Fishing vessel productivity is an important metric in terms of economic performance, and yields information about the financial impact of policy changes on fishing fleets. In this study, a new method is proposed to measure sector-wide commercial fishery total factor productivity (TFP), and is applied using northeastern United States fishery-level data from 2007 to 2018. Results from the study are linked to changes which occurred after 2006 Magnuson–Stevens Fishery Conservation and Management Reauthorization Act (MSFCMRA). This is accomplished by employing a translog production possibility frontier to measure total outputs, inputs, and TFP using Törnqvist indices. Quality differences embodied in the capital assets are accounted for, and the TFP measurement is adjusted for fishery stock changes. Results show that for most fisheries, improvements in biomass after the MSFCMRA re-authorization led to improved TFP. However, when biomass growth estimates were separated from overall TPP growth, biomass-adjusted TFP annual growth declined about 2% per year. This highlights the importance of separating biomass growth from output growth so managers understand the impact of their policies on the commercial fishing sector separately from biomass growth.

就经济绩效而言，渔船生产率是一项重要指标，它可提供有关政策变更对渔船队的财务影响的信息。在这项研究中，提出了一种新的方法来测量整个行业的商业渔业全要素生产率（TFP），并使用了美国东北部2007年至2018年的渔业水平数据进行了研究。研究结果与之后发生的变化相关2006年马格努森–史蒂文斯渔业保护和管理再授权法案（MSFCMRA）。这是通过使用超量生产可能性边界来使用Törnqvist指数测量总产出，投入和TFP来实现的。考虑到资本资产中体现的质量差异，并针对渔业种群变化对全要素生产率的计量进行了调整。结果表明，对于大多数渔业来说，MSFCMRA重新授权后生物质的改善导致了TFP的提高。但是，当将生物量增长估算值与总TPP增长值分开时，生物量调整后的TFP年增长率每年下降约2％。这凸显了将生物量增长与产出增长区分开来的重要性，因此管理人员可以将政策对商业捕捞部门的影响与生物量增长分开理解。
