Research On Allocation Strategies For Market Factors Of Electric Carsharing

After 2008 global financial crisis,driven by internet information technologies,sharing economy has been an intensively concerned economic activity recently.Sharing economy breaks through the restrictions of ownership,enabling supplier and demander to trade on the right to use directly.This business model activates idle resources,promotes economic efficiency and reduces waste phenomenon.As the most active branch of sharing economy,transportation field is the earliest practice of sharing economy activity.In the context of oil crisis,air pollution and transportation resources deficiency,as a novel business model,electric carsharing has offered a feasible solution to the sustainable development of transportation field.Electric carsharing is the fusion of electric vehicle,sharing economy and internet plus,and it meets people's diversified travel demand.Despite of the wide application prospect,electric carsharing is still a best game no one played nowadays.It is a major concern to break through the bottleneck at market level,push forward the progress of electric vehicle industry,and advance the development of carsharing industry.VIP(Vehicle,Infrastructure,Parking lot)are the constituent factors of electric carsharing market and this paper tries to investigate into the strategies for these market factors.The main contents of this paper includes:(1)Carsharing pricing: A carsharing duopoly market pricing game model with horizontal difference and vertical difference based on random utility theory is established.The existence and uniqueness of equilibrium price is proved,and the effect of parameters to equilibrium price is analyzed.(2)Vehicle relocation: The relationship between optimal price and price elasticity of demand is analyzed,and the effects of vehicle shortage to economic surplus is discussed.The vehicle relocation models according to no relocation,operator-based,user-based mode are established,the iso-profit curve of these modes with unit labor cost and base price elasticity of demand is characterized,and the applicability of these modes is determined.(3)Location and pricing of charging station: Hotelling models with demand varied with distance between user and charging station are established,and the location and pricing problems,when price is fixed,location is fixed,price and location are not fixed,are analyzed.Especially,the relationship between iso-utility point and market range is discussed,the equilibrium solutions and the existence conditions of these are obtained.(4)Capacity allocation of charging station: Service quality is defined as service efficiency and service reliability,the varied process of battery energy storage system's remaining capacity with the charging demand of visiting electric vehicles is characterized by Cramér-Lundberg model.The relationship between service quality and relevant parameters is obtained,and the optimal initial allocation of charging station is determined.(5)Parking lot sharing: Two sharing modes are proposed: operators mutually share their parking lots,operators form a coalition and share the cost of parking lot aquired from the third party.The condition that operators mutually share their parking lots is analyzed,various cost sharing models in cooperative game are applied to solve the problem that operators form a coalition and share the cost of parking lot aquired from the third party.
