摘要翻译：
我们提出了一个简单的熊彼特经济动力学定量模型。新的商品和服务是通过现有商品的组合而内生产生的。新商品一进入市场，就可能与现有商品竞争，换句话说，新产品可能对现有商品产生破坏性影响。由于这种竞争机制，现有的商品可能会被赶出市场--往往会造成一连串的次生缺陷（熊彼特式的毁灭风暴）。该模型导致了一种普遍的动态，其特点是经济相对稳定的阶段，然后是市场大规模重组的阶段----这可以解释为熊彼特的商业“周期”。产品多样性和生产率的模型时间序列在长时间尺度上再现了经济学时间序列中的一些程式化事实，如GDP或企业失败，包括非高斯厚尾分布、波动性聚类等。该模型是在一个开放的、非平衡的环境中描述的，可以理解为一个自组织的临界系统。它的多样性动态可以通过主动生产网络的时变拓扑来理解。

英文摘要：
  We propose a simple quantitative model of Schumpeterian economic dynamics. New goods and services are endogenously produced through combinations of existing goods. As soon as new goods enter the market they may compete against already existing goods, in other words new products can have destructive effects on existing goods. As a result of this competition mechanism existing goods may be driven out from the market - often causing cascades of secondary defects (Schumpeterian gales of destruction). The model leads to a generic dynamics characterized by phases of relative economic stability followed by phases of massive restructuring of markets - which could be interpreted as Schumpeterian business `cycles'. Model timeseries of product diversity and productivity reproduce several stylized facts of economics timeseries on long timescales such as GDP or business failures, including non-Gaussian fat tailed distributions, volatility clustering etc. The model is phrased in an open, non-equilibrium setup which can be understood as a self organized critical system. Its diversity dynamics can be understood by the time-varying topology of the active production networks.
