内容摘要:

China officially initiated 211 Project approved by the State Council in 1995. It was the biggest and most important project that was authorized by China in the higher education since the founding of New China. As a response to the domestic and international situation at the tum of the century, Chinese leaders made the important decision to develop the higher education 211 Project drives the overall development ofparticipating universities through major innovations. It encompasses developing university subjects and teaching faculties, as well as other core elements aimed at improving university standards. The 211 project thereby explores successful ways to develop the high level universities.211 Project has been remarkably successful over the last 17 years. It has improved the overall educational quality of chinese higher level education, scientific research standards, and its institutional management and administration. The project has established the foundation for china to help top ranking universities operate at an advanced global level.
