摘要：
In this paper, three kinds of DEA model are employed, which are CCR, BCC and FG models 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 at the year of 1999, 2005, 2007, and the other years are inefficient. It is also found that if the scale is inefficient, returns to scale of fishery production is increasing, which implies the industry should increase input to improve efficiency.
