From organizations' view, the paper analyzed researcher unique identifier's application progress from three perspectives: implementation status, implementation modes and service mode. The outcome shows that currently researcher unique identifier's implementation has made significant success, however, the following problems still exist: the extent of application needs to be improved, interoperability of different systems is not ideal and the implementation lacks of consistency. In order to solve these problems, the paper gave corresponding suggestions: the promotion of researcher unique identifier's application should be stronger, coordination between different systems should be strengthened and comprehensive method should be adopted to improve interoperability, and systematic mechanism should be made to encourage researchers to update their information.
