The invention relates to the technical field of earthquake safety assessment, and provides a site earthquake safety assessment method and system based on full-period MR estimation, and the method comprises the following steps: calculating the contribution probability of each potential seismic source region according to the bedrock peak acceleration and bedrock acceleration response spectrum of an engineering site, and calculating the contribution probability of each potential seismic source region; determining a value range of an expected magnitude M and an expected distance R; the expected magnitude and the expected distance are estimated according to the peak acceleration and the response spectrum, and in the maximum contribution potential seismic source area, according to the principle of accurately meeting the peak acceleration and approximately meeting the response spectrum, the expected magnitude and expected distance combination with the best response spectrum matching is estimated; and based on the ob
