The study of quasars clustering could become an important discriminant among different scenarios of the formation of large scale structure. The quasar clustering has now been confirmed and measured (Chu and Fang, 1986; Shaver, 1988) and the evolution of quasar clustering has been reported (Fang, Chu and Zhu, 1985; Chu and Fang, 1986). In the present work a large sample of about 3600 quasars in Hewitt-Burbidge catalog is employed and it is divided into several subsamples with different redshift ranges, a comparison of the correlation function in different subsamples provides then a mean of studying the evolution of the clustering with cosmology time.
