Research On Equity Allocation Model Of Leader-Follower Investment Model Under The Background Of Blockchain

As a part of crowdfunding,equity crowdfunding has the characteristics of low participation threshold,high return and high risk,which brings more investment options to investors.With the development of blockchain technology,the platform of equity-based crowdfunding based on blockchain technology is widely used.Although the existing platform of blockchain can solve some problems,such as information can not be tampered with,improve the credibility of the platform.But there is still a phenomenon that ordinary investors can not be protected when their rights and interests are damaged.Therefore,under the background of blockchain equity crowdfunding platform,we propose to apply the lead-follow up investment model on the blockchain platform and establish a dynamic equity allocation model based on the Shapely value method(DEA-SV model)to further reduce the damage to the rights and interests of ordinary investors.In the DEA-SV model,we distinguish the static and dynamic factors that affect the equity allocation during the entire project management period.The static factor considers the capital investment and risk commitment of each participant,and divides it into 8sub-indicators;the dynamic factor considers the work effort of the project financier and the project leader in the project management stage,and quantifies it into project completion degree and leader completion degree.The model shares the initial equity according to the static index;in the project management process,dynamic index is used to modify the allocation of shares.In addition,we design the parameter decision algorithm applicable in the DEA-SV to ensure the fairness and fairness of the parameter decision-making process.Subsequently,in order to apply the DEA-SV model to the blockchain platform,we designed the DEA-SV contract model from the perspectives of participant role,role behavior,information model,control logic and process,and introduced the process in detail.Finally,according to the IDE provided by Ethereum,the DEA-SV contract model is applied to simulate the whole process of company from project financing to project completion and the equity share of participants during the period.Finally,the influence of the change of expected return,risk-taking,project completion degree and leader completion degree on the change of participant's equity in the model is discussed.Through the application and discussion of DEA-SV model,the initial allocation stage of the equity considers the input and risk-taking and combines the Shapely value method to ensure the rationality of the initial equity allocation process.The equity revision allocation stage considers the project completion degree and The lead completion degree,which ensure that the ordinary investor canparticipate in the work as supervisor.This enables investors to find out the inadequacy of project managers and reduce the damage of rights.Adding DEA-SV model to the blockchain platform helps to protect the basic rights and interests of investors,and reduces the losses of ordinary investors.
