【摘要】：本文通过求解阶梯定价下福利损失与再分配效应的充分统计量,构建评估与优化阶梯定价的半结构式充分统计量模型。利用从国家电网随机抽取的2003—2011年杭州市5000户居民的月度电量消费数据,评估样本期内实施与调整阶梯定价的政策效果;在此基础上对最优阶梯定价机制进行优化设计,进一步评价了杭州市2012年最新阶梯定价调整政策。研究发现:(1)2004年与2006年杭州市实施与调整阶梯定价的福利损失分配效应转化率逐步上升,阶梯定价再分配的边际福利损失与初次分配的税收边际福利损失相当;(2)分时阶梯定价分配效应转化率比纯阶梯定价低,嵌入分时定价的阶梯定价不能有效地实现阶梯定价目标;(3)与最优阶梯定价机制相比,2012年的最新阶梯定价调整方向正确,但第一阶梯长度扩展过多、第二阶梯扩展不足,而阶梯加价太小;(4)较之结构与缩减式模型,充分统计量方法极大节约数据信息量并能进行福利分析。本文的研究为评估与优化我国各类政府公用事业改革开拓了一条新思路。
[Abstract]:In this paper, by solving the sufficient statistics of welfare loss and redistribution effect under ladder pricing, a semi-structural sufficient statistic model for evaluating and optimizing ladder pricing is constructed.The monthly electricity consumption data of 5000 households in Hangzhou from 2003 to 2011 were selected randomly from State Grid to evaluate the effect of implementing and adjusting ladder pricing policy in the sample period, on the basis of which the optimal ladder pricing mechanism was optimized and designed.Further evaluation of Hangzhou in 2012 the latest ladder pricing adjustment policy.The study found that the conversion rate of welfare loss distribution effect of implementing and adjusting ladder pricing in Hangzhou City in 2004 and 2006 gradually increased.The marginal welfare loss of step pricing redistribution is equivalent to that of tax marginal welfare loss of initial distribution. The conversion rate of step pricing distribution effect is lower than that of pure step pricing.Compared with the optimal ladder pricing mechanism, the latest step pricing adjustment direction in 2012 is correct, but the first step length expansion is too much, the second step expansion is insufficient.Compared with the structure and the reduced model, the sufficient statistical method greatly saves the data information and can carry on the welfare analysis.The research of this paper opens up a new way to evaluate and optimize the reform of various kinds of government utilities in China.
