Disclosed is an apparatus for extracting a value chain based on transaction data and a method for extracting a value chain using the same. The apparatus for extracting a value chain based on transaction data of the present invention includes: a communication unit receiving a request for extracting a value chain based on a master node from an external terminal; And Communication unit for transmitting and receiving transaction data with the external first server, and transmitting and receiving transaction history data with an external second server; And electrically connected to the communication unit, and when the communication unit receives the transaction presence data from an external first server, extracts a candidate node associated with the master node, and the communication unit performs transaction details of the candidate node from an external second server. Upon receiving data, extracting the input factor group for the candidate node, and updating the training data one or more times based on the received transaction history data, through the machine learning, the input factor group of the candidate node It may include a control unit for extracting the relevance of the candidate node from, and extracting a sub-node among the candidate nodes based on the relevance of the candidate node.
