Non-radial centralized resource allocation DEA models under constant returns to scale have been studied in this paper.

研究了基于规模报酬不变的非径向集中式资源配置DEA模型。

The Comparative Advantage Theory of David Ricardo is constructed on a series of assumptions including perfect competition and constant returns to scale.

李嘉图的比较优势理论是建立在完全竞争与规模报酬不变等一系列假设条件之下的。

Between the range of minimum and maximum efficient scale of output, there may also exist constant returns to scale where the average unit costs of production remain unchanged as output increases.

在产出的最小与最大有效规模之间，还可能存在规模经济不变的情况，这种情况下随着产量增加，生产的单位成本保持不变。

In the model, the production function is assumed to be nonclassic and constant returns to scale.

该模型的生产函数是满足“新古典”条件的一次齐次函数。
