Abstract:Propose a framework and method for identifying and selecting R&D partners based on the con-centric diversification of enterprise technology. Starting from the existing technological capabilities, R&D resources and development needs of the enterprise, it can customize the developmental technology direction and identify the best partners for collaborative research and development. First, use association rules to mine the concentric and diversified technical fields of the target company, then use LDA topic modeling to conduct text mining on the patent content of candidate partners and divide them into different technical topics, Finally, a patent evaluation system including profes-sional capabilities and cooperation capabilities is constructed to evaluate candidate R&D partners to determine the best R&D partners under each technology theme. Further empirical analysis with Tasly Group as the target company shows that the above framework and methods are applicable and effective.
