荷兰梁拖网船队的技术效率随着时间的推移进行检查使用随机生产前沿。提高效率的因素被认为是船只大小和改进的配额可转让性，而船龄、渔具限制和总可捕量（意味着较高的弃鱼率）则有负面影响。平均技术效率福尔斯随着相对于欧盟船队规模而言的种群丰度的减少而下降，但随着捕鱼区的限制而提高，这可能是由于捕鱼活动更加分散而减少了拥挤。结果表明，欧盟船队削减方案可能会导致捕捞能力的比例下降，与削减方案相关的船队更换方案可能会在很大程度上抵消能力的下降。版权所有2001年，牛津大学出版社。
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.
