Abstract:

Based on the analysis of the factors affecting real estate prices from the perspective of supply and demand, this paper constructs a time-varying parameter state space model, and measures and empirically analyzes the housing bubble in Tokyo, Japan and Shanghai, China. The calculation results show that from the 1st quarter of 2004 to the 1st quarter of 2018, the average housing price bubble in Shanghai was 9.38%. 2009-2011 and 2015-2017 were the periods of two rounds of bubbles, with peak foams reaching 18.29% and 18.59%, respectively. Through the impulse response function, the paper analyzes the turning point of Shanghai's housing price bubble. Financial policies are short-term factors affecting the turning point of the housing price bubble. Land supply and real estate development investment are the medium-term factors affecting the turning point of the housing price bubble. The sustainability of income growth and population growth are long-term factors affecting the turning point of the housing price bubble. The bubble measurement method provides a policy reference for governments to judge the housing price bubble. The study of the turning point of housing pricing bubble can provide a concise policy framework for stabilizing housing prices, that is, the financial policy is only the symptom, the land policy and the economic and population policies are the root causes. On the premise of stabilizing finance, through comprehensive policies of land, population and economy, we can ensure that house prices will be stable and far-reaching.
