Technical efficiency, Dutch beam trawl fleet, Common Fisheries Policy, stochastic production frontier
使用随机生产前沿方法分析荷兰底拖网船队的技术效率，发现船体大小和配额可转让性提升效率，而船龄、渔具限制和总允许捕捞量导致的丢弃率则降低效率；效率随资源丰度下降而降低，但渔区限制通过减少拥挤反而改善效率。
The technical efficiency over time of the Dutch beam trawl fleet is examined using a stochastic production frontier. Factors increasing efficiency are found to be vessel size and improved quota transferability, whereas vessel age, gear restrictions and total allowable catch implying a higher discard rate have a negative impact. Average technical efficiency falls with decreases in stock abundance relative to the EU fleet size, but improves with fishing area restrictions, possibly through the reduction in crowding arising from a more dispersed fishing activity. The results suggest that EU fleet reduction programmes could result in a less than proportional decrease in harvesting capacity and that fleet replacement programmes associated with the reduction programmes may, to a large extent, offset the capacity reductions Keywords: technical efficiency, Dutch beam trawl fleet, Common Fisheries Policy, stochastic production frontier
