In this paper, we give a new method of recognizing real estate early warning indexes system based on the theory of system core and coritivity. According to the dependent degree of indexes, drawn from Gray Correlative Analysis (GCA), we can get the topology graph of real estate system and its core. Then we can recognize the key indexes, which can provide exact information about the development trend of the real estate.
