峰值法和数据包络分析法在中国远洋鱿钓渔业方面的应用与比较分析

概述了PTP和DEA法的基本理论，并将其应用于我国的远洋鱿钓渔业，结果表明，1999年我国北太平洋鱿钓渔业的“捕捞能力”尚未得到充分的发挥，仍有潜力可挖；影响西南大西洋鱿钓渔业“捕捞能力”的主要因素是制冷能力，钓机数，集鱼灯和水下灯，而船长，船舶总吨位，功率和舱容仅为次要因素。通过应用，本文分析比较了这两种方法的特点；PTP法长于在时间序列方面的一个纵向的分析，能够在一定程度上反映渔业技术和资源随时间的变化而发生的变化，而DEA法则擅于在捕捞单位间进行横向的“能力”比较，并能对影响“捕捞能力”的因素进行有效的灵敏度分析。

The application of PTP and DEA methods to fishing capacity measurement of Chinese squid jigging fleets and the comparative study of the two methods

This paper outlined the theories of FTP and DBA methods and applied them to the Chinese fishing fleet of squid jigging. The authors pointed out that Chinese squids jigging fleets in north Pacific have not fully utilized their fishing capacity. The results also showed that the main factors affecting the fishing capacity of the squid jigging fleet in Southwest Atlantic were refrigerating capacity, amount of sets of jigging machines, lights and under-water lights for attracting squids. However, other factors, such as the length of ship, gross tonnage, power and hold capacity, were the minor factors affecting the fishing capacity. By comparing the results using PTP and DBA methods, it can be seen that PTP method is good at the analysis on time series because it can reflect the variations in the technology and the resources of fishing to a certain extent. But DBA method is skilled in the comparison of fishing capacity between a lot of fishing units and can also make sensitivity analyses of the factors which have affected the fishing capacity.
