Is there a housing bubble in China?

This paper aims to conduct a series of bubble diagnostic analysis over 35 representative Chinese cities. We apply the Log-Periodic-Power-Law-Singularity (LPPLS) model to detect whether there is any evidence of unsustainable, self-reinforcing speculative behaviours amongst the price series. We also investigate whether the prices had been significantly deviating from economic fundamentals by applying the E-G cointegration test. Overall, we found that 10 out of the 35 cities being examined had exhibited positive LPPLS signals. We propose that it is vital to conduct bubble diagnostic tests and implement relevant policies toward specific bubble characteristics.
