The State Council decided to raise the retail electricity price by 0.25 Yuan/kWh from July, 2008. This will, to some extent, relieve the conflicts between power supply and demand, and decrease the economic losses in

On this basis, the paper conducts a comparison of overall price plan/macro-control objectives and actual implementation results. Based on an in-depth dissection of the deviations between plan objectives and actual results, this article offers specific policy recommendations on how to improve and strengthen macro-control over overall price movement.展开更多

Theoretically, international factors have impact on the domestic general price level through a set of channels. This paper employed a sample including monthly data of five representative indicators, to explore the influence of international factors on Chinese price level. The empirical results showed that there is an obvious lag for Chinese CPI reacting to international shocks, while the PPI reacts immediately. The impact of international factors on Chinese CPI and PPI usually lasts 12 months at least and they always exhibit a different transmission mechanism for international shocks.Besides, a further study revealed that some structure-breakpoints in the influence mechanism of international factors exist, and great changes of the impact direction and significance for different factors have taken place in the subsample periods.展开更多
