This paper focuses on the opportunities and challenges faced by the coordinated development of the industrial chain in the Yangtze River Delta under the current new development pattern. We combine policy research, international comparative research, and industrial case studies to analyze the new environment and key industries faced by the industrial economy in the Yangtze River Delta. Then we analyze challenges and opportunities of the industrial chain in the Yangtze River Delta from the perspectives of basic coordination model, industrial structure changing trend, and value flow in the industrial chain. Finally, we put forward policy recommendations for optimizing the industrial division among cities in the Yangtze River Delta in order to give full play to the fulcrum role in the international and domestic dual circulation and promote the coordinated improvement of industrial chain in the Yangtze River Delta.
