The invention discloses a method and a system for quickly analyzing a message protocol based on the free label splicing technology, and belongs to the technical field of communication. The method comprises the steps: decomposing a message into label modules; analyzing the structural composition of the message, and determining the overall byte length of the message; splicing and analyzing the fixed message header by using the message header label; using separator labels to splice and analyze fixed data; splicing and analyzing the data required by the user and carried in the message by using a data bit label; using an end symbol label to assemble and analyze an end symbol and a check code at the tail of the message; configuring a label sequence, checking whether the length of the spliced message is consistent with the length of the whole byte of the message or not, checking whether a check code is correct or not, and if not, sequentially checking whether the splicing of each label is correct or not; and after t
