房价一直以来是国家宏观调控的重点,而一线城市的房价更是调控的重中之重。本文选用北上广深四个一线城市从2010年6月到2015年5月的“百城价格指数”建立VAR模型,并通过脉冲响应图以及Granger因果关系检验,表明对于全国房地产市场的调控,短期应该关注广州和上海,长期需注意北京和深圳,从而地方政府在制定房地产政策时应当有所协调。 Housing prices has always been the focus of national macro-control, while the price of first-tier cities is the most important regulation and control. In this paper, the VAR model is established by using the “100 cities price index” from June 2010 to May 2015 in four first-line cities in the north, the south and the south and the impulse response graph and the Granger causality test to prove that the regulation of the real estate market , Short-term attention should be paid to Guangzhou and Shanghai, long-term attention should be paid to Beijing and Shenzhen, so that local governments should formulate real estate policies should be coordinated.
