英文文献：Estimating Heterogeneous Primal Capacity and Capacity Utilization Measures in a Multi-Species Fishery-估计多物种渔业的不同原始容量和容量利用措施
英文文献作者：Felthoven, Ronald G.,Horrace, William C.,Schnier, Kurt E.
英文文献摘要：
We use a stochastic production frontier model to investigate the presence of heterogeneous production and its impact on fleet capacity and capacity utilization in a multi-species fishery. Furthermore, we propose a new fleet capacity estimate that incorporates complete information on the stochastic differences between each vessel-specific technical efficiency distribution. Results indicate that ignoring heterogeneity in production technologies within a multi-species fishery, as well as the complete distribution of a vessel's technical efficiency score, may yield erroneous fleet-wide production profiles and estimates of capacity.
我们使用一个随机生产前沿模型来研究多物种渔业中异质生产的存在及其对船队能力和产能利用的影响。此外，我们提出了一个新的船队运力估计，该估计包含了各船技术效率分布随机差异的完整信息。结果表明，忽略多鱼种渔业生产技术的异质性，以及船舶技术效率分数的完全分布，可能产生错误的全舰队生产概况和估计能力。
