Based on the perspective of supply structure, this study investigates the evolution path of start-up platform structure and user scale. The results show that the competitive relationship model is stricter than the reciprocal relationship model in selecting suppliers. In the competitive relationship model, the competitive intensity will bring more threats to the relatively weak side of the platform, while the cross-network externality will bring more large-scale changes to the relatively superior side of the platform. In the reciprocal relationship model, the enhancement of complementarity intensity and the externality of the crossover network are conducive to the expansion of the platform scale. The evolution path of user scale is related to the intensity of externality of cross-network. In the competitive relationship model, low competitive strength is conducive to the expansion of platform synergy scale. and both the scale and growth rate of platform synergy increase with the increase of externality.
