The rapid development of the automobile industry brings substantial environmental challenges to China. Therefore, integrated development strategies targeting both the automobile industry and emission control, although difficult, are essential. Based on a localized model, this paper analyzes the characteristics of and historical trends in China's vehicle emissions and quantifies future trends under various emission control scenarios. The research summarizes and combs the bottlenecks and main contradictions in the process of synergetic development of China's future automobile industry and environmental improvement, puts forward the roadmap for the synergetic development applicable to China, and gives corresponding development proposals and control strategies.
