Statistical method and system for counting working efficiency of workers

The invention discloses a statistical method and system for counting the working efficiency of a worker. The method comprises the following steps: establishing and storing a plurality of motion models in a data server; when a worker performs farming work, the positioning device determines whether the worker is located at a designated place or not according to the coordinate position of the worker; the network communication module is used for timing working hours; acquiring at least one displacement coordinate of a designated part of the worker through a displacement acquisition device within the time interval; the working efficiency analysis equipment obtains an actual motion track, counts the same frequency of the actual motion track and the motion model and quantized working results, and calculates the motion model index efficiency and the working result index efficiency of the worker; and a manager formulates a management scheme through the index efficiency of the motion model and the index efficiency of t
