摘要

In this paper, The three models of DEA are employed, which are CCR, BCC, and FG model, respectively, to analyze the scale efficiency and returns to scale of industry of fishery production in Zhejiang province from 1999 to 2008. It is found that the scale is efficient only in the years 1999, 2005, 2007, the other years it is inefficient. It is also found if the scale is inefficient, returns to scale of fishery production are increasing, which imply the industry should be increased input to improve scale efficiency of fishery production.
