Abstract:The development of the internet economy brings opportunity to build the cloud credit evaluation model. On the basis of literature review, we built the logic of relations among the financing difficulties of technological small and medium-sized enterprise, lack of information, the information asymmetry, and cloud credit evaluation model. And we found that the credit evaluation model of small and mid-sized enterprise has some problems, including scattered information, the single data source and single object. Cloud credit evaluation model is based on the cloud innovation concept which is open, sharing, equality and efficiency. That integrated huge amounts of information, with the support of big data and cloud computing technology, through the information sharing mechanism and benefit distribution mechanism to realize all kinds of credit model resources to be integrated. The model can effectively solve the problem that small and mid-sized enterprise is short of credit data, and ease the information asymmetry between supply and demand of funds, in order to meet the financing needs of small and mid-sized enterprise and improve the allocation efficiency of the industry.
