The "Shanghai-Hong Kong Stock Connect", or Hu-Gang Tong, has helped Chinese capital market to draw global attention and will form a pattern that the world capital flows to China in the future. ANBOUND research team believes that the relatively bleak picture of Hu-Gang Tong is due to multiple reasons, among which the asymmetric system frame is an important factor that makes it hard for foreign capital to enter Chinese capital market, especially because capital account liberalization is still cautious. In the future, China should accelerate its reforms in the aspects of opening up the financial market, RMB internationalization and capital account liberalization, etc. to release the huge potential of Chinese capital market.
