阶梯定价的广泛实施，使居民预算约束边界非线性和样本选择时出现即时性，给需求分析带来难题。本文按照逻辑演化过程梳理国外阶梯定价纷争和成果。首先简要整理了阶梯定价下的需求价格设定及其普适性文献，以及所致的需求估计偏误问题。通过简评简化估计、工具变量和极大似然法的不足，指出最新发展须基于微观行为分析和微观数据。其次梳理了多元化目标诉求和现有阶梯定价政策的综合绩效评定对阶梯定价结构类型选择的影响，从而衍生出进一步内生化研究的方向就是确定阶梯定价机制结构参数。
階梯定價的廣汎實施，使居民預算約束邊界非線性和樣本選擇時齣現即時性，給需求分析帶來難題。本文按照邏輯縯化過程梳理國外階梯定價紛爭和成果。首先簡要整理瞭階梯定價下的需求價格設定及其普適性文獻，以及所緻的需求估計偏誤問題。通過簡評簡化估計、工具變量和極大似然法的不足，指齣最新髮展鬚基于微觀行為分析和微觀數據。其次梳理瞭多元化目標訴求和現有階梯定價政策的綜閤績效評定對階梯定價結構類型選擇的影響，從而衍生齣進一步內生化研究的方嚮就是確定階梯定價機製結構參數。

The use of block pricing policy leads to nonlinearity of budget set frontier and co - determinacy in sample selection, further bringing about difficulty in demand analysis. Even Taylor - Nordin specification and its universality under block tariff gradually are recognized, yet it tends to let demand direct estimation biased. In view of RF, IV and SML methods＇ shortcomings in this setting, behavior analysis and micro data are fundamental in new developments. The choice of types of block tariff schedules may be dependent on plural - goal appeals of regulator, and assessments of comprehensive performance on the current block tariff. And the parameterization of block pricing structure will be further researched in the endogeneity literature.
