China has achieved hyper economic growth in the past three decades. The achievement, though spectacular, is nothing incomprehensible to modern economic theories. A number of characteristic factors, short-term or long-term, have been favorable to fast growth. The market-oriented reforms that started thirty years ago have installed the preconditions for the economy to benefit from these factors. As China rises to the rank of middle-income countries, some conditions that used to support fast economic growth are now undergoing profound changes. These changes have important implications on capital formation and productivity growth, the two major drivers of growth. With the era of hyper economic growth coming to its end, the growth pattern of the Chinese economy is in transition. That calls for a transformation of government’s role in the economy to answer the challenges of this transition.
