Customer Relationship Value in the Business-to-Business Railway Market of Southern Africa by Noanne Botha submitted in accordance with the requirements for the degree of DOCTOR OF ADMINISTRATION in the subject Business Management at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: Prof Peet Venter November 2019 1 DECLARATION Name: Noanne Botha Student number: 55321049 Degree: DAdmin (Business Management) I declare that Relationship Value in the Business-to-Business (B2B) Railway Industry of Southern Africa is my own work and that all the sources that I have used or quoted have been indicated and acknowledged by means of complete references. ________________________ 19 November 2019 Signature: N Botha Date 2 ABSTRACT This study involves establishing imperative customer relationship value anteced- ents and mediators within the business-to-business (B2B) railway industry of Southern Africa and determining whether these relationship value antecedents and mediators will achieve customer retention as an outcome. The goal is to create a conceptual model for the B2B railway industry of Southern Africa, which will be done through reviewing well-established theories and past literature on the topics of relationship marketing, relationship value, and retention within the B2B industry. After an examination of the existing literature, a proposed concep- tual model will be developed and tested using confirmatory factor analysis (CFA) with a sample of 265 B2B supplier companies operating in the Southern African railway market. The CFA represents the measurement model of this research, which proposes the relationship value antecedents, mediators, and their influ- ence on retention within the B2B railway industry of Southern Africa. Secondly, structural equation modelling (SEM) will be conducted, in order to test relation- ships with latent factors. The results indicate that the factors of service, supplier, relational, and financial performance are important antecedents, and that satis- faction and relationship value are significant mediators of customer retention in the B2B railway industry of Southern Africa. KEY TERMS Relationship marketing, Relationship value, B2B railway industry, trust, satisfac- tion, retention, Relationship value antecedents, Relationship value mediators 3 CURRICULUM VITAE OF AUTHOR – N.
