The present invention provides a method for data linkage driven by an event, used for data interaction between a first platform and a second platform. The second platform stores shared information and the method comprises: determining which platform the received event is from; forwarding a data packet from the second platform to the first platform for logical operation processing when the received event is from the second platform; when the received event is information from the first platform that at least includes a shared information operation instruction resulting from logic operation processing of data packets in the first platform, returning a shared information operation instruction completion message to the first platform, meanwhile forwarding the shared information operation instruction to the second platform so as to complete the shared information operation on the second platform. Therefore, the first platform acquires data synchronously without waiting for feedback of the second platform.
