For a long time, Shanghai University for Science and Technology, Shanghai University for Science and Technology and Shanghai Second Medical University are the backbone of Shanghai's municipal universities and important talent training bases in Shanghai. In the national 2 1 1 project selection in 1990s, local universities in Shanghai won two places. In order to let all three local universities be selected, the Shanghai Municipal Government had planned to merge the University of Shanghai for Science and Technology and rename it Shanghai University of Science and Technology or East China University of Science and Technology, but the above names were preempted by Shanghai Institute of Machinery and East China Institute of Chemical Technology respectively. So for the new school name, it had to be merged into another local university, the former Shanghai University. Due to the strong position of Shanghai University of Technology, the leading group of the new Shanghai University is mainly Shanghai University of Technology. The motto of Shanghai Polytechnic University is self-improvement, and the teaching system completely inherits the style of Shanghai Polytechnic University. Although this is conducive to unified management, it is also crucial to ignore the traditions of other merged schools and cause brain drain after the merger.
