Abstract The invention provides a method for calculating a site response in an earthquake by considering a medium quality factor, and relates to the technical field of earthquake engineering and geotechnical engineering. The method comprises the following steps of selecting a research area with a similar structure, and collecting horizontal seismic records of all bedrock sites; obtaining east-west and south-north Fourier amplitude spectrums of the bedrock sites; calculating east-west and south-north quality factors of every two bedrock sites; obtaining the medium quality factor with a form such as Q(f)=Q0fn; and calculating the horizontal site response of the research site in the earthquake. According to the method for calculating the site response in the earthquake by considering the medium quality factor, provided by the invention, the absorptive attenuation effect of the quality factors on earthquake waves is considered; when a hypocentral distance of a reference site and a hypocentral distance of the research site
