First, we consider galaxy formation from the viewpoint of hierarchical clustering theory and discuss the possibility that inhomogeneous models with a local void may be compatible with the observed homogeneity of galactic distributions found in recent redshift surveys, because their inhomogeneity can be weakened by the difference in the feedback system of galaxy formation between the inner and outer regions. Next, it is shown with the results of numerical simulations that the observed inhomogeneity of two-point correlations of galaxies can be accounted for by these models. Also, the natural appearance of bulk flows for an off-central observer is demonstrated. Finally, the inhomogeneity of the baryon content is discussed from the viewpoint of our inhomogeneous models.
