The integrated development of regional higher education is inseparable from the fuel of driving force and dynamic mechanism．Its development dynamic is mainly composed of the internal driving force of the innovation and development paradigm of regional colleges and universities as well as the exogenous driving forces such as the leading force of the government，the propelling force of regional market integration and the bonding force of regional culture. The dynamic mechanism mainly consists of three parts：incentive mechanism，guiding mechanism and constraint mechanism．The dynamic mechanism has the functions of stimulating，guiding，restraining and controlling the direction and strength of the dynamic．At present， the integrated development of higher education in Chengdu and Chongqing economic zone faces unbalanced dynamic structure with irresilient internal driving force and strong but uneven external driving force，which is closely related to the imperfect dynamic mechanism and its weakening functions．Normalizing a sound development of higher education integration in the Chengdu and Chongqing economic zone should focus on enhancing， converging and controlling the internal and external development dynamic， and improving the dynamic mechanism by upgrading the incentive mechanism， guiding mechanism and constraint mechanism．
