Abstract:
At first,according to the theory on sharing in the educational cost,two basic differential equation models are present for describing the educational charges of universities under appropriate assumptions.Then,by analyzing the two basic models qualitatively,several conditions are obtained for the universities to preserve and stabilize its charges.Finally,by analyzing several special models of the two basic models for the educational charges of universities in three cases,some new conclusions and suggestions are given for macroscopically adjusting and controlling the educational charges of universities and scale of recruit students.In addition,three extended differential equation models are also proposed.
