In recent years, the concept of sustainable consumption behavior (SCB) is largely introduced and changed continuously to be discussed with industries such as energy sector, agriculture, transportation, sharing economy, and tourism. However, the study of sustainable consumption behavior in the online education industry (SCBOEI) remains a research gap. Thus, this paper aims to identify the significance of sustainable consumption behavior and theoretically conceptualize SCBOEI. This study employs content and text analysis to reconceptualize the major theories that contribute to the research of SCB. The findings in this study show that SCBOEI is contributed of great significance to promote sustainable development. In addition, this study introduces a model of SCBOEI, in which the consumer value theory, social exchange theory, and planned behavior theory are integrated. Additionally, this paper suggests that value, environmental attitude, identity, consumer engagement, and contextual factors (government behavior, market conditions, and environmental education) are highly important to extend the research on SCBOEI. In conclusion, this study strongly recommends that SCB research shall be directed to the online education industry. Furthermore, future studies shall emphasize the empirical effects of psychological factors, activity factors, and contextual factors for SCBOEI to find the correlation.

Higher education for sustainable development (HESD) in the Covid-19 pandemic faces different challenges. Empirically few studies to date have introduced much on the digitalization of higher education for sustainable development. This study aims to explore and explain the digitalization of HESD from different attitudes and to build linkages of the digitalization in HESD. Furthermore, the study makes content analysis where 1,200 tweets on digitalization in higher education for sustainable development are collected from Twitter, and 19 documents have further categorized information data via NVivo. In addition, 22 students and 9 instructors were invited for a semi-structured interview to further supplement this study and confirm its findings. This study finds that attitudes towards digitalization in the study area can be divided into three correlated attitude layers. Teaching attitudes and educational attitudes are the first level, and the second level is the digital platform attitude, technology use attitude, and resource attitude. Furthermore, network attitude, service attitude, and development attitude are the third level. Thus, through the analysis, this study suggests higher education institutions should make improvements in digitalized teaching, education quality via innovation, technological development, resources use, and development via creating a better digital platform or environment is essential for genuinely promoting the HESD.

Digital tourism is an essential product of the digital economy, which is significant in promoting sustainable tourism. The study aims to analyze the current research status of digital tourism with the CiteSpace tool. One thousand thirteen documents related to digital tourism, AI tourism, and tourism digitization in the Web of Science (WOS) database from 1991–2022 were collected. This study conducts bibliometric analysis to portray the knowledge map. Furthermore, this paper explores the publication years, co-occurrence of authors, institutions, subjects, research hotspots, and evolution of digital tourism research. The analysis findings revealed that social and environmental sciences are the core disciplines in digital tourism research. Hong Kong Polytechnic University is the foremost institution, and Tussyadiah and Wirtz are the authors with the highest contribution rate. Moreover, the results emphasized the frontier studies of digital tourism referring to technology, consumption, tourists’ reviews, and the progress of the tourism industry. In addition, China, Europe, and the United States should strengthen their digital tourism cooperation with Africa and the South America to promote the sustainable development of global tourism. Finally, the results implicate the future development trends of digital tourism.

The prosperous development of online education in the digital age harvested countless consumers. Education for sustainable development is an important proposition for both academic community and practitioner, however, current little studies have shed light on Sustainable Consumption Behavior in online education industry (SCBOEI). The Consumer Value Theory and Social Identity Theory as theoretical basis linked with the field of Sustainable Consumption Behavior. This study is to further investigate the role of consumer value and social identity in the relation to Sustainable Consumption Behavior. Putting forward suggestions from this study to online education providers toward sustainable development.MethodData on the impact of personal value on SCBOEI through a survey method with 552 valid students as respondents are collected from higher education institutions in China. A structural equation modeling approach is employed in this study for data analysis.ResultsThe result shows at the level of excellent model fit as indicated by all indicators: X2/DF = 1.053 (<3), RMSEA = 0.010 (<0.08), CFI = 0.991, GFI = 0.971, TLI = 0.989, AGF = 0.961 (>0.9). The results showed that, through social identity, functional value (indirect effect = 0086, P < 0.001), emotional value (indirect effect = 0061, P < 0.001), and social value (indirect effect = 0.073, P < 0.001) influence the variance of SCBOEI. The finding reveals that both theories can explain the SCBOEI of higher education students by showing that functional, social, and emotional values as well as social identity are powerful predictors of the Sustainable Consumption Behavior. The proposed model highlights the mediating role of social identity between SCBOEI and the three values. The functional, emotional, and social values influence SCBOEI directly and through social identity.ImplicationsThe study significantly contributes to market promotion, college students, education planning, and teaching. Online education market personnel and college students can better understand the significance of sustainable development aspect of online education. Teaching and learning activities help lead students to SCBOEI by shaping their values and identities while paying more attention to quality education, knowledge sharing, and social equality.
