[Purpose/significance] The supply chain logistics information ecosphere model based on block chain is constructed to promote the sustainable development of supply chain logistics information resources management. [Method/process] Combining with the block chain definition,the basic framework model,and the key technologies and characteristics,this paper studies the coupling relationship between the block chain and the supply chain logistics information resources in the subjects,the transaction mechanism and the intelligent contract. Moreover,block supply chain logistics information resources management is analyzed from objects,attributes and functions. [Result/conclusion] The paper establishes a supply chain logistics information ecosphere model based on block chain,and improves supply chain logistics information ecology. [Limitations]The empirical study on supply chain logistics information ecosphere model based on block chain needs to be deepened.
