Abstract
Clique problem has been fully researched in the social relations network of sociology，But the cliques in inter-enterprise networks have attracted people's attention in recent years. Based on the alliance data of the high-end equipment manufacturing industry in China in 2000-2013, we construct innovation network，and use negative binomial regression models to analyze the impact of the clique structure on enterprise innovation. The results show that the more the clique numbers in the alliance innovation network, the stronger the enterprise innovation capability. Whether the enterprises listed have a negative moderating effect on the impact of clique numbers on enterprise innovation performance. That is, for the listed enterprises, more clique numbers cannot significantly promote enterprise innovation, but for non-listed enterprises, more clique numbers are conducive to enterprise innovation. Innovation accumulation has no significant positive moderating effect on the impact of clique numbers on enterprise innovation performance. The impact of the coreness values on the enterprise innovative output in an inverted-U curvilinear way, and the coreness values also moderates the effect of innovation accumulation on enterprise innovation capability in an inverted-U curvilinear way. The conclusions of the research can provide the basis for the enterprise to embed the network cliques and for the relevant government departments to formulate the alliance policy.
Highlights
Innovation has become an important way for enterprises to obtain the advantage of development
Enterprise embed in the alliance innovation network, from the establishment, cooperation and development to the application of innovative achievements in the form of patent and approval, often takes 2 years or even longer, in order to study the robustness of the results, this study considered the cliques number of alliance, enterprise core degree and the influence of related variable on the innovation performance of 2 years lag to build the models such as table 2
From model 1, it can be seen that the innovation accumulation of the enterprise itself has a significant positive impact on its innovation performance after its embedding of the alliance innovation network
Summary
Innovation has become an important way for enterprises to obtain the advantage of development. The formation and development of alliance innovation network has become the main way of enterprise innovation (Zheng Zhun, Yu Yajun, Wang Guoshun, 2012). This kind of network has a significant structure of core-edge We explore the moderating effects of whether the enterprise is listed as well as their own innovation accumulation Based on these conclusions, we put forward some policy suggestions for the enterprise to embed the network cliques and for the relevant government departments to formulate the alliance policy
