In China, aggregate investment levels have been high and the cycles of investment growth rate have been remarkable. In order to reveal the mechanisms which drive investment hunger and cycles, this book develops an integrated growth-cycle framework which integrates the standard theory of socialist economies, the distributive barrier-constrained growth theory of developing economies, and the recent technical progresses in the western business cycle theory. It also analyzes the evolutionary dynamics of China's state investment system and the policy trade-off between industrial expansion and agricultural development.
