<![CDATA[Electric vehicle (EV) adoption in emerging economies is shaped by interacting technical, economic, institutional, and behavioral factors. In Indonesia, despite substantial fiscal and non-fiscal incentives, EV adoption remains below 1% of vehicle sales, reflecting persistent misalignment among government targets, industry capabilities, and consumer acceptance. Existing studies tend to analyze these challenges in isolation and rarely integrate behavioral and institutional dimensions within a single coherent framework suited to such "wicked" policy problems. This study is conceptual and methodological in nature. Through a systematic literature review (SLR) of 81 articles, supported by a System of Systems Methodologies (SOSM) analysis and refined by a pilot workshop with Indonesian experts, it develops an integrated problem-structuring framework. The review indicates that Problem Structuring Methods, particularly Soft Systems Methodology (SSM), remain underutilized in emerging-economy transport policy. On this basis, the study proposes a six-stage integration protocol that positions SSM as the methodological backbone, complemented by Innovation Diffusion Theory (IDT), Principal-Agent Theory (PAT), and Strategic Choice Approach (SCA), spanning problem exploration, innovation analysis, incentive mapping, conceptual modeling, uncertainty management, and implementation strategy. The framework offers a structured way to combine interpretive, behavioral, institutional, and strategic perspectives while maintaining theoretical coherence. Its applicability is illustrated through an exploratory application to Indonesia's EV charging-infrastructure policy, with broader empirical validation identified as a priority for future research.]]>
