Abstract As the strategy of corporates and external environment change, the interfirms R&D cooperation network shows dynamic changes. In this paper, we take Google as an example to construct the twomode network including Agent x Agent network and Agent x Task network by using the Internet information in the Factiva database. We use Dynamic Network Analysis to analysis the R&D cooperation network including structure characteristics and content characteristics. The empirical results indicate that in terms of network structure characteristics, the evolution of the R&D cooperation network of Google shows obvious stage characteristics, the network size is expanding and the network connection is increasing. In terms of network content characteristics, the cooperation content is based on its technological innovation advantages. Some R&D cooperation also begins to focus on a number of different enterprises of different industries, which shows a multiindustry R&D cooperation model. Besides, Google increasingly dependents on senior enterprise and gradually tends to select startup enterprises as its partners. The evolution of R&D cooperation network of Google not only embodies the development principles and strategies of Google but also provides a reference for companies that have their own technological advantages when choosing R&D partners.
