Sustainable Supply Chain and its Risk Management: A Systematic Literature Review of Issues and Trends using a Bibliometric and Network Approach

The risks associated with sustainable supply chains (SSCs) have been receiving increasing attention. However, despite increasing research on SSCs, SSC-related risks have not been reviewed satisfactorily or comprehensively. Therefore, we conducted a systematic literature review that incorporated bibliometric, citation network, and keyword network analysis. For this purpose, we selected the top journals in the field of supply chain management and identified 823 related papers in the Scopus database. The analysis revealed the critical issues, topics, and changes over time in research regarding SSC-related risks. Furthermore, we identified specific issues and explored SSC risks via keyword network analysis

Service Quality in Tourism: A Systematic Literature Review and Keyword Network Analysis

The tourism industry has received increasing attention as it has become one of the fastest developing business sectors around the world. Service quality in tourism has come to be regarded as an important impetus for economic growth; however, the focus on tourism service quality has not yet been satisfactorily or comprehensively reviewed. Therefore, we conducted a systematic literature review combining bibliometric, citation network and keyword network analysis. We selected the top five tourism journals from the SCOPUS database and then collected papers according to their keywords. Our results revealed the critical issues, topics, and changes over time regarding research on tourism service quality. The critical issues included the important impact of service quality on tourist behavior and service quality evaluation, and topics comprised (1) tourist satisfaction, (2) sustainable issues in tourism, (3) value of service quality for customers, (4) restaurant service quality, (5) customers’ perceptions of tourism, (6) service quality evaluation in tourism, and (7) service quality’s influence on customer behavior. Furthermore, the keyword network analysis results revealed the most influential keywords

Incentive Mechanism for Sustainable Improvement in a Supply Chain

In this study, we consider the issue of sustainable development in the supply chain consisting of an original equipment manufacturer (OEM) and a contract manufacturer (CM). We investigate how to facilitate the CM’s investment in the environmental quality of a product so as to properly respond to climate change. We introduce a quantity incentive contract, and obtain the optimal solution based on a Stackelberg game. The OEM, as the focal company, determines the level of the incentive, and the CM, responsible for product design and production, determines its level of environmental quality given the OEM’s incentive offer. To investigate the effectiveness of the quantity incentive contract and provide important implications, we analytically compare the quantity incentive contract with the basic wholesale price contract without any incentives and conduct numerical experiments. Our results reveal that the quantity incentive contract facilitates the CM’s investment in environmental quality, and enhances the environmental, market, and profit performance of not only the CM but also the OEM which pays the incentive. We also show that the quantity incentive contract is suitable to develop a long-term relationship between the OEM and the CM
