关于公交票价与私家车出行关系的研究方法

Study Method Concerning Relationship between Bus Ticket Price and Private Car Trip Volume

该文针对研究城市公交票价与私家车出行量之间关系的需要,提出了一种理论方法。该方法用多元线性回归模型分析了城镇居民家庭人均可支配收入、私家车出行成本等因素对私家车出行需求的影响,并在此基础上结合交叉弹性理论进一步得到公交票价和私家车出行需求之间的弹性关系。通过该方法可以量化公交票价与私家车出行需求两者之间的关系,为城市采用低价公交来制约私家车出行的政策提供一些理论依据。

For studying the demand of the relationship between urban bus ticket price and private car trip volume,this paper puts forward a theoretical method.This method analyzes the influence of the per capita disposable income of urban residents and trip cost of private cars on the trip demand of private car by the multi-unit linear regression model.And on this basis to combine the across elastic theory,the paper gives the elastic relation of bus ticket price and private car trip volume.This method can quantify the relationship between the bus ticket price and private car trip demand able to provide some theoretical basis for the policy of the low ticket-price bus to restrict the private car trip volumes in a city.
