Research on product-competition network based on hyper-network

There are some shortages in using the model of digraphs network, bipartite network, and complex network to study product competition among enterprises. In this paper, by introducing hyper-network model to investigate this problem, we present several lemmas and properties which hyper-network and complex network should satisfy. Finally, we apply these models to solve product competition problems from automobile parts enterprises in China and draw some useful conclusions.
