China is trying to ensure the stability of the supply chain of the industrial chain. How to decompose the industrial chain and the supply chain to do research on its stability At present, most of the stability of the industrial chain is the government's policy help to break through the blocked chain. But what kind of industrial chain is stable, how to establish the index system for evaluating the stability of the industrial chain, can we use the risk management as a reference for index establishment. Are there other factors such as cooperation, industrial development prospects, resource policy support, Technical bottlenecks, etc. My idea is not mature, I hope to get your suggestions.
