Financial bubbles in China's stock market were studied using a new method to detect and date collapsing bubbles in real time. The study found 8 bubbles in the Main-Board Market, 6 in the Small and Medium Enterprises Board, and 4 in the Growth Enterprise Market. These bubbles were driven by liquidity and loose credit cycles, except for those in 2014-2015. The frequent appearance of bubbles suggests China's stock market is still developing, with a herd effect and a lack of bubble risk monitoring. This research provides valuable insights for investors, listed companies, and regulatory authorities.
