Carbon dioxide emissions from port container distribution: Spatial characteristics and driving factors

Port carbon dioxide (CO₂) emissions in China have become an ever-increasing public concern due to their significant impacts on human health and the environment. However, existing studies focus mainly on CO₂ emissions from vessels calling at the ports and cargo handling within the ports, paying little attention to the inland distribution networks. To fill this gap, this paper proposes an easily implemented method for calculating CO₂ emissions from port container distribution (PCD) and investigates their spatial characteristics and driving factors. By analyzing 30 container ports in China, the main findings are as follows. First, road transportation is the major contributor of CO₂ emissions from PCD due to the lack of rail and inland water transportation. Second, PCD carbon emissions exhibit significant local spatial clustering. That is, ports with similar geographical locations tend to present a similar pattern of PCD carbon emissions. Third, as suggested by the spatial Durbin model, PCD carbon emissions are negatively determined by local gross domestic product, number of port berths, but are positively determined by local tertiary industry value and highway freight volume, and waterway freight volume in both local and neighboring ports. These results provide empirical insights into cross-port collaboration in reducing PCD carbon emissions.     

Association rule learning to improve deficiency inspection in port state control

ABSTRACT

The inspection of foreign ships in national ports is a critical measure in port state control (PSC), preventing substandard ships from entering national ports. Multifarious inspection items, limited inspection time and inspector manpower are challenging PSC inspection. This research applies data mining to analyze historical PSC inspection records in Taiwan’s major ports to extract potential valuable information for PSC onboard inspections. Using the Apriori Algorithm, the analysis identifies many useful association rules among PSC deficiencies in terms of specific ship characteristics, such as ship types, societies, and flags. The general rules identified show that the items ‘Water/Weathertight conditions’ and ‘Fire safety’ are significantly related. Besides, in the analysis of the various ship types, several different rules are found. After comparing the analysis of ship types and ship societies, it can be observed that the association rules for specific ship types, such as oil tankers, have a better effect than those for individual ship societies do. These identified rules can not only help inspectors effectively spot the associated deficiencies, but also improve the efficiency of PSC inspection. The ports other than Taiwan’s ports can apply a similar analysis method to identify corresponding association rules suitable for their own inspections.     

关于建立宁波液化品自由港的探讨

宁波港是世界著名的深水良港,自然条件得天独厚。宁波液化品自由港位于中国的炼化产业带,区位优势明显,硬件设施先进,管理规范,是国内吞吐能力最大的液化品专业港。由于缺乏良好的关税环境,宁波液化品港在与韩、日港口的竞争中处于劣势。鉴此,就建立宁波液化品自由港的意义、条件和发展进行了探讨,以期为建立宁波液化品自由港,为我国液化品运输的发展和我国炼化行业的降本增效提供参考。

我国港口国监督法律制度的不足及相关完善建议

港口国监督是海洋安全的最后防线,受到世界各国的重视。然而目前,我国港口国监督的实施与其航运大国的地位极不相符,相关法律不健全,导致一方面在很多问题上无法可依,另一方面现有法律法规对我国港口国监督缺乏实际的指导意义,本文重在分析我国港口国监督相关法律制度的不足并在此基础上,提出一些完善建议,希望能对我国港口国监督法律制度的完善有所裨益。
