In this book, Dr. Jun Zhang rebuts the widely-held view that Chinese economic growth is unsustainable due to low consumption and a reliance on exports and enormous fixed-asset investments. Though many believe this "structural imbalance" of the Chinese economy will become a serious problem in the long run, Zhang holds a bullish long-term outlook owing to China's long-term economic development. For Zhang, China's structural problems are greatly exaggerated and certain structures, such as regional governing entities, ensure that China will not face the same economic issues that Japan encountered. Through regional competition, regional governments will persevere; Zhang predicts that China will overtake the US as a superpower. Zhang concludes by acknowledging the real dangers facing China's economy, and offering advice on the reforms needed to ensure continued growth

In this paper, we introduce the mixed estimators based on product least relative error estimation and least squares estimation in a multiplicative linear regression model. The asymptotic properties for the mixed estimators are established. We present some explicit expressions of the optimal estimator of the mixed estimators, and we also suggest some numerical solutions in the simulation studies and real data analysis. Studying model checking problems for multiplicative linear regression models, we propose four test statistics. One is the score‐type test statistic, the second one is the residual‐based empirical process test statistic marked by proper functions of the covariates. The third one is the integrated conditional moment test statistic by using linear projection weighting function, and the fourth one is the adaptive model test statistic. These test statistics are all related to the mixed estimators. The asymptotic properties of these test statistics are established, and some bootstrap procedures for calculating the critical values are also proposed. Simulation studies are conducted to demonstrate the performance of the proposed estimation procedures, and a real example is analyzed to illustrate its practical usage.
