The invention discloses a piston type expansion compressor based on electromagnetic induction. The compressor comprises an expansion compressor cylinder body, a cavity formed in the expansion compressor cylinder body, a permanent magnet piston arranged in the cavity and an electromagnetic induction coil layer arranged in the expansion compressor cylinder body and used for pushing the permanent magnet piston to move or converting kinetic energy of the permanent magnet piston into electric energy. A low-pressure working medium chamber and a high-pressure working medium chamber are arranged at the two ends of the cavity in a one-to-one mode, and the low-pressure working medium and the high-pressure working medium alternately enter and are discharged out of the cavity in the reciprocating motion of the permanent magnet piston to complete compression of the low-pressure working medium and expansion work of the high-pressure working medium; the invention further provides an application system and method of the pist
