It aims to bring prosperity through partnership among nine Chinese Mainland provinces and China ＂s two special administrative regions. In this paper, we use a dynamic panel data model to examine the economic growth of the PPRD economies from 1985 to 2009. Our analysis confirms the existence of regional growth spillover effects in the PPRD area. Our results also show that economic growth spillover effects of non-PPRD regions on the PPRD regions are greater than those among the PPRD members themselves. These findings imply that economic integration between Chinese provinces has generated considerable spillover effects on regional growth. However, the anticipated benefits of the implementation of the PPRD agreement have not been realized thus far. Therefore, greater effort shouM be made to promote further economic integration among these members so that their local economies can benefit from the positive spillover effects.展开更多

In this study, we use the National Economic Research Institute （NERI） Index of Marketization and a panel data model to investigate the quantitative contributions of marketization to China＇s total factor productivity （TFP） and economic growth. Our results indicate that marketization contributed 1.45 percentage points on average to China＇s annual economic growth rate during the period from 1997 to 2007 and accounted for 39.2 percent of the increase in TFP. Marketization significantly improved resource allocation. However, economic transition in China has not yet been completed and sustainability of future growth will depend on further market-oriented reforms.展开更多
