In the process of China's rapid economic growth, Chinese Communist Party implemented a series of macro-economic policies --- fiscal policies and monetary policies --- to regulate its economy. As a result, it safely passed through the Asian financial crisis in 1997 and the world financial tsunami in 2008, and was able to continue steady growth. This dissertation focuses, under the Chinese Communist economic system, on how to apply the macro policy to control its growth and what has been the practical impact. What role is macro-control playing in the process of China's economic development? Macro-economic policy is actually the main driving force behind China's economic performance. This dissertation emphasizes that under China's unique political economy, macro-control leads China's rapid economic growth. Nevertheless, due to China's economic structure of market imperfections, and the lack of inherent stability of the market mechanism, the Chinese macroeconomic regulation and control has easily lead to economic volatility and to a possible hard crash in years ahead. Although the experience accumulated so far has led to a relatively stable economy, the economic structure is still incomplete. This dissertation argues that China's macro-control¡¦s aggregate demand in driving China's economy needs to be adjusted from investment and export to personal consumption in order to contribute to sustainable economic development in the future.
