摘　　要：针对电信服务定价中拉姆斯定价存在涨价非均衡问题可进行帕累托改进,但消费者收入来源的不均等,使其对电信服务产品的涨价,存在承受能力的差异。为此,从时间效用的新角度考虑电信服务定价方法,引入时间效用损失来均衡消费者之间的差异性;推导出基于时间效用的拉姆斯定价模型,从而达到消除拉姆斯定价中的涨价非均衡现象。分析结果表明,在高峰定价、最高限价、差别定价的消费者之间和企业与消费者之间都存在定价非均衡现象,基于时间效用的拉姆斯定价可以解决涨价非均衡问题,是拉姆斯定价的帕累托改进。The study is going to make Pareto improvement aiming at the disequilibrium price increase existed in Ramsey pricing, which is usually used in telecom services pricing. But differences in the consumers＇ income lead to have differences in enduring ability to telecom services markup. Therefore, the study takes telecom services pricing into account from the new angle of the time utility. The analysis suggests that introducing time utility loss to balance among customers can set up a Ramsey pricing model on time utility, which can change the disequilibrium price increase situations existed in Ramsey pricing. The result of the analysis indicates that there existed disequilibrium pricing situations using peak load pricing, price-cap pricing and discriminative pricing among consumers and between the enterprises and consumers. Ramsey pricing on time utility can solve the problem of the disequilibrium price increase, which makes Pareto improvement on Ramsey pricing.
