Abstract

Abstract: The co-citation measure of bibliometrics is employed into a patent analysis to study and show the technological frontier transferring in the digit information communication field of China. Spring embedding algorithm is used to cluster and visualize the patents. The patent maps show that in recent years, the technology hot point is transferring from information encrypt to information distribution and wireless communication. Virtual reality technology, interaction of men and machine, and network technology has been broadly used in this field. The technology frontier tends to become multi-hot points.
