The invention discloses a zero position correction-based MEMS accelerometer. The zero position correction-based MEMS accelerometer comprises a substrate; an oxide layer is arranged on the substrate; aplurality of anchor points are fixed on the substrate through an oxide layer; a sensitive device layer is arranged on the oxide layer; the sensitive device layer comprises a differential capacitancedetection structure, an accelerometer closed-loop feedback electrode structure, a plurality of cantilever beams, a zero position correction structure, a sensitive mass block, two stopping structures and two fixing structures; the structure of the accelerometer is properly designed, so that the problem of the inconsistency of the change of the zero position output of the structure of the accelerometer caused by machining error, installation error, environment temperature and the like can be solved, and the influence of zero position change on performance such as device stability, temperature characteristics and the like is eliminated.
