摘要

我们开发了干散货航运部分货运市场的市场情绪措施。首先，通过对行业利益相关者进行两次调查，确定了具有积极和消极情绪内涵的关键词，并估计了它们的相对重要性。接下来，我们开发了一个自主开发的搜索算法软件，扫描了2008年至2018年期间的9500多篇航运报刊文章，以计算关键词的频率。在构建情绪测度之后，用联立方程组对其有效性进行评估。其中，我们的实证结果表明市场情绪与海运经济活动之间存在双向关系。研究结果对航运业从业者具有重要意义。

Development of a sentiment measure for dry bulk shipping

ABSTRACT We developed a market sentiment measure for freight markets of the dry bulk shipping segment. Initially, keywords with positive and negative sentiment connotation were identified, and their relative importance was estimated, by administering two surveys with industry stakeholders. Next, a self-developed search algorithm software was developed to scan over 9,500 articles in shipping press, during 2008–2018, in order to calculate keywords’ frequencies. Following the construction of the sentiment measure, its validity was assessed with a system of simultaneous equations. Among others, our empirical results indicate a bidirectional relationship between market sentiment and maritime seaborne economic activity. The findings yield important implications for practitioners in maritime shipping industry.

期刊介绍： Thirty years ago maritime management decisions were taken on the basis of experience and hunch. Today, the experience is augmented by expert analysis and informed by research findings. Maritime Policy & Management provides the latest findings and analyses, and the opportunity for exchanging views through its Comment Section. A multi-disciplinary and international refereed journal, it brings together papers on the different topics that concern the maritime industry. Emphasis is placed on business, organizational, economic, sociolegal and management topics at port, community, shipping company and shipboard levels. The Journal also provides details of conferences and book reviews.
