Abstract
The objective of this study is to develop a structural model that can be used to explain consumer adoption intentions for electric automobiles in Vietnam. This research investigated the following independent variables: attitudes, subjective standards, perceived behavioral control, and personal moral norms, vehicle performance, purchase price, charging infrastructure, government incentives, environmental concern, and product knowledge. Between June 4, 2022 and August 30, 2022, we received 327 replies to our online survey. Before being included to the database, the collected surveys undergo a second screening. Due to the fact that all observable variables had identical values, eight replies were considered invalid. In the end, 319 replies satisfied the requirements of this research. This study used the Linear Structural Relation Model (LISREL) and the regression model to test hypotheses and create the research model. According to the data, is 0.626, Adjust is 0.614, and there is a perfect match in the LISREL model with /df close to 0.000 and p-values close to 1.000. When testing hypotheses, both models yielded identical results: Only subjective needs, charging infrastructure, and product knowledge have no substantial effect on the adoption intentions of electric vehicles among consumers. Other independent variables strongly impact customers' adoption intentions for electric vehicles. This paper also contains recommendations for the electric vehicle industry, government, and future researchers.
