Application of the Internet of Things and Blockchain to Clarify Information in the Financing of the Supply Chain of Businesses

The main factor in successful supply chain financing services is the use of business-oriented information systems. The current research aimed to further associate blockchain technology with the Internet of Things (IoT) and apply them in the field of supply chain finance. The research presents a new information management framework based on blockchain technology and IoT, which contributes to information transparency in the supply chain financing process. By managing information based on blockchain technology and IoT, the operational cost of the entire supply chain can be greatly reduced due to the integration of capital, information, and commercial flows in the supply chain. The results can be summarized as follows: (1) In a symmetric information environment subject to the limitation of maximizing the expected return of all parties, the incentive subsidy under the compatible incentive mechanism has a positive relationship with the maturity of blockchain technology and the operational capability of small and medium-sized enterprises (SMEs) and a negative relationship with the action level coefficient, absolute risk aversion coefficient, and external uncertainty of these companies. (2) The expected income that satisfies the mechanism of incentive compatibility has a positive relationship with the maturity of the blockchain technology, the broker’s profitability, and the net profit received by the employer. (3) In an asymmetric information environment, a varied incentive subsidy is more effective than an equal incentive subsidy in different SMEs with different operational capabilities and provides different incentives for these companies. Therefore, it can be concluded that in a symmetrical information environment, the equal incentive subsidy is more effective, but in an asymmetric information environment, a varied incentive subsidy is more effective.
