To trade off high energy consumption for high GDP growth making both energy consumption and environment pollution of the developing China top in the world is an undisputed fact. The 11th Five-Year Plan has stipulated 20% decrease of specific energy consumption in this period as a restrictive index, this has been gradually detailed and practiced into every link. To compile the thesis of "How to Realize the Target of Energy Consumption 20% Decreased in the 11th Five Year period," this Journal invited Mr. Fang Weizhong, the president of China Macro-Economic Association to contribute a paper entitled "The Severe Energy and Environment Situation in China," in which reasons of failed target of energy consumption in the 10th Five Year period and how to realize energy consumption index in the 11th Five Year period are precisely calculated and in-depth analyzed with detail and practical data. 展开更多

GDP growth of 10.5% in 2006 can't be admired without analysis.The growth of 2.5 percentage points beyond the state's plan was achieved on the costs that energy consumption remained at a high increase rate of 11% and the total discharge amount of main pollutants increased but decreased.To balance out the gain against the loss,the gain is unlikely to outweigh the loss. 展开更多
