Abstract

Against the backdrop of China’s dual-carbon strategy, Dalian is actively promoting the development of its new energy vehicle (NEV) industry as a strategic initiative to drive regional industrial upgrading and sustainable growth. This study investigates key challenges impeding the NEV transition, including the slow adaptation of traditional automakers, technical limitations in low-temperature environments, and uneven distribution of charging infrastructure across urban and rural areas. To address these issues, a multi-source data analysis framework was employed, combining time-series forecasting with Latent Dirichlet Allocation topic modeling to capture evolving market trends, consumer preferences, and regional demand patterns. The results highlight a critical need for technological solutions tailored to cold climates, more efficient and accessible charging networks, and enhanced support for emerging NEV brands. Based on these findings, the study proposes targeted strategies for technological innovation, brand development, and infrastructure optimization, offering actionable, data-driven guidance for policymakers and enterprises seeking to accelerate NEV adoption and facilitate sustainable industrial transformation in Northeast China’s traditional automotive hubs.
