The trail of halal services research: the bibliometric analysis using R

Purpose This paper aims to present a review and analysis of the literature on halal services over 25 years. The number of publications on halal services has increased over the years in the fields of business, management and economic research; however, the topic has been discussed less comprehensively in relation to bibliometric analysis. Design/methodology/approach This study was conducted using review and bibliometric analysis. In total, 346 articles were extracted using a modified Preferred Reporting Items for Systematic Review and Meta-Analyses procedure, and 176 documents were eliminated because they were not within the scope of the Halal Services topic. Finally, 170 articles were analyzed using the Biblioshiny-Bibliometrix R package. Findings Research on halal services has grown steadily over the past 25 years. Most studies were conducted in Muslim countries; however, some non-Muslim countries, such as the United Kingdom and China, also contributed to the topic of halal services. Thematic analysis revealed that most halal services papers are categorized under the “Niche Theme” or the “Basic Theme.” Research limitations/implications This study contributes by providing future researchers with knowledge and information on knowledge structures and state-of-the-art halal services. This study also provides insights into the development of novel ideas that may contribute to expanding the research on halal services worldwide. Originality/value This study provides a comprehensive analysis of halal services research using bibliometric analysis. Through this method, this study attempts to summarize the trends in halal service research over 25 years, which may suggest future research directions into halal services.
