The purpose of this paper is to analyse the housing market's equilibrium of demand and supply from housing completion rate and housing vacancy quantity. This paper takes Wuhan as an example. The results indicate that the housing supply are surplus from 1999 to 2003. The housing supply have fallen short of demand from 2004 to 2007. The structure of housing supply was unreasonable between 2005 and 2006. The housing demand and supply will keep in equilibrium under reasonable macro-control policies through the forecast of housing demand and supply from 2008 to 2015. The government should eliminate the non-market factors, increase the housing effective supply, slow down the improvement demand, and suppress the speculative demand to realize housing market equilibrium of demand and supply.
