Research on the Evolution Mechanism of Supply and Demand Network of API Industry Interconnection Based on Improved BBV Model

API industry interconnection supply and demand network is a new model of deep integration of Internet technology and API industry under the background of digital economy era.In view of the limitations of BBV model in describing the evolution process of supply and demand network of API industrial interconnection, an evolution model of supply and demand network of API industrial interconnection based on the improved BBV model was constructed by taking node strength, resource matching degree and technological innovation as the preferred connection indexes on the basis of analyzing the network structure and evolution law.Through the simulation of the dynamic evolution process of the network, the following conclusions were drawn: the degree distribution of the supply and demand network of API industry interconnection approximately conforms to the power law distribution and has the small-world characteristics, and the relevant parameters of the model have certain influence on the degree distribution.The research provides a theoretical basis for API upstream and downstream enterprises to construct industrial interconnection supply and demand network in real life, and has certain reference value for protecting key enterprise nodes, stabilizing supply and demand relationship, preventing sudden failure risk and detecting risk propagation path in reality.
