The invention discloses a large-scale network information propagation calculation method and device based on a distributed platform. The method comprises the following steps of: constructing a configuration network according to network parameters; Constructing of information propagation model, selecting to set parameters of a network and an information spreading model according to requirements; Configuring information format, Individual attributes, Message transfer function, The method comprises the following steps: carrying out iterative computation on a message fusion function, a message processing function, an input network, an information format, an individual attribute, a message transfer function, the message fusion function and the message processing function through a parallel distributed platform, and screening out nodes with propagation activities in a network containing propagation records and connected edges of the nodes to obtain the propagation records and outputting thepropagation records. The method has the advantages of being high in parallel computing capacity, high in user customization capacity, good in propagation computing universality and adaptability and simple and efficient in development process, the development difficulty of parallel distributed computing can be greatly reduced, and the problem of parallel distributed storage does not need to be additionally considered.
