The invention relates to engine control and aims to solve the problem that an existing excavator group cannot be stopped at a proper time to save energy during idle speed waiting. The invention provides an automatic starting and stopping control method and system for an excavator engine, and the control method comprises the following steps: collecting operation data, uploading the operation data to a big data analysis platform, analyzing and determining target excavators working in the same region under the same working condition, and sending the idling ratio of a computer group to each target excavator; the target excavator displays shutdown information about whether the engine is shut down or not on an instrument according to the state of the target excavator and the machine group idle speed ratio; controlling the engine to flame out or operate according to the instrument selection instruction; after flameout, a pilot operation signal is detected to automatically start the engine; according to the overall b
