In the demand-driven open input–output model, output is determined by final demand, given the production technology in every industry. On the contrary, in the supply-sided version, value added determines the level of output and producers must induce sales in order to achieve a desired level of income. This latter version of the model has been criticised and even rejected on its implausibility, its difficult interpretation and its bizarre implications, among other aspects. This paper argues that the supply-side model is not logically, mathematically or otherwise at odds with Leontief’s arguments. Rejection of the model is a matter of theoretical reading.

需求驱动和供应侧投入产出模型

在需求驱动的开放式投入产出模型中，给定每个行业的生产技术，产出是由最终需求决定的。相反，在供给方面，增值决定了产出水平，生产者必须诱使销售才能达到期望的收入水平。该模型的后一版本因其不可信，难以解释以及其怪异含义等方面而受到批评甚至拒绝。本文认为，供应方模型在逻辑，数学或其他方面均与Leontief的论点不一致。拒绝该模型是一个理论阅读的问题。
