Compartmental models are widely used in epidemiology, engineering, and physics to describe the temporal behavior of complex systems. This paper presents how compartmental models may be applied to the digital economy—more specifically, how the Bass model can be extended to more complex economics systems such as markets with customer churning, competition, multisided platforms, and online games. It is demonstrated that it is straightforward to establish the equations describing the various economic systems under study, however, the equations are often too complex to be solved analytically in the general case. Though the paper presents simple and idealized cases, the solutions may, nevertheless, uncover important strategic aspects that otherwise may be hidden by complexity in the general case, for example, the reasons for slow initial market growth. The paper also discusses how the developed models may be used to evaluate digital economic market evolution and business policy.

区室模型广泛用于流行病学、工程学和物理学中，以描述复杂系统的时间行为。本文介绍了分区模型如何应用于数字经济——更具体地说，巴斯模型如何扩展到更复杂的经济系统，例如具有客户流失、竞争、多边平台和在线游戏的市场。事实证明，建立描述所研究的各种经济系统的方程很简单，但是，这些方程通常过于复杂，无法在一般情况下进行解析求解。尽管本文提出了简单和理想化的案例，但解决方案可能会揭示重要的战略方面，否则这些方面可能会被一般情况下的复杂性所掩盖，例如，初始市场增长缓慢的原因。
