Research on NEV Consumption and Co-Development in Tianjin: Based on the Policy-Technology-Demand Framework and AI-Driven Empirical Analysis

Against the backdrop of global carbon reduction strategies and the rapid development of artificial intelligence, this study focuses on the new energy vehicle market in Tianjin, employing questionnaire surveys, in-depth interviews, and empirical analysis methods. Based on 920 valid questionnaires, the study analyzes consumer behavior. The findings reveal that the middle-aged group (25–35 years old) and the middle-income bracket (annual income of 100,000–200,000 yuan) constitute the main consumer base, with their purchasing decisions significantly influenced by policy subsidies, the availability of charging infrastructure, and range anxiety; New energy vehicle user satisfaction is primarily driven by safety, with charging convenience and after-sales service identified as key areas for improvement. To address issues such as inadequate infrastructure, the study proposes establishing a collaborative mechanism guided by the government, led by enterprises, and involving societal participation; to address the inadequacy of the market service system, it recommends establishing a standardized service system and value protection mechanism to regulate after-sales service and the used vehicle market; To address the disconnect between environmental values and consumer behavior, a guidance system should be established to strengthen environmental education, improve incentive policies, and promote the implementation of corporate environmental technologies; To address the mismatch between technological adoption and user perception, a demand-driven and scenario-based technology R&D and promotion model should be established to clarify technical standards, adjust R&D directions, and enhance technological outreach. The research findings provide theoretical guidance and practical strategies for the development of the regional new energy vehicle market, thereby enhancing the development level of Tianjin's new energy vehicle market
