This book is about China’s economy transformation. Currently, China’s macro-leverage ratio has been effectively controlled, the central market interest rate (one year fixed interest rate) has gone down, and liquidity is now relatively abundant. However, financial institutions are generally reluctant to lend, the local governments are unwilling to act, and the fact that liquidity released by the central bank cannot be effectively transmitted to the real economy is leading to a contraction of credit and higher financing costs for private enterprises. Meanwhile, the downturn in the internal economic cycle has been exacerbated by the external shocks caused by frictions in Sino-US trade, and this set of circumstances has contributed to the polarization of expectations regarding China's real economic prospects and policy trends, as seen, for example, in the questions and discussions about policy trends relevant to the private economy. Indeed, one might claim that the current confusion of expectations even exceeds that of 2008, when the international financial crisis breaks out. From a dialectical perspective, the more pessimistic expectation of economic trend, the easier it is to build consensus on reform, and the more remarkable actual effects of reform, which must be based on a comprehensive understanding of the phased characteristics of China’s economic development.
