| With the development of globalization,market competition has gradually evolved from individual competition to supply chain competition.As an important link throughout the product supply chain,logistics service has become the key to supply chain competition,and its status has become important.the raditional logistics service supply chain is mainly based on the simple integration of logistics information platform.Logistics service providers and integrators are relatively independent,logistics information is mostly ineffective,and even the situation of information error often appears.In recent years,as a new model of Internet + logistics development,logistics cloud platform can integrate all information of service supply chain providers and realize the digitization and networking of logistics resources.However,limited by the existing technology and management mechanism,the development of China’s logistics cloud platform is still in the initial stage.The uneven distribution of power and information asymmetry exist on the logistics cloud platform,which limits the willingness of enterprises to share information and is not conducive to the long-term development of logistics cloud platform.In view of this,this dissertation explored the information sharing problem of each node on the logistics cloud platform based on evolutionary game theory and built the logistics cloud platform based on blockchain technology.First of all,based on the cloud platform of logistics operation mode analyzed and literature reviewed of previous scholars,seven main factors affecting the information sharing of logistics cloud platform were summarized.And the information sharing evolutionary game model of logistics cloud platform was established,then the profit function of both sides of the game was used to analyze the influence of seven factors on the information sharing strategy,and the evolutionary stability strategy was analyzed.Secondly,the Matlab software was used for numerical simulation.,and by analyzing different influencing factors,it was found that each influencing factor had different effects on information sharing strategy,the degree of information sharing,sharing favorable information,collaboration index,and incentive index were positively correlated with information sharing strategy,the information sharing cost,information sharing risk,and opportunity benefit were negatively correlated with information sharing strategy.Finally,in order to encourage relevant enterprises to share information through the characteristics of the platform,and then promote the development of the whole logistics industry.The logistics cloud platform was built with block chain technology and its functions were summarized by analyzing the objectives and participants of the logistics cloud platform and combining the factors that affect information sharing. |
