Through the empirical survey data of the real estate market, the paper makes a quantitative analysis on the effects of clearing the land value-added tax on the real estate market. The results show that the clearing of land value-added tax raises the level of corporate tax burden. But for the real estate industry, land value-added tax is not high and has few impacts on corporate profits. At the same time, the impacts vary for different types of enterprises. Land value-added tax lowers prices of real estates in the short term, but bids up prices in the long term. China's land value-added tax system still has room for improvement.
