In reality, many industries consist of different ownership enterprises. That is, state-owned enterprises, private enterprises and foreign enterprises are coexistence; even a single enterprise is mixed-ownership. Besides, innovation becomes more and more complex; many enterprises cooperate in R&D with others. Combining the study on innovation in mixed oligopy and on network formation, the paper addresses following problems:in mixed ownership industries, what structure of R&D network will be formed? Will the network be consistent with the social optimum? How do the policies affect the network structure?On the basis of reviewing the existing literatures, the paper first theoretically answers the questions mentioned above. In the beginning, the formation of R&D network among one state-owned enterprise and two private enterprises without R&D subsidy in closed economy is disscussed. Secondly, foreign enterprise is introduced in the model to analyze the formation of R&D network in mixed oligopoly in an open econmy. Then, the analysis is extended by considering the role of R&D subsidy in closed and open economy respectively. In the end, the paper empirically analyzes the innonative networks of the automobile engine industry and electronic information industry.The main theoretical conclutions are summarized as following:Firstly, the paper studies the network stability and network efficiency in closed economy with R&D subsidy or not. (1) Stability. Without R&D subsidy, complete network is pairwise stable and strong stable. Private-partial network is pairwise stable and strong stable if and only if (3<0.07. With R&D subsidy, only complete network is pairwise stable and strong stable. (2) Efficiency. Without R&D subsidy, within the proper spillover range, complete network, public-hub star, private-hub star, private-partial network, and public-partial network are probably Pareto efficient except empty network. With R&D subsidy, complete network is always Pareto efficient. Private-hub star is Pareto efficient network if and only if P<0.16. Complete network is the only strong efficient network.Secondly, the paper studies the network stability and network efficiency in open economy with R&D subsidy or not. (1) Stability. Regardless of with or without R&D subsidy, only complete network is pairwise stable and strong stable. (2) Efficiency. Without R&D subsidy, within the proper spillover range, complete network, domestic partial network, and public-hub star, domestic private-hub star, foreign private-hub star are probably Pareto efficient. But empty network, private-partial network, public-foreign-partial network are never Pareto efficient. In the all range of spillover, complete network is the only strong efficient network. Complete network is the only network which makes domestic-partial efficiency reconcile with global network efficiency if and only if β≤0.86. With R&D subsidy, complete network, domestic private-hub star, foreign private-hub star are probably Pareto efficient. But other kinds of network are impossibly Pareto efficient. In terms of all degree of spill over, complete network is the only strong efficiency network. At the same time, complete network is the only network which domestic-partial efficiency and global network efficiency is strong consistency.The main conclusions drawing from empirical analysis are as following:At the whole network level, on the one hand, innovative networks are sparse. But on the other hand, networks are characterized by high clustering. State-owned enterprises and private enterprises respectively locate in the core and the periphery of the networks. The collaborations between different ownership enterprises do exist but are inferior to optimality.Innovative networks are denser in high technique industries than in traditional industries, Innovative collabrations between state-owned enterprises and private enterprises are more common in high technique industries than in traditional industries.In developed regions, the clustering coefficient of innovative network is bigger than it is in underdeveloped regions. State-owned enterprises play less important role in developed regions than in underdeveloped regions.
