Research On Multi-Subject Supervision Of Pre-Sale Capitals Of Commercial Residential Buildings Based On Blockchain

In the current pre-sale capital supervision practice,the information in the supervision process is not transparent enough,and it is difficult for the pre-oeders to participate in,and the adverse events of misappropriation of pre-sale funds still often occur,resulting in a bad social impact.On the other hand,the tightening of pre-sale capital supervision policy has further compressed the capital liquidity of real estate enterprises,affecting the long-term development of enterprises.Therefore,this study focuses on promoting the efficient and compliant use of pre-sale funds,and conducts research from three aspects: identifying diversified subjects of pre-sale funds supervision,introducing blockchain to enrich regulatory means,and proposing relevant regulatory strategies.In the qualitative analysis of this study,NVivo 11 software is used to summarize and analyze the interview content,sort out the current situation of pre-sale capital supervision in current practice,analyze the way of participation of pre-purchase parties,determine the subject and process of pre-sale capital supervision,and propose to build a blockchain supervision information platform to promote information transparency.Secondly,based on design science research,Hyperledger Fabric V2.2 is used to build a blockchain regulatory platform to enrich regulatory means and ensure that the proposed multi-subject regulatory process can be realized.Finally,a four-party evolutionary game model of pre-sale capital supervision under the platform of blockchain supervision is constructed,and the application effect of blockchain supervision platform is determined through game solving and simulation analysis,and relevant strategic suggestions are put forward for the supervision process.Through the qualitative analysis,platform building and game analysis,this study shows that through the block chain technology can effectively assign multiple subject commodity house opens to booking a capital regulation:(1)in the regulatory body,regulate Banks,the government departments should take supervision main body responsibility,pre party although not directly become one part of the money to apply for examination and approval,but can improve participation by regulatory platform to understand information.(2)in terms of regulation means,platform to realize the supervision of chain block cooperation between Banks and government departments to coordinate and improve the efficiency of capital regulation,promote real estate enterprises pre-sale service efficiency of funds,improve the guarantee under the condition of real estate business privacy for pre party regulatory transparency,provide effective means for supervision of the implementation of the plural.(3)in the regulatory strategy,respectively from the block chain platform,government departments and pre involving aspects put forward the corresponding countermeasures and Suggestions,the first thing to strengthen block chain platform can be integrated with the existing system,further enhance the platform utility,second to government departments to strictly implement the regulatory authority,strengthen the violation penalties,promote compliance pre-sale funds,Finally,we should strengthen the pre-purchase party’s main body supervision and participation,and play a subjective active role.The main contribution of this study lies in :(1)analyzing the role of different subjects in the supervision of pre-sale funds,and determining the multiple subjects and procedures of supervision;(2)Build a blockchain supervision platform and solve traditional problems by applying the decentralized governance logic of blockchain technology;(3)Promote the compliance and efficient use of pre-sale funds from the three levels of regulatory subjects,means and strategies.
