摘要
运用增长率法,建立指数增长的模型,结合规划期的人口规模,预测规划期的居民出行量和居民出行强度,以及乘坐出租车人口,随后利用出租车空载率为主要参数,建立数学模型并预测出租车的最佳数量.利用经济学分析方法,用埃奇沃思盒式图描述交易双方的福利变化,建立均衡时的价格竞争模型,寻求使司机和乘客达到帕累托改进的可能性.分别就油价调整前后的情况,找出调整起租基价和综合单位里程车价能使双方都满意的次优方案.进一步分析了起租基价和里程的合理性,提出了数据采集的建议和方案,并向市公用事业管理部门概括介绍.模型对确定其他类似准公共产品的供应量和定价也具有一定的借鉴意义.
Exponent model was proposed in this paper to forecast the amount and rate for the residents＇ go- ing - out in expected period, and the population of people by taxi, according to the population increasing in future. Based on the ratio of ineffective carrying of taxi, the optimal number of taxies was forecasted by the model. With the method of economic analysis, especially from the Edgeworth Box, competitive model was established to find out the possibility of Pareto Improvement for taxi drivers and passengers. Hypo - optimal solution was determined before and after the adjusting of gas price to satisfy both the drivers and passengers by changing the fixed and alterable price of taxi. Besides, rationality of fixed price and distance was also analyzed, and advice on date collection was proposed to the government. This model can be also expanded to quantity and price determining of other similar public goods.
