An indispensable role in promoting the electric vehicle Industry: An empirical test to explore the integration framework of electric vehicle charger and electric vehicle purchase behavior

Extensive research on electric vehicle charging infrastructure has been conducted within the field of electric vehicle purchase behavior, yet home electric vehicle charging infrastructure remains largely unexplored. This research expands the Combined Technology Acceptance Model and Theory of Planned Behavior through a series of three studies, each involving data collection at two different time points. The research focused on the psychological mechanisms underlying the use of personal electric vehicle chargers and electric vehicle purchase behavior as well as the types of personal chargers used in communities. The findings have crucial theoretical and practical implications for the development of electric vehicles as well as green management policies and strategies to achieve sustainable development. Interestingly, while government subsidies policy enhances the positive relationship between intentions to purchase electric vehicles and the actual purchase behavior, the green product information asymmetry will attenuate this positive linkage. This research provides new insights into the relationship between reducing greenhouse gas emissions and achieving net-zero carbon emissions EV purchase behavior, highlighting the complex interplay between EV purchase behavior, government subsidies, and green product information asymmetries.
