DEA Duality on Returns to Scale (RTS) in Production and Cost Analyses: An Occurrence of Multiple Solutions and Differences Between Production-Based and Cost-Based RTS Estimates
讨论数据包络分析中生产与成本分析框架下的规模报酬概念，聚焦多重解问题及其处理方法，并理论探讨基于生产与基于成本的规模报酬估计之间的对偶关系。
This article discusses the concept of RTS (Returns To Scale) in the framework of DEA (Data Envelopment Analysis) production and cost analyses, focusing on an occurrence of multiple solutions and how to deal with such a difficulty. Dual relationships between production-based and cost-based RTS estimates are also theoretically discussed in this study.
