THE PROMOTING OF POLICY 30@30: (EV 3.5) THAT AFFECTS THE FACTORS OF CONSUMERS' DECISION-MAKING ON PURCHASING ELECTRIC VEHICLES (EVS) IN BANGKOK METROPOLITAN AREA

Abstract

This academic article aims to (1) analyze the second-phase electric vehicle promotion measure (EV 3.5) under the 30@30 policy, and (2) explain the impact of this measure on the factors influencing consumers’ decisions to purchase electric vehicles in Bangkok. The study emphasizes the role of the policy as a key mechanism in driving Thailand toward a low-carbon society and upgrading its modern automotive industry. The article employs document analysis and synthesis of government policy documents, academic reports, and related research. The analytical framework integrates public policy theory and consumer behavior theory to explain the linkage between government measures and the consumer decision-making process. The findings indicate that the EV 3.5 measure plays a significant role in reducing price barriers through financial subsidies and tax incentives. These mechanisms strengthen economic motivation and enhance consumer confidence in adopting electric vehicles. However, several limitations remain, including insufficient charging infrastructure, challenges in managing end-of-life batteries, and the overall societal readiness for technological transition. The article recommends that the government accelerate the expansion of comprehensive charging infrastructure, establish a systematic end-of-life battery management system, and promote public communication to enhance consumer awareness and understanding. These efforts should be accompanied by consistent, clear, and sustainable incentive measures to improve the long-term effectiveness of electric vehicle promotion in Thailand.
