DICP was established with the name of Scientific Research Institute of Dalian University on March 19, 1949, which is even a little earlier than the foundation of the People's Republic of China (October 1, 1949). Since then, the name of the institute has changed several times in order to fulfill the assigned regional and national research mission.
