Abstract:The formation and development of the blockchain industry ecosystem is a complex and implicit law process, and exploring the law of its evolution is of great significance to promoting the coordinated development of various participants in the system. Based on the value co-creation perspective, construct a symbiotic evolution model of the blockchain industry ecosystem, and analyze the equilibrium point of the model and its stability conditions. Through the computer simulation of different symbiosis evolution modes, the law of symbiosis evolution of the blockchain industry ecosystem is revealed. Research shows: (1) The blockchain industry ecosystem is a complex system that consists of three types of value entities: value center layer, value integration layer, and value service layer, in a certain symbiotic environment, which revolves around value acquisition and innovation interaction to create value together; (2) The degree of symbiosis among the three types of value subjects determines the stability and equilibrium state of the symbiosis evolution of the blockchain industry ecosystem; (3) Mutually beneficial symbiosis is the best direction for the evolution of the value subjects of the blockchain industry ecosystem. System members should strive to transform the parasitic symbiosis and partial benefit symbiosis model to a mutually beneficial symbiosis model.
