The evolution of the space two–point correlation function of quasars (CFQ) is studied. It is assumed that quasars as well as other elements of the large scale structure of the Universe are formed in the peaks of the random Gaussian field of scalar density fluctuations with the corresponding scale R. The quasars are supposed to be the short term active processes in the center of such fluctuations and form offer appearance of the first counter flows in collisionless component and shock wave in gas. It is shown that observable decreasing of the amplitude of the CFQ can be explained in the framework of such an approach when quasars are formed in the low peaks of density fluctuations \mbox{$ν(z)\leq1.3$}. In this case the amplitude of the CFQ has the minimum at \mbox{$z_*≈(0.9\div0.8)σ(R)-1$}, ($σ(R)$ — root mean square of density fluctuations) and grows at \mbox{$z>z_*$}. The decreasing of CFQ when $z$ increases at $0
