Corporate social responsibility and service quality provision in shipping firms: financial synergies or trade-offs?

This study examines whether the implementation of corporate social responsibility (CSR) and provision of service quality (SQ) to satisfy shippers result in financial synergies or trade-offs for shipping firms. To address this question, a contingency framework was introduced in this study. The literature was first reviewed for hypotheses development, followed by interviews with eight industry practitioners. Subsequently, an internet survey was administered to 156 shipping firms in Singapore, and the obtained data were analysed using path model analysis and simple slope analysis. The results indicate that CSR complements SQ and provides additional but modest financial contribution to shipping firms via customer satisfaction. In addition, synergistic interactions between SQ and CSR were found. Although there are financial synergies from the implementation of CSR and provision of SQ, the analysis reveals that CSR should only be engaged when a shipping firm is fairly competent at delivering quality shipping services. This paper contributes to both theory and practice by framing business decisions on implementing CSR under contingency theory and offering a strategic approach to managing SQ as well as CSR of shipping firms.     

基于社会力模型的邮船舱段疏散滞后性分析

针对邮船遭遇紧急事件时乘客疏散过程中的滞后问题,基于社会力模型并应用逐段分析法分析在不同情景下的人员疏散过程。计算结果表明,随着滞后时间的增长,舱室内乘客的疏散效率逐渐降低。最危险的情况是在疏散开始时滞后3个舱段,人员疏散有效时间在平均疏散时间中占比不及50%,总时间是无滞后疏散的2倍。研究方法对邮船及其他类型客船的人员疏散流线设计具有一定的参考意义。
