Using survey, we discuss how climate and environmental issues awareness affects residents’ low carbon use behaviour. The results are following. Firstly, climate and environmental issues awareness positively affects residents’ low carbon use. Secondly, perceived effectiveness has mediate effect on the relationship between climate and environmental issues awareness and low carbon use behaviour partly. Thirdly, perceived value has negative moderate effect on the relationship between climate and environmental issues awareness and low carbon use conduct. The results of this study show that when residents feel higher perceived value about their low carbon consumption, they will engage in low carbon use even with lower climate and environmental issues awareness. It tells us that we should treat the residents differently with classification when advocate low carbon use. Specifically, there are some product and service in which consumers can gain high perceived value if the residents frugally use them with high efficiency. And we need to make effort to the following things: we improve the perceived value with hard working, and on the other hand, we make enough effort to enable the residents to deeply experience the perceived value via multiple means.

While data-driven digital technologies (e.g., mobile applications) have brought convenience to users, they have also raised data privacy concerns. Regulators have taken various actions that ensure user data privacy to balance the protection and exploitation of personal data. However, the effect of privacy regulatory protection in preparing mobile users for data sharing remains unclear. This research develops and empirically tests an integrative model of how mobile users adjust their intention to share personal data in response to privacy regulatory protection. The results indicate that privacy regulatory protection can increase users’ intention to share personal data through enhancing psychological ownership of data (i.e., entitlement effect) and decreasing privacy concerns (i.e., reassurance effect). Moreover, the entitlement effect can be attenuated as app control over data increases, while the reassurance effect can be accentuated as users’ privacy efficacy increases. This research provides new insights into the role of privacy regulatory protection in promoting user data sharing by highlighting the psychological mechanisms underlying users’ responses to such regulations. It provides implications for digital platforms seeking to balance the challenges of user data protection with the benefits of data-driven marketing.
