Abstract: The international economic environment is complex and volatile, and the global industrial chain and supply chain are adjusting at an accelerating pace. From the research perspective of new development in the new era, the characteristics of the modernization level of industrial chain and supply chain are defined as follows: “two-chain” integration of new economy and new drivers driven by scientific and technological cooperation, “two-chain” integration of new cycle and new iteration driven by interest cooperation, and “two-chain” integration of new manufacturing and new services driven by market cooperation. Based on the BP-SVM joint optimization model, the level evaluation of the collaborative drive industry chain and supply chain network is studied, and the evaluation index system is established. The numerical example is taken to verify the unique advantages of the model. It is found that the risk of game behavior on the network of the industrial chain and supply chain driven by the synergism can be measured by the entropy value, and the comprehensive benefits created by the synergism driven by the modernization system of the whole industrial chain and supply chain can be greatly improved. It further puts forward the formation mechanism and policy suggestions to promote the modernization level of industrial chain and supply chain. The research shows that: growth mechanism construction is conducive to improving the important driving force and endogenous driving force of economic and industrial structure adjustment, choice mechanism construction is conducive to establishing the main means and important direction of enterprise transformation, iteration and upgrading, and constraint mechanism construction is conducive to strengthening the service improvement and management innovation of industrial chain and supply chain governance. The research of this paper provides a valuable new Angle for understanding the internal mechanism of upgrading the modernization level of industrial chain and supply chain.
