Research On Information Spread Model Of Charitable Crowdfunding Based On Information Trustworthiness

With the development of Web2.0 technology and mobile internet,charitable crowdfunding has become a new public charity donation that distinguishes itself from traditional public fundraising platforms and offline fundraising.According to the Crowdfunding Industry Report in the first half of 2017,the total number of charitable crowdfunding projects is 7,454,the number of successful projects is 4,464,the amount of funds raised from successful projects is 150 million,and the number of successful fundraisings is 15,958,600.Charitable crowdfunding,after being published on related platforms,is spread and developed through third-party social platforms.It mainly affects the behavior of potential supporters through the project information that can be shared by relationships in social networks.For this reason,this article mainly starts from the crowdfunding information dissemination element,the information dissemination model,the project information trust degree calculation in the example analysis.The main research contents are as follows:(1)This article focuses on the characteristics of online public interest crowdfunding in social networking and abstracts out the main influencing factors in the crowdfunding development process.The degree of trust in project information mainly influences individual behavior as the main influencing factor.At the same time,it considers the social capital of project sponsors,the characteristics of third-party social platforms,the project duration,and the contribution of individual behavior.(2)Based on the information dissemination model,build a model that meets the charitable crowdfunding characteristics.According to the propagation mechanism of the model,the effects of various elements in the model are analyzed through simulation and numerical simulation.The measurable indicators of dynamically demonstrate the role of various factors in the project duration and scope of donation.The results show that in project information dissemination,reducing discarding behavior is more important than crowdfunding project information trustworthiness and in order to increase the proportion of donations,it is more important to increase information trustworthiness.(3)Taking the project real data as an example,it analyzes the characteristics of the crowdfunding project duration.Through actual data analysis,it is found that the project cycle mainly presents three stages: the outbreak period,the stationary period,and the warm-up period.That is,in the early period of the project,there was a rapid growth in the short-term,showing an outbreak of donations;in the medium-term,it grew slowly and showed a steady trend;in the later period,the growth rate accelerated and showed a growth trend.After comparing with the model result,the validity of the crowdfunding information dissemination model is verified.(4)In addition,using textual information of the charitable crowdfunding as the main dimensions,through textual emotional intensity calculations,the project actual duration development trends with different project information trust are analyzed and compared.The comparison results verify the importance of information trustworthiness in charitable crowdfunding.
