摘要
为更好地分析影响快递价格的因素,在分析基于合并式快递运输组织方案的快递作业流程、快递市场竞争中消费者行为、快递企业行为、运输企业行为及其均衡条件的基础上,应用变分不等式方法,建立快递竞争网络均衡模型,并应用修正投影算法进行了求解.算例计算分析表明,快递价格与区域的快递平均质量、运输企业和快递企业的成本以及消费者与快递企业交易成本成正比,与运输市场和快递市场的竞争激烈程度成反比,且快递企业的竞争力随其与消费者交易成本的增加而减弱.
In order to analyze the contributing factors of express-delivery price, the research attempts to evaluate the express-delivery operation procedures based on the union＇s express-delivery organization plan, consumer behaviors, behaviors of related transport enterprises as well as the equilibrium condition in competitive express-delivery market. The paper adopts the variational inequality and builds the express-delivery market competitive network equilibrium model, and uses a modified projection algorithm to solve this model. Case studies demonstrate that express price is proportional to the average weight, the cost of transport and express-delivery enterprises, the exchange cost between consumer and express enterprises, while is disproportional with the competition of transport and express market, and the competitiveness of express-delivery enterprises is weakened with the increasing transaction cost between the consumer and express enterprises.
