Mobile payment has played a vital role in transforming traditional payment methods into digital payment methods and has led to changes in consumers’ behaviors in economic exchanges. However, there is a lack of knowledge about how perceived security influences are a sustainable use of mobile payment services. In order to examine the impact of perceived security on users’ continuous use, especially regarding mobile payment services and factors related to perceived security (i.e., perceived control, interface design features, and conscientiousness), an empirical study was conducted to collect data from 252 participants. Then, the proposed research model was examined using structural equation modelling. The results revealed that the perception of interface design features was influenced by conscientiousness. Perceived security was affected by perceived control, the perception of interface design features, and conscientiousness. Moreover, perceived security was identified to have a strong impact on continuous intention to use mobile payment. The design implications for mobile service providers and designers are presented.

As an emerging artificial intelligence system, social robot could socially communicate and interact with human beings. Although this area is attracting more and more attention, limited research has tried to systematically summarize potential features that could improve facial anthropomorphic trustworthiness for social robot. Based on the literature from human facial perception, product, and robot face evaluation, this paper systematically reviews, evaluates, and summarizes static facial features, dynamic features, their combinations, and related emotional expressions, shedding light on further exploration of facial anthropomorphic trustworthiness for social robot design.

Environmental surroundings are highly shaped by consumer choice. Eco-label has been discussed as an effective tool for promoting such environmental product information from the producer to the consumer in relevant literature; however, the young generation has seldom been examined in previous research. Additionally, studies on the structural process of eco-label’s impact on green purchase remain limited, especially the mediation effects within the process. Regarding this research gap, the current study empirically tested the effects of eco-label on product attributes, environmental attitude, environmental concern and consequent purchase behavior from the young Chinese generation perspective. The intermediary role of product attribute is first investigated in the labeling-driven purchase, and the environmental attitude and concern are tested respectively to better understand the young generation’s awareness, compared to previous relevant studies. Based on the appropriate sample collection (N = 699), a structural equation model (SEM) was used, and results statistically showed the impact of eco-label mediated by product attributes on environmental attitude and environmental concern, and how green purchase behavior was influenced through this process significantly. Theoretical contributions and managerial implications are also discussed in this study.

Although China has enjoyed great economic growth in the past several years, environmental problems have not attracted enough attention, especially for the young Chinese population (Generation Z consumers). Based on the theory of planned behavior, this work aims to analyze the mediation role of product attributes, perceived consumer effectiveness (PCE), and environmental awareness in eco-label–informed purchase for Gen Z consumers in China. According to the result, it shows (a) eco-label–informed purchase could significantly increase two threads of PCE and product attributes, (b) those two threads intermediate the eco-labeling and environmental awareness positively, and (c) eventually lead to purchase behavior for Chinese Generation Z. For theoretical contribution, this article tries to have a more comprehensive investigation on green consumption, and to explore the theoretical relationship among product attributes, PCE, and environmental awareness in the context of Chinese Gen Z. Relevant managerial implications and practical guides are also discussed in this article.

Driven by advanced voice interaction technology, the voice-user interface (VUI) has gained popularity in recent years. VUI has been integrated into various devices in the context of the smart home system. In comparison with traditional interaction methods, VUI provides multiple benefits. VUI allows for hands-free and eyes-free interaction. It also enables users to perform multiple tasks while interacting. Moreover, as VUI is highly similar to a natural conversation in daily lives, it is intuitive to learn. The advantages provided by VUI are particularly beneficial to older adults, who suffer from decreases in physical and cognitive abilities, which hinder their interaction with electronic devices through traditional methods. However, the factors that influence older adults’ adoption of VUI remain unknown. This study addresses this research gap by proposing a conceptual model. On the basis of the technology adoption model (TAM) and the senior technology adoption model (STAM), this study considers the characteristic of VUI and the characteristic of older adults through incorporating the construct of trust and aging-related characteristics (i.e., perceived physical conditions, mobile self-efficacy, technology anxiety, self-actualization). A survey was designed and conducted. A total of 420 Chinese older adults participated in this survey, and they were current or potential users of VUI. Through structural equation modeling, data were analyzed. Results showed a good fit with the proposed conceptual model. Path analysis revealed that three factors determine Chinese older adults’ adoption of VUI: perceived usefulness, perceived ease of use, and trust. Aging-related characteristics also influence older adults’ adoption of VUI, but they are mediated by perceived usefulness, perceived ease of use, and trust. Specifically, mobile self-efficacy is demonstrated to positively influence trust and perceived ease of use but negatively influence perceived usefulness. Self-actualization exhibits positive influences on perceived usefulness and perceived ease of use. Technology anxiety only exerts influence on perceived ease of use in a marginal way. No significant influences of perceived physical conditions were found. This study extends the TAM and STAM by incorporating additional variables to explain Chinese older adults’ adoption of VUI. These results also provide valuable implications for developing suitable VUI for older adults as well as planning actionable communication strategies for promoting VUI among Chinese older adults.
