The invention provides a graph neural network-based property right transaction recommendation system and recommendation method for a click-to-beat network, and relates to the field of property right transaction. The method is based on a property right transaction platform matched with big data. The system comprises a registration module, an investment attraction module, a transaction module, a recommendation module and a data storage module. The user browses in the investment attraction module after registration, the recommendation module generates a relation graph between the user and a target based on big data to form graph data, the graph data is trained based on a graph neural network to obtain recommendation data, and the recommendation data is displayed in the investment attraction module to recommend a property right project to a buyer and improve the transaction speed of the property right project; and the recommendation module uses a recommendation mode based on a graph neuralnetwork element path, so that the recommendation accuracy is improved, and a recommendation reason can be clearly given.
