On the basis of a decaying-particle cosmological model with a massive decay product whose present Jeans wavelength is ~ 30 h(-1) Mpc (the Hubble constant H0 = 100 h km s(-1) Mpc(-1) ), we study the correlation functions and velocity distributions of galaxies and clusters of galaxies using the direct method of N body simulation for these objects and the simple difference method for the dark matter fluid consisting of the decay product. It is assumed that the power index Ns of the power spectrum of the initial density perturbations is 0, -1 and -2, the redshift zd corresponding to the decay time is 2 ~ 3 and the present density parameter Omegad0 for the decay product is 0.8 ~ 0.9. The dark matter fluid prevents galaxies from clustering in the small-scale and helps clusters of galaxies clustering in the large-scale. Owing to this role of the dark matter fluid, models in the case Ns = 0 ~ -1, Omegad0 = 0.8 ~ 0.9 and zd = 2.0 ~ 3.0 are found to be consistent with the observational results on the correlation functions and velocity distributions.
