Research On Network Expansion And Layout Of Shared Electric Vehicle Network Based On Network Effect

Since the 1990 s,the rising price of motor fuels and the continuous deterioration of urban traffic has made it necessary to innovate in the transportation sector.With the development of mobile internet technology,it is possible to establish a customer-friendly,control and efficient vehicle sharing assistance system.The report on the 19 th National Congress of the Communist Party of China clearly stated that it promotes the deep integration of the Internet,big data,artificial intelligence and the real economy,and fosters new growth points and new kinetic energy in areas such as innovation leading,green low carbon,and shared economy.Therefore,in order to better meet the daily public travel needs of consumers and foster new kinetic energy of friendly and intensive economic growth of the field of transportation,innovation promotes the integration of “Internet + electric vehicles” and creates a transportation that integrates green,lowcarbon and shared economy.Service supplies model,it is necessary to speed up research and explore the business model of electric vehicle timeshare leasing.This study aims to research the shared electric vehicle business model,mainly analyzing the scale expansion and network competition.Firstly,the characteristics of the shared car rental network expansion are studied.By introducing the network effect,the shared electric vehicle rental profit models is constructed,and the profit characteristics of the single rental network of the expansion of the rental network are analyzed,and the minimum critical point and maximum supply of various outlet’s are calculated.Secondly,on the basis of exploring the network expansion mechanism in the early stage,the profit of the leased network under different network structures is discussed,and the layout strategy of the electric vehicle is shared.A two-step clustering firefly algorithm is proposed,which not only improves the early stage of the algorithm.The efficiency and accuracy of the search,and by categorizing the candidate sites,the layout order for each candidate dot can be conveniently identified.Finally,the paper explores the market strategy of sharing the development of electric vehicle enterprises,and constructs the consumer surplus function by taking the convenience of renting and returning,bicycle driving experience and rental price as the influencing factors,and studying the sharing monopoly market of electric vehicle companies.The duopoly market has entered the market and entered the market together,and the strategic choices of renting and returning convenience,bicycle driving experience and rental price,in order to analyze the scale of the rental network and the choice of rental models in different market scenarios.Decisionmaking behavior in terms of rental prices.The study found: First,under the combined influence of positive and negative network effects,various outlet’s exhibit different profit characteristics.When the network externality dominates,the marginal profit of the leasing network show a trend of decreasing first and then increasing from the expansion of the network.When the leasing network is dominated by negative network externalities,its marginal profit will increase first and then decrease from the network expansion.Second,the network layout is affected by the path dependence effect.The order for different types of outlet’s will have an impact on the profit of the entire network.When you first set up a network that is greatly affected by the externality of the network,the accumulated profits of the network will be higher.Third,in the state of different shared leasing networks,the market competition strategies of the various shared car companies are different.In the case of a complete monopoly,sharing car companies will not occupy the entire market due to the size of the network expansion.In the oligopolistic market scenario,if the company enters the market successively,the strategic choice and market share of the participating shared car companies will be greatly affected by the network layout and price strategy of the first-time company.If two shared car companies enter the market at the same time,their leasing price and consumer price elasticity of each leasing car brand have a greater impact on their respective market shares.This research provides a theoretical basis of the empirical research and vehicle scheduling for outlet layout,and provides basis and reference for the policy formulation of relevant government departments and the design of related enterprise competition strategies.
