Abstract

China's shipping industry has undergone significant changes driven by evolving government policies. While previous research has largely overlooked a comprehensive analysis of China's shipping policies, this paper offers a systematic exploration of industrial policies from 2010 to 2023. Using a comprehensive dataset of central regulations and applying the Latent Dirichlet Allocation (LDA) model for topic mining, the study provides a detailed examination of key policy trends and the evolving focus of government attention. The findings highlight the increasing emphasis on green and intelligent transformation, alongside the strategic importance of ports as logistics hubs, with a push for modernization and multimodal transportation. The study also notes the government's focus on ship operation management and port facility expansion, supported by tax and financial incentives to enhance international trade. China is transitioning toward a green, intelligent, and efficient development path, aligned with evolving socio-economic conditions. These emerging themes are expected to guide future policy directions.

中国航运政策的演变与关注：来自LDA分析的证据

在政府政策的推动下，中国航运业发生了重大变化。虽然以往的研究在很大程度上忽视了对中国航运政策的全面分析，但本文对2010年至2023年的产业政策进行了系统的探索。本研究利用中央法规的综合数据集，并应用潜在狄利克雷分配（LDA）模型进行主题挖掘，详细分析了关键政策趋势和政府关注焦点的演变。调查结果显示，随着现代化和多式联运的推进，绿色和智能化转型日益受到重视，港口作为物流枢纽的战略重要性也日益凸显。该研究还指出，政府将重点放在船舶运营管理和港口设施扩建上，并辅以税收和财政激励措施，以促进国际贸易。中国正在适应社会经济发展形势的变化，逐步走上绿色、智能、高效的发展道路。这些新兴主题预计将指导未来的政策方向。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
