MEL是一份同行評審的季度科學出版物，致力于全球供應鏈的方法分析，即海洋運輸、港口、海運碼頭和海運物流。論文將被徹底研究，科學嚴謹，同時對從業者和政策制定者有直接的適用性和有用性。通常，MEL在標題“政策視角”下包含一個特殊的部分。這里的論文，往往是征求意見，強調戰略政策的影響，而不是嚴格意義上的科學嚴謹。從政策角度看，論文受到的同行評議較少，這導致出版速度更快。作為國際海事經濟學家協會（IAME）的官方刊物，MEL始終處于海事經濟學和物流前沿學術研究的前沿。

MEL is a peer-reviewed quarterly scientific publication committed to the methodological analysis of global supply chains; that is, ocean transportation, ports, marine terminals and maritime logistics. Papers are expected to be thoroughly researched, scientifically rigorous and at the same time of direct applicability and usefulness to practitioners and policy makers alike.Often, MEL includes a special section under the heading ‘Policy Perspectives’. Papers here, often solicited ones, emphasise strategic policy implications rather than scientific rigour in a strict sense. Papers in Policy Perspectives are subject to lighter peer review and this results in speedier publication.As an official journal of the International Association of Maritime Economists (IAME), MEL is always timely at the forefront of cutting edge academic research on maritime economics and logistics.
