constant returns to scale

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。

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。

Take the lead in adopting the imperfect competition and scale of economy assumptions instead of perfect competition and constant returns to scale .

率先用不完全竞争和规模经济假设替换原模型的完全竞争和固定规模报酬假设。

We introduce the constant returns to scale model and changed returns to scale model of DEA , and clarify the economic significance of the models .

介绍了数据包络分析的固定规模报酬模型（C2R）和变动规模报酬模型（BC2）的建立过程，阐明了模型的经济意义。

The perfect combination between the good nature of the production function of constant returns to scale and perfect competition is necessary to prove the legitimacy of the marginal distribution theory , which was widely seen as proof of the legality of the market economy .

而生产函数规模报酬不变的良好性质与完全竞争的完美结合，则为证明边际分配理论的合法性起了重要的作用，这也被广泛地认为是市场经济合法性的证明。

On one side , from the DEA analysis of the Outputs Inputs of Science Technology between 1995 and 2000 , a conclusion is drawn that , in HuBei , for most years , technological productions have been comparatively effective , however , with constant even decreasing returns to scale .

一方面，通过对湖北省1995-2000年科技投入产出的DEA分析，得出了湖北的科技活动在大多数年份里相对有效，但规模收益不变、甚至递减的结论；
