Introduction
The convergence of "Halal Tourism" and "Sustainability" has emerged as a vital subject of investigation within the worldwide tourism domain.There is a growing interest among scholars and practitioners in the convergence of several factors, which is indicative of the wider socio-economic and environmental issues that are inherent in modern tourist practices.In recent years, an increasing amount of scholarly work has emerged to comprehend the intricacies and consequences of halal tourism within a global context that is becoming more aware of the need for sustainability.Several recent studies have contributed to the understanding of halal tourism and its relationship with sustainability.Keliat and Sentanu (2022) conducted an integrative review that synthesized the existing knowledge base and literature on this topic.Battour et al (2021) critically assessed the connection between halal tourism and sustainability.Rahmat (2021) conducted a literature review specifically focusing on halal tourism within the social science disciplines.Additionally, Rusydiana et al (2021) conducted a bibliometric study that examined the indicators associated with halal tourism.Previous research has examined the prospects of halal tourism in several settings, including Malaysia, Singapore, and Ethiopia, and has analyzed the determinants that impact halal tourism (Abbasian, 2021).These studies emphasize the significance of researching halal tourism and sustainability to comprehend the various economic, social, environmental, and cultural aspects of this business and its influence on society and the environment.
Considering the increased scholarly activity in this field in recent years, there exists a strong rationale for undertaking this bibliometric analysis.The extant body of literature, exemplified by prominent scholarly works such as Keliat and Sentanu (2022), Battour et al. (2021), Rahmat (2021), and Rusydiana, Abbasian (2021), has established the foundation for comprehending the complex interplay between halal tourism and sustainability.The research has analyzed the knowledge foundation, evaluated the interaction between these aspects, investigated halal tourism across other fields within the social sciences, and even scrutinized the factors influencing this industry.
Hence, it is imperative to conduct a thorough bibliometric analysis to catch these nascent trends and evaluate their scholarly influence.This analysis has the potential to offer valuable insights into the strengths and limitations of publications in the field of halal and Islamic tourism.Additionally, it can serve as a guide for future research endeavors in this area.In this study, we aim to investigate the effects of a new drug on patients with a Furthermore, it has the potential to provide a more comprehensive comprehension of the methods to create halal-friendly places, drawing insights from the viewpoints of millennials (Suban et al., 2021).A systematic review and thematic analysis might address the existing gaps in the literature by examining the accumulating evidence on halal tourism (Idris et al., 2022).
A recent scholarly investigation conducted by Abdullah et al., (2023) undertook the task of charting the cognitive terrain about the intersection of halal tourism and sustainability.This comprehensive analysis encompassed an examination of prevailing research trajectories, thematic foci, and patterns of authorship within this domain.The purpose of this study was to conduct a bibliometric analysis of publication patterns in the field of halal tourism.The analysis attempted to assess many aspects including research topics, sources with high publication output, highly cited documents, co-authorship patterns, and bibliographic coupling.The study was conducted by Abdullah (2021).Adirestuty et al., (2023) conducted a bibliometric analysis to investigate scholarly literature about the management of halal tourism from 2012 to 2021.The objective of the study conducted by Rusydiana et al., (2021) was to analyze the bibliometric indicators of halal tourism to ascertain the research landscape and progress in this field as reflected in publications from esteemed scholarly journals.
There has been an increasing focus on subjects such as digital marketing within the context of halal tourism, the socio-cultural aspects of halal tourism experiences, and the formulation of sustainability measures specifically designed for halal tourism locations (Hanafiah et al., 2022).According to Battour et al., (2021), the existing body of research on halal tourism mostly focuses on the demand-side aspect, hence necessitating an examination of halal tourism from the supply-side standpoint.The examination of halal tourism's growth in Indonesia has been analyzed through a supply-side approach, focusing on the concepts of Place Attachment and Value-Norm-Belief, as explored by Dewi (2023).The phenomenon of halal tourism destinations has witnessed a notable surge in international arrivals on a global scale.This has led to a competitive environment among both Muslim and non-Muslim countries, as they strive to appeal to Muslim visitors (Suryandari et al., 2022).
Nevertheless, the dynamics of the field are undergoing tremendous evolution.The emergence of new research paths and the deepening of existing ones have created a need for a complete bibliometric study to capture these evolving trends.The rationale for conducting this study is rooted in the objective of offering a contemporary overview of the intellectual terrain about the intersection of halal tourism and sustainability.This study seeks to utilize bibliometric tools to discern new trends, influential books, and shifting research orientations.
Moreover, the objective of this study is to provide a comprehensive international outlook on this discourse by broadening the focus to include a wide array of countries and cultural situations.The motivation behind this study stems from the aim to encourage interdisciplinary involvement, acknowledging the complex relationship between economic, cultural, and environmental aspects within the realm of halal tourism.
Bibliometric analyses have played a crucial role in enhancing comprehension of the relationship between halal tourism and sustainability.Nevertheless, a significant deficiency remains in the thorough examination of emerging research trends and growing research orientations within this interdisciplinary domain.Numerous bibliometric studies have provided useful information about publication trends, influential authors, and research issues.Suban et al., (2021) conducted a bibliometric analysis of halal and Islamic tourism, wherein they assessed the global literature using a bibliometric approach that incorporated several features.The study not only provided insights into the existing body of knowledge but also offered guidance for future scholars intending to explore this field.
Contemporary scholarly literature indicates a growing scholarly inclination toward interdisciplinary inquiry that delves into the complex dynamics between cultural, economic, environmental, and social dimensions of halal tourism and sustainability (Suban et al., 2021& Hanafiah et al., 2022).
Nevertheless, there is a notable deficiency in bibliometric research that thoroughly examines the interconnections between different disciplines and their respective contributions to our comprehension of this intricate domain.Although prior research has laid a strong groundwork, it is possible that it does not comprehensively cover the swiftly evolving academic environment, particularly given recent advancements, and developing issues (Suban et al., 2021).
Therefore, the aims of this study are as follows.First and foremost, it aims to conduct a bibliometric analysis of scholarly research on halal tourism and sustainability, focusing on patterns and research output.The analysis will encompass all relevant scholarly papers, categorizing them by document and source type, year of publication, language, subject area, and the most frequently cited source titles.The study will cover the period from 2015 to 2023.Furthermore, the primary goal is to examine clusters within two co-occurrence networks by analyzing keywords from the publications and exploring co-occurrence patterns of these keywords, along with terms found in the titles and abstracts of the articles.Lastly, the study seeks to provide a comprehensive analysis of research patterns at the intersection of halal tourism and sustainability, with a specific focus on the geographical distribution of published works and the authorship of these publications.
The subsequent sections of the paper are categorized into five distinct parts: Section 2 provides a concise overview of the existing literature about the intersection between halal tourism and sustainability.Section 3 provides an in-depth examination of the technique employed in the present study.Sections 4 and 5 provide a comprehensive explanation of the data analysis and outcomes, accompanied by a detailed conclusion and suggestions.
