【摘要】：本文通過求解階梯定價下福利損失與再分配效應(yīng)的充分統(tǒng)計量,構(gòu)建評估與優(yōu)化階梯定價的半結(jié)構(gòu)式充分統(tǒng)計量模型。利用從國家電網(wǎng)隨機(jī)抽取的2003—2011年杭州市5000戶居民的月度電量消費(fèi)數(shù)據(jù),評估樣本期內(nèi)實(shí)施與調(diào)整階梯定價的政策效果;在此基礎(chǔ)上對最優(yōu)階梯定價機(jī)制進(jìn)行優(yōu)化設(shè)計,進(jìn)一步評價了杭州市2012年最新階梯定價調(diào)整政策。研究發(fā)現(xiàn):(1)2004年與2006年杭州市實(shí)施與調(diào)整階梯定價的福利損失分配效應(yīng)轉(zhuǎn)化率逐步上升,階梯定價再分配的邊際福利損失與初次分配的稅收邊際福利損失相當(dāng);(2)分時階梯定價分配效應(yīng)轉(zhuǎn)化率比純階梯定價低,嵌入分時定價的階梯定價不能有效地實(shí)現(xiàn)階梯定價目標(biāo);(3)與最優(yōu)階梯定價機(jī)制相比,2012年的最新階梯定價調(diào)整方向正確,但第一階梯長度擴(kuò)展過多、第二階梯擴(kuò)展不足,而階梯加價太小;(4)較之結(jié)構(gòu)與縮減式模型,充分統(tǒng)計量方法極大節(jié)約數(shù)據(jù)信息量并能進(jìn)行福利分析。本文的研究為評估與優(yōu)化我國各類政府公用事業(yè)改革開拓了一條新思路。
[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.
