The Impact of Housing Speculation and Policy Regulation on House Price Fluctuations:Basedon Data from 40 Key Cities in China
This paper constructs a dynamic system model of housing demand structure,policy regulation,and prices,based on quarterly data from 40 key cities from 2007 to 2021,to consider the effectiveness of policy regulation on housing speculation and price fluctuations.The results show that housing speculation has significantly driven up housing prices,and there are significant differences in the impact of government housing regulation policies on housing price fluctuations.Heterogeneity analysis shows that there are differences in the implementation effects of policy regulation in different regions.In view of this,policies should be implemented and classified guidance should be provided according to the situation of a city,while actively unblocking the transmission mechanism of real estate regulation policies,improving transmission efficiency,and promoting the stable and healthy development of the real estate market.
