Research On Identification Of Technological Trajectory Based On Patent Citation Network -Taking Wind Motors Technology As An Example

Using patents and patent citation network to identify technological trajectory. Elaborate the principle of technological trajectory identification, form the algorithm of it and provide theoretical basis for the feasibility of its identification as well as visualization. Identify and map the technological trajectory combining the wind motors data, elaborate main nodes and explore technology evolution history as well as future trends in order to provide some decision-making reference on the development of related industries in China.
