The invention discloses a collaborative algorithm-based tooth shape matching method for an engine timing tooth-shaped chain system, and belongs to the technical field of automobile engines. The matching method comprises the following steps: determining a comparison coefficient k1 based on a driven chain wheel tooth width ratio and a positioning relation under a given chain plate tooth shape; determining a comparison coefficient k2 based on the existence limit of the tooth form of the driving chain wheel under a given chain plate tooth shape; and based on a collaborative algorithm, controlling the values of the comparison coefficients k1 and k2, and performing secondary adjustment to output tooth profile parameters. The method is suitable for timing tooth-shaped chain transmission systems of any forms, and a series of problems that the tooth shape is unreasonable due to the fact that the tooth shape matching degree of the system is too poor, and the chain is scrapped in advance, the chain wheel is abraded in a
