虽然环境扩展投入产出（IO）模型通常用于捕获生态系统和经济系统之间的相互作用，但这种模型无法反映生态系统内部的相互作用。 Isard (1968) 的模型是唯一的例外。他将生态系统内发生的交互输入到 IO 中。然而，考虑到IO的线性，他只能以线性方式分析环境问题。我们提出了一种逆转艾萨德模型类型的替代方案：经济系统在生态系统内建模（而不是相反），作为生态系统的组成部分之一。为了证明其可行性，我们通过将传统经济 IO 集成到系统动力学 (SD) 中来开发生态经济模型。在描述了方法论问题后，我们通过将IO/SD模型应用于鳎鱼生活的法国塞纳河口的破坏和恢复，在生态和经济数据上“测试”了IO/SD模型。我们的模型深入了解了生态系统和经济系统之间相互作用建模中反馈循环的考虑。我们相信这样的工具可能有助于决策者将经济和环境问题结合起来，例如在我们的应用案例中，鱼类栖息地和港口开发。
While environmentally extended input-output (IO) models are commonly used for capturing interactions between ecosystems and economic systems, this kind of modelling cannot reflect interactions within the ecosystem. Isard's (1968) model has been the only exception. He entered interactions occurring within the ecosystem into IO. Nevertheless, given the linearity of IO, he could only analyze environmental issues in a linear fashion. We propose an alternative that reverses Isard's model types: the economic system is modelled within the ecosystem (not the contrary), as one of the ecosystem's components. To demonstrate its feasibility, we develop an ecological-economic model by integrating conventional economic IO within system dynamics (SD). After describing the methodological issues, we “test” the IO/SD model on ecological and economic data by applying it to the destruction and restoration of the Seine Estuary, France, where Common soles live. Our model brings insight into the consideration of feedback loops in the modelling of interactions between the ecosystem and the economic system. We believe such a tool may be of help to decision makers in mixing economic and environmental issues like, in our application case, fish habitat and harbour development.
