Abstract
Indonesia’s transition towards electric vehicles (EVs) is progressing alongside the expansion of charging infrastructure, yet purchase decisions may depend on both environmental motivation and perceptions of infrastructure readiness. This study examined the effects of environmental concern and perceived charging infrastructure readiness on EV purchase intention among prospective car buyers in urban areas of Indonesia. A quantitative causal-associative design was applied to data from 536 respondents across eight urban areas. Responses were collected using a five-point Likert-scale questionnaire. The analysis included validity and reliability testing, tests of classical assumptions, multiple linear regression, t-tests, an F-test, and the coefficient of determination. Environmental concern had a positive and significant effect on purchase intention (B = 0.467; t = 14.936; p < 0.001). Perceived charging infrastructure readiness also had a positive and significant effect (B = 0.510; t = 15.854; p < 0.001). Simultaneously, the two variables significantly explained purchase intention (F = 350.404; p < 0.001), accounting for 56.8% of its variation. Within the tested model, perceived charging infrastructure readiness showed a slightly larger standardised beta coefficient than environmental concern. The findings indicate that EV purchase intention among prospective urban car buyers is shaped by both environmental considerations and confidence in the availability, accessibility, speed, and reliability of charging infrastructure.
