of wealth distribution as well as firm size distribution.
