Bibliometrics of social media research: A co-citation and co-word analysis

This study combined two bibliometric analysis methods to provide a systematic and holistic review of social media-related academic literature. A total of 406 publications related to social media between 2007 and 2016 were identified from 16 business and hospitality/tourism journals. Co-citation analysis identified Word-of-Mouth as the major theoretical foundation of social media research in business, while the hospitality/tourism field presented a diverse theoretical foundation. The study then employed co-word analysis to identify the evolution of research themes over time in both fields. The comparison of social media research between the two fields highlighted four similarities, including the growth of research over time, the term “social media” gaining popularity, the new trend of social networking sites, and managerial applications as research focus. Finally, the study called for a future research agenda on social media research in the hospitality/tourism field.     

Four decades of airline productivity and efficiency studies: A review and bibliometric analysis

Airline productivity and efficiency have remained an area of tremendous interest among both academics and industry analysts since the Airline Deregulation Act of 1978 was enacted in the United States. This paper provides a bibliometric analysis of airline productivity and efficiency studies during the period from 1979 to 2020. The results show that the Journal of Air Transport Management, Transportation Research Part A, and Transportation Research Part E were the top three outlets preferred for publications in this area during the study period, and productive authors were likely to produce influential works. Research interest in airline productivity and efficiency has spread to encompass more diversified geographical regions over time, and new researchers from a broad range of fields continue to become interested in this field of research. Data envelopment analysis and stochastic frontier analysis are shown to be the most popular methods used by researchers, and studies are increasingly attempting to incorporate undesirable outputs, such as carbon emissions, flight delays and accidents, into the measurement and analysis of airline performance. The results from this study can provide guidance for future research issues and directions.     

农作物秸秆综合利用政策保障研究——基于24个省61个县《农作物秸秆综合利用项目实施方案》的文本分析

目的 为提高我国农作物秸秆综合利用水平,完善农作物秸秆综合利用政策保障体系,推动我国农业绿色发展,对我国当前农作物秸秆综合利用政策实施热点展开研究并提出完善对策。方法 文章通过选取近3年来我国24省61县农作物秸秆综合利用政策实施方案,基于内容分析法和共词分析法借助社会网络分析工具UCINET64.0,对我国当前农作物秸秆综合利用政策支持热点、支持对象、支持方式和支持水平进行量化分析和综合评价。结果 （1）当前农作物秸秆综合利用政策支持热点主要集中在技术培训、项目补助、收储运体系建设等方面;（2）当前政策支持对象主要是农户和提供秸秆综合利用服务的社会化服务组织,存在政策支持对象与政策实施对象主体错位问题;（3）当前政策支持方式以环境型政策工具为主,存在环境型政策工具过密、供给型政策工具运用缺乏创新和需求型政策工具运用不足的问题;（4）当前政策支持水平较低,存在政策支持清晰度低、操作性差、同质化强的问题。结论 为进一步提高我国农作物秸秆综合利用政策保障水平,从政策工具上应加快以环境型政策工具为主转向多种政策工具协调运用,从政策实施上应及时调整补贴项目与补贴主体的时序匹配关系。     

Mapping the evolution of the impact of economic transition on Central and Eastern European enterprises: A co-word analysis

Here we use co-word analysis on extant literature to map the intellectual structure of research addressing the impact of economic transition on Central and Eastern European enterprises during the 1989–2013 period. We collected and analyzed 2053 scholarly papers from the most comprehensive management databases, which were then used to develop. This paper contributes to the economic transition literature by providing an empirically derived framework based on the extant literature. This framework describes the main factors affecting enterprises during the transition process, the relationships among these factors and their evolution.     

中国科技评价研究演进脉络与特征——建国70年来相关研究文本分析

以2 698篇中国科技评价研究相关文献作为分析样本，运用共词聚类分析法和社会网络分析法，构建不同研究阶段高频关键词谱系图和共词网络，探究不同研究阶段主题内容和变化趋势。总体而言，研究主题共性与差异并存；评价原则与导向发生了重大转折；评价主体较为单一；评价对象范围不断扩大，分类评价成为新趋势；评价方法日趋多样化；研究关联度和相互渗透性有所增强。在此基础之上，研究发现既有文献在科技评价主体、客体、指标体系构建、评价方法等层面尚存在一些局限性和空白。     

A review of restaurant research in the last two decades: A bibliometric analysis

The present paper presents the results of a bibliometric analysis of published academic research dealing with restaurants in the fields of hospitality, leisure, sport and tourism. In particular, it aims to identify the structure of relationships between previous and current themes, predict emerging trends and provide a longitudinal perspective on this research, covering the period 2000–2018. This approach provides an exhaustive analysis for the past two decades from over 700 papers.The findings show, for example, that customer satisfaction is the motor theme with the greatest impact and the study of emotions is an underdeveloped theme; interest in healthy eating is witnessing gradual growth; and brand equity, culture and innovation all constitute new research themes. The future of research dealing with restaurants will tend to focus on new emerging technologies, both in the restaurant sphere and in the context of research methodologies.     

How much finance is in climate finance? A bibliometric review,critiques, and future research directions

This study describes and analyses the research hotspots and evolution trends in climate finance research. Seven literature clusters that elucidate how different perspectives constitute the research landscape in climate finance and two main research hotspots that form the climate finance domain are identified. The empirical results also show that the research priorities of climate finance are still less “finance-based”. In the future, finance scholars should pay more attention to the financial dimension of climate finance. Finally, the research gaps within the existing climate finance literature are identified, and 35 research questions for future research are proposed.
