Abstract
Electric vehicles (EVs) are recognized as effective solutions to the global air pollution problem, attracting much attention from businesses, governments, and consumers. Despite the heightened interest, EV penetration rates remain low. This study thus focuses on consumers’ evaluation of EV innovation to provide implications for promoting EV adoption by proposing a theoretical model that integrates the diffusion of innovations theory and the theory of planned behavior to examine the relationship between consumers’ perceived innovation characteristics and the adoption of EVs; the study findings indicate that the evaluation of consumers’ EV innovation has a significant impact on consumers’ attitudes toward and intention for EV adoption. Several important innovation characteristics promote practical implications for spreading EV acceptance.

The world is facing environmental problems due to global warming and climate change caused by excessive use of fossil fuels
This study proposes a theoretical model integrating theory of planned behavior (TPB) (Ajzen, 1991) and diffusion of innovations (DOI) theory (Rogers, 2003) to examine the relationship between consumers’ evaluation of innovativeness for Electric vehicles (EVs) and the adoption of EVs
This study proposes a DOI–TPB integration model to better determine the adoption of EVs when analyzing the perceived innovation characteristics (PICs) of EVs on the attitude toward and acceptance of EVs
Summary
The world is facing environmental problems due to global warming and climate change caused by excessive use of fossil fuels. In the U.S, >30% of total greenhouse gases are emitted from the transportation sector, of which >60% are emitted by light-duty vehicles (U.S Environmental Protection Agency, 2015). Gasoline-fueled vehicles and existing internal combustion engine vehicles are suggested to be the main culprit of environmental pollution (White & Sintov, 2017). Alternative fuel vehicles (AFVs) have been proposed as promising measures to resolve air pollution-related problems (White & Sintov, 2017); among AFVs, the electric vehicle (EV) does not use fuel, operates a motor through batteries, and generates minimal exhaust gas, and they are attracting attention with respect to solving the greenhouse gas-related problems. Several countries have initiated policies to stimulate the production and acceptance of EVs and reduce CO2 emissions to meet their sustainability goals (Brady & O’Mahony, 2011; Rezvani et al, 2015)
