The fast growth of China's economy has brought it not only to the center of the global economy but also to a transition point in its growth model, a transition from scale to efficiency, speed to sustainability, input driven to innovation led. How its financial markets can drive this new growth model and facilitate the transition are pressing challenges, for China and for the world. We provide a comprehensive review of China's financial markets, including government bonds, corporate/credit bonds, stocks, asset-backed securities, financial derivatives, investment management, and currency, focusing on their growth paths, distinct characteristics, and unique opportunities. Despite fast expansion at times, their development is often lagging behind market needs, uneven over time, and unbalanced across markets. This developmental pattern is driven mostly by the government's immediate policy objectives rather than by the markets' ultimate efficiency in serving their key functions, including liquidity provision, price discovery, and risk allocation. Expected final online publication date for the Annual Review of Financial Economics, Volume 13 is November 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
