Under economic globalization circumstance, the increasing competitiveness of industry cluster has been becoming powerful driving force in the regional economy development. Innovation provides with a source of competitive advantages in industrial cluster, and it is also the key factor of survival and sustainable development in the cluster enterprise as well. However, it needs to point out that closed and temporary innovation could not sustain its long-term competitive advantage, especially under the current complex and dynamic environment. If any enterprise would like to keep up its long-term innovation advantage, it should reach cooperative innovation by getting benefits from external resources under the trend of networking. Even some enterprises have been paying more and more attention on innovation; most of the enterprises do not have thoroughly understanding on innovation and could not realize of the importance of social network in the cluster on innovation. Therefore, it is quite urgent for the cluster enterprise to solve how to establish business relationships on the connection of social network and innovation actor, developing cooperation in a profound and high level way, realizing resources complementation, boosting the spread of information and knowledge, organizing learning, upgrading the innovation capability and core competitiveness in the cluster enterprise. At present, there is less research undertook for cluster enterprise on innovation especially innovation based on social network and less knowledge of social network factors for the influence on innovation capability by cluster enterprise. Hence, its route of increasing the innovation capability for the cluster enterprise has not been found yet, and the directive theories and methods of corresponding innovation practices are indeed needed.First of all, the thesis has arranged a systemic summary of relevant theoretical bases and made an intensive study of characteristics of industry cluster network organization, trust of cluster social network and system of organization learning to lay theoretical bases for the following research. Secondly, to analyze the cluster innovation system by applying its social network analysis approaches. Through the basis of introductions of cluster innovation system, describing the features of cluster innovation system, analyzing the composing elements of the cluster innovation system, connecting mechanism and connecting approaches to fulfill the empirical research. Thirdly, to establish the cluster enterprise innovation mechanism model based on the social network. Combining the social network theories, industrial cluster and technology innovation theories, the thesis analyze the interaction mechanism of cluster enterprise innovation through organizing learning by social network actor and social network relations which concludes the complete theories model based on the above interaction mechanism. Finally, to undertake empirical research based on the theories model. By comprehensively applying social network analysis, structural equation model and multiple regression analysis to analyze the sample data, and verify the theories model, which has further proved the interaction mechanism on cluster enterprise innovation through social network.By conducting the theoretical and empirical research, the thesis has firstly unveiled the interaction mechanism of cluster enterprise innovation based on social network actor and social network relationship. Secondly, there is intermediation function linked by explorative learning and exploitative learning together with social network and cluster innovation. Thirdly, the thesis proves that cluster innovation system is an ope n and complete innovation network. Fourth, it is clearly defined the mediation function could be worked in cluster enterprise under uncertain environment. According to the discussion and analysis of the empirical research, it would have significantly instructive and practical value on the cluster enterprise innovation based on its social network. |
