英文摘要：
  During its history, the ultimate goal of economics has been to develop similar frameworks for modeling economic behavior as invented in physics. This has not been successful, however, and current state of the process is the neoclassical framework that bases on static optimization. By using a static framework, however, we cannot model and forecast the time paths of economic quantities because for a growing firm or a firm going into bankruptcy, a positive profit maximizing flow of production does not exist. Due to these problems, we present a dynamic theory for the production of a profit-seeking firm where the adjustment may be stable or unstable. This is important, currently, because we should be able to forecast the possible future bankruptcies of firms due to the Covid-19 pandemic. By using the model, we can solve the time moment of bankruptcy of a firm as a function of several parameters. The proposed model is mathematically identical with Newtonian model of a particle moving in a resisting medium, and so the model explains the reasons that stop the motion too. The frameworks for modeling dynamic events in physics are thus applicable in economics, and we give reasons why physics is more important for the development of economics than pure mathematics. (JEL D21, O12)   Keywords: Limitations of neoclassical framework, Dynamics of production, Economic force, Connections between economics and physics.

中文摘要：
在其历史上，经济学的最终目标一直是开发类似于物理学中发明的经济行为建模框架。然而，这并没有成功，目前的流程状态是基于静态优化的新古典主义框架。然而，通过使用静态框架，我们无法对经济量的时间路径进行建模和预测，因为对于成长中的企业或即将破产的企业来说，不存在正的利润最大化生产流。由于这些问题，我们提出了一个动态的理论，用于调整可能是稳定的或不稳定的利润寻求企业的生产。这是重要的，目前，因为我们应该能够预测未来可能破产的企业由于COVID-19流行病。利用该模型，我们可以将企业破产时刻作为几个参数的函数来求解。所提出的模型在数学上与牛顿模型（粒子在阻力介质中运动）相同，因此该模型也解释了停止运动的原因。因此，物理学中的动态事件建模框架适用于经济学，我们给出了为什么物理学对经济学的发展比纯数学更重要的原因。（JEL D21，O12）关键词：新古典主义框架的局限性、生产动力学、经济力量、经济学和物理学之间的联系。
