Blockchain technology for sustainable development: a systematic literature review

Purpose

Blockchain technology (BCT) is one of the latest disruptive innovations, brought along with-it immense scope of diverse applications contributing towards sustainable development (SD). The consistent increase in the publications reveal that the application of BCT for SD has become popular among researchers and practitioners in past few years, in turn, urged for a systematic literature review (SLR) to get an insight into the research journey travelled so far and setting directions for future research in this area. Therefore, this study aims to identify, map and synthesize the available literature on application of BCT for SD.

Design/methodology/approach

The automatic and manual search resulted into 1,277 studies from Scopus and Web of Science database. Further applying inclusion and exclusion criterion resulted in bringing out total of 157 studies, which were termed as primary studies. Based on the results of descriptive analysis, conducted through Bibliometric and VOSviewer software, the characteristics of BCT and its key capabilities, contributing towards shaping the recent SD literature, were critically examined. Identified research themes for clustering primary studies were aligned with United Nations Sustainability Development Goals (UNSDG). A mind-map was also prepared on the basis of thematic classification of primary studies.

Findings

The research themes “business practice and economic sustainability”, “agriculture and food security” and “business practice and environment sustainability” were found to be the focal points of scholarly attention. Synthesis and analysis of primary studies resulted into classification of research gaps under four categories – theoretical foundation, methodological limitation, research themes and technology implementation challenges. The study was concluded by sensitizing and sanitizing the concrete research questions for future research.

Research limitations/implications

The research findings shall be a roadmap for research scholars, academicians and practitioners to comprehend the present state of knowledge in the domain of “BCT application for SD” and decide upon adopting the future course of action to attain the UNSDGs by the year 2030.

Originality/value

To the best of the authors’ knowledge, the current study is the first attempt in its own sense to analyse and synthesize the available literature on “attaining SD through BCT” using SLR approach.

A critical review of HR analytics: visualization and bibliometric analysis approach

Purpose

This study aims to analyze the existing literature in human resource analytics and highlights the future research agenda and trends in the same context. It deals with evaluating regional distribution, identifying key authors, publications, journals and keyword occurrences while examining current literature.

Design/methodology/approach

A total of 127 articles exported from the Scopus database were systematically analyzed using bibliometric analysis through VOSviewer, including performance analysis and science mapping of the literature studied.

Findings

This research postulates the inconsistency between the number of publications and citations received by an author. There was an increase in collaborative research over the years. Human Resource Management Review was regarded as the most influential journal with maximum citation. Maximum publications came from Asian countries. The study revealed that the author with maximum citation were mostly the first authors of the most cited documents.

Practical implications

This research may be beneficial for both researchers and human resource (HR) practitioners because it identifies the research gaps and research needs in the HR analytics domain. Besides, this study recognizes the patterns in HR analytics literature that helps researchers better understand the subject area.

Originality/value

This research incorporates bibliometric analysis for analyzing HR analytics literature to establish a more exhaustive and systematic understanding of the research area. This research contributes to the existing body of literature and assists fellow researchers in future studies.

Decarbonization strategy of businesses, stock return performance and investment styles: a systematic review

Purpose

This paper aims to provide a systematic review of the research focusing on the decarbonization strategy of businesses, stock return performance, and investment styles.

Design/methodology/approach

The paper utilizes bibliometric methods and content analysis to present a broad overview of the research on the association between decarbonization strategies in businesses and financial performance in the last few decades. The final dataset contains 272 records published between 2001 and early 2021, available in the Web of Science (WoS) database.

Findings

The authors find a relatively small number of publications before 2010 and the research focus increases only after 2016. There exists limited knowledge on the links between climate change strategies and firm performance till date. The top management journals have also failed to respond to the importance of decarbonization strategies in firms and their relationship with stock returns and investment styles. Furthermore, there is a limited indication of publications from ecology and the environmental sciences, in general, being included or cited by the business and management research studies, thus highlighting weak network linkages between the two fields.

Research limitations/implications

The study contributes to the literature on decarbonization strategies of businesses, and the strategies' relation with firm performance by consolidating the extant research and thus finding the research gaps and research areas that require further investigation.

Practical implications

For the industry professionals, this research provides a comprehensive repository of articles on incorporating decarbonization strategies in industry professionals' decisions on improving firm performance.

Originality/value

This paper examines the history and development of themes, related to firms' emission mitigation strategies, firm performance and investment styles, across the journal articles in the WoS database published from 2001 to early 2021. In addition, the authors highlight research directions and the need for research on sustainable strategies in businesses, stock return, and investment styles.

Trajectory of research on maritime transportation in the era of digitization

Purpose

The literature on Maritime Transportation (MT) is experiencing a transition phase where the focus of the research is repositioning. It registered steep growth in recent years with its beginning articles on the concepts of cost minimization to the current focus on achieving sustainable operational effectiveness using Information and Communication Technologies (ICTs). Thus, this becomes a right time to investigate the trajectory of research on MT.

Design/methodology/approach

The proposed study aims to explore the potential of data analytics techniques such as data mining and network analytics to reflect the trajectory of research in the maritime supply chain over time. This study identifies the eight main dimensions of the research published under maritime paradigm through network analytics. The in-depth review of these dimensions rendered us to segregate them further into sub-dimensions for the ease of understanding and interpretability. Further, the text mining is employed to extract thematic evolution of the research.

Findings

The evolved themes are completely exclusive from the conventional MT research with artificial intelligence, digital storage, waste management and biofuels emerging as contemporary themes. It is found that although there are a sufficient amount of literature on sustainable port practices but their policy implications are still underexplored. The inter-dimension research is needed to achieve the motive of economic efficiency and environmental sustainability simultaneously.

Originality/value

The study has contributed on the methodology side of conducting literature reviews. The dimensions, sub-dimensions and themes are obtained using data analytics tools and techniques. This omits the possibility of personal bias and thus making the results verifiable.
