基于LDA主题模型的渔业限额捕捞管理政策研究
Research on China's fisheries Total Allowable Catch management policy based on LDA topic model
摘要
Abstract
The Total Allowable Catch(TAC)management system is one of the internationally important fisheries management policies,playing a crucial role in the sustainable utilization of fishery resources.This study uses the Latent Dirichlet Allocation(LDA)topic model to identify the in-depth content themes and latent semantics of Chi-na's TAC policies,and further analyzes the evolution of these themes.The results indicate that China's TAC pol-icies have undergone three stages:the initial stage,the rapid development phase,and the refinement stage.It is currently in the refinement stage.The themes identified include four categories:"Fishery Resource Conservation and Sustainable Utilization""Implementation and Management of TAC Policies""Multi-dimensional Strategies for TAC Policy Enforcement""Sea Area Management and Ecological Protection".The major turning point for all four themes occurred in 2015,marking a watershed when TAC policies focus transitioned from"conceptualization"to"practical implementation."The study suggests that while a preliminary institutional framework has been estab-lished,it requires continuous dynamic adjustments in response to evolving management needs.Corresponding im-provement recommendations are proposed based on the identified issues.This research clearly delineates the cur-rent status,thematic structure,and evolutionary trends of China's TAC policies,providing valuable references for future policy formulation and related research.关键词
