Abstract:     At present, the core competitiveness of many enterprises is generally low, and the ability of independent innovation and independent learning is relatively lacking. At the same time, in the process of improving the core competitiveness of enterprises, there is not enough attention to knowledge and knowledge management, which has become a bottleneck restricting the improvement of the core competitiveness of Chinese enterprises. Studies have found that knowledge has gradually replaced capital and energy as an important resource for enterprise development, and it is also the key for enterprises to gain a competitive advantage in fierce market competition. With the application of Internet technologies such as big data and cloud computing and the development of "consumer sovereignty", customers have transformed from passive value recipients to value leaders to participate in the value creation activities of enterprises. Therefore, this article intends to analyze the influence mechanism of customer participation on enterprise knowledge innovation from the perspective of customer-enterprise interaction and knowledge sharing.
     A super-network model of customer participation in knowledge sharing that includes three parts: knowledge sub-network, customer sub-network and enterprise organization sub-network is constructed in this article, which describes the relationship among the three heterogeneous nodes of knowledge node, customer node, and enterprise employee node, and the relationship between the homogeneous nodes. At the same time, the article analyzes the process of customer participation in knowledge sharing from four stages: preparation phase, implementation phase, integration phase, innovation phase, and maintenance phase, and builds a process diagram of customer participation in knowledge sharing on this basis. The article adopts the simulation experiment method to study the process model of customer participation in knowledge sharing, and mainly uses Netlogo software to model and simulate the super-network model of customer participation in knowledge sharing. The focus of the article is to analyze the influence of customer knowledge sharing ability, knowledge innovation ability and customer loyalty on the process of enterprise knowledge innovation, and the main conclusions obtained are as follows:
    Firstly, sharing ability, innovation ability and customer loyalty all have a significant positive impact on the process of enterprise knowledge innovation, and innovation ability is the key driving factor to accelerate the process of enterprise knowledge innovation. Compared with the improvement of sharing ability and customer loyalty, the improvement of knowledge innovation ability has a more significant impact on the process of knowledge innovation.
    Secondly, sharing ability is a key factor that determines the total amount of system knowledge. From the experimental data, it can be seen that the improvement of knowledge innovation ability, knowledge sharing ability and customer loyalty can accelerate the process of enterprise knowledge innovation, but compared with the improvement of innovation ability and customer loyalty, the improvement of sharing ability significantly increases the total knowledge of the system. This result shows that the improvement of sharing ability enables knowledge sharing participants to increase their ability to express, transfer and absorb knowledge, further increase the total amount of shared knowledge and improve the efficiency of knowledge sharing, thereby increasing the amount of knowledge in the system.
    Thirdly, the improvement of customer loyalty has an indirect role in promoting sharing ability and innovation ability. The improvement of customer loyalty increases the number of new knowledge nodes and new customer nodes, and accelerates the generation of new knowledge nodes and new customer nodes. This result shows that the improvement of customer loyalty will make customers invest more time and energy in the process of knowledge sharing, and indirectly improve their knowledge sharing ability and innovation ability.
