Basically, the contents of this paper are organized as follows: Firstly, it is interpreted that the technical identifications of higher education and economic growth and the relative theories such as human capital and new economic growth, which can make theatric basis for the further empirical study. After that, the paper is to construct a couple of index systems to depict higher education development and economic growth respectively. At the end of this paper, it will adopt the dynamic econometric models such as Granger causality test, co-integration test, VAR and VECM model, to evaluate the co-relations between the two systems. According to the empirical study, the paper comes to the conclusions as follows:(1) There really exists one-way causality between the economic growth and the higher education, i.e.
