The Influence of Psychological Factors on Consumer Purchase Intention for Electric Vehicles: Integrating NCA Methodology from the Perspective of Self-Determination Theory

Abstract

This paper examines the impact of psychological factors on consumer purchase intention for electric vehicles (EVs) through the lens of Self-Determination Theory (SDT). By integrating the three dimensions of autonomy, relatedness, and competence, this study addresses a research gap in consumer innovative consumption, offering a deeper understanding within the context of green transportation. The research reveals that psychological factors significantly influence innovative consumption and the purchase intention of EVs, aligning with existing literature. In the realm of sustainable transportation, psychological factors such as motivation, attitude, and inner activities increasingly drive purchase decisions. The findings provide new insights into the factors influencing purchase intention, thereby enriching the existing literature on consumer purchase behavior in the context of psychological factors. This paper uniquely positions the intention to purchase electric vehicles as a result of autonomy, competence, and relatedness, contrasting with traditional research. The results indicate that psychological factors positively impact innovative consumption, which in turn mediates the relationship between these factors and purchase intention. By employing Partial Least Squares Structural Equation Modeling (PLS-SEM) and Necessary Condition Analysis (NCA), the study examines both direct and indirect effects of psychological factors on purchase intention. It also considers the moderating role of driving experience in the relationship between psychological factors and innovative consumption. This combined data analysis approach provides a comprehensive understanding of the mechanisms influencing purchase intention, highlighting the intricate interplay between psychological determinants and consumer behavior in the adoption of electric vehicles.
