In order to meet the requirement of separating power plants from power network and that of the competition based power transaction in power market, the pricing decision support system for generation companies (GCPDSS)...In order to meet the requirement of separating power plants from power network and that of the competition based power transaction in power market, the pricing decision support system for generation companies (GCPDSS) is built in electricity market. This paper introduces the conception of intelligent decision support system (IDSS) and puts emphasis on the systematical structural framework, work process, design principal, and fundamental function of GCPDSS. The system has the module to analyze the cost, to forecast the demand of power, to construct the pricing strategies, to manage the pricing risk, and to dispatch giving the pricing strategies. The case study illustrates that the friendly window-based user interface of the system enables the user to take full advantage of the capabilities of the system in order to make effective real-time decisions.展开更多

The result indicates that China's product-specific amber box support level has significantly increased but not yet exceeded the tolerable ceiling of de minimis and remains consistent with WTO rules on agricultural domestic support," that there is still policy room for product-specific amber box support but the ceiling of de minimis has already imposed substantial constraint on China's grain price support policies; and that despite rapid increases in non-product-specific amber box support levels, future policy space remains significant. The result also suggests that China should make appropriate adjustments to product-specific amber box support policies in accordance with WTO rules on agricultural domestic support and make proper use of non- product-specific amber box support policies.展开更多
