我们开发了带有因素约束的矩形技术选择模型（RCOT），这是一种用于分析单个地区经济的线性规划投入产出模型。它允许一个或多个部门同时运行多种技术，如果遇到约束因素约束，成本相对最低的一项技术将由其他技术进行补充。 RCOT 模型解决了部门产出、由使用中成本最高的技术决定的商品价格，以及与较低成本技术所经历的约束因素约束相对应的稀缺租金。该模型的动机是，不同质量的矿藏可以同时开采，相同材料的初级和回收来源或生产相同作物的灌溉和雨养技术也可以同时开采。 RCOT 概括了卡特的方形技术选择模型，特别是添加了允许多种替代方案同时运行的因素约束。附录给出了一个数值示例。
We develop the rectangular choice-of-technology model with factor constraints, or RCOT, a linear programming input-output model for analysis of the economy of a single region. It allows for one or more sectors to operate more than one technology simultaneously, with the relatively lowest-cost one supplemented by others if it encounters a binding factor constraint. The RCOT model solves for sector outputs, goods prices that are set by the highest-cost technologies in use, and scarcity rents that correspond to binding factor constraints experienced by the lower-cost technologies. The model is motivated by the fact that mineral deposits of different qualities may be exploited simultaneously, as may primary and recycled sources for the same materials or irrigated and rain-fed techniques for producing the same crop. RCOT generalizes Carter's square choice-of-technology model, in particular adding the factor constraints that allow several alternatives to operate simultaneously. The Appendix gives a numerical example.
