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
为研究城市轨道交通分时定价的票价方案和公益性水平评价问题,本文从公益性角度出发,考虑票价和客流量的相互作用关系,以各时段的票价率为决策变量,基于交通方式影响因素和乘客出行选择行为,构建以系统乘客总出行时间最小为目标的双层...为研究城市轨道交通分时定价的票价方案和公益性水平评价问题,本文从公益性角度出发,考虑票价和客流量的相互作用关系,以各时段的票价率为决策变量,基于交通方式影响因素和乘客出行选择行为,构建以系统乘客总出行时间最小为目标的双层规划模型;设计基于嵌套Method of Successive Averages的混合多种群遗传算法的求解方法;采用实际数据标定模型中关键参数,分析比较不同分时定价方案的票价率和公益性水平,提出基于公益性的分时定价方案。研究结果表明:在分时定价策略的效果中,能较明显地提升系统城市轨道交通公益性水平的方案为差别定价(高峰和非高峰票价下限和上限相同)和仅非高峰期降价策略,其中,前者的非高峰期和高峰期票价分别为0.1元·人^(-1)·km^(-1)和0.2元·人^(-1)·km^(-1),相对于原票价方案使总广义费用和总出行时间分别降低12.75%和8.23%;较明显地降低公益性水平的方案为仅高峰期升价策略。展开更多
