佩尔兹曼模型的一个三维拓展及应用——以出租车行业为例

A Three-Dimensional Form and Its Application of Peltzman Model——Illustrated by the Case of Taxi Industry

国内学者鲜有运用佩尔兹曼模型对行业规制问题进行研究,对佩尔兹曼模型本身的探讨也为数不多。以经典佩尔兹曼模型理论为切入点,对其进行推广,拓展模型至三维形式,该形式可以解释公司制出租车行业规制模式,而这种规制模式无法借助于传统佩尔兹曼模型进行分析。研究发现出租车公司容易对规制机构产生影响,从而使规制有利于自身,这解释了近年来出租车行业"份钱"不断增长的现象;将规制模式由公司制转变为个人制,有利于增加社会福利。

There are few scholars studying industry regulations by utilizing Peltzman Model, which is the same as the discussions about the model itself. With Peltzman Model Theory as the entry point, we develop the model into three - dimensional form, describing the Control Mode of taxi industry, which the traditional Peltzman Model is unable to describe. By detailed researches, we conclude that taxi companies are inclined to affect the regulator, so that the regulations usually benefit the companies. That is why the rent of taxi keeps increasing in recent years. Converting Company Mode into Personal Mode will definitely improve the society welfare.
