High　cost　and　low　milk　yield　per　dairy　cow　are　current　problems　mainly　faced　by　dairy　farms　in　China.　Thus,　optimizing　the　regional　layout　and　integrating　the　advantages　to　enhance　the　competitiveness　of　dairy　farming　in　China　is　necessary.　However,　existing　studies　on　comparative　advantage　analysis　of　dairy　breeding　have　a　relatively　single　perspective.　Therefore,　comprehensively　identifying　the　advantage　area　of　dairy　farming　is　difficult.　This　study　established　a　comprehensive　evaluation　model　of　the　comparative　advantages　of　dairy　farming　considering　basic,　technical,　economic,　and　feed　resource　indexes　using　linear　weighted　and　entropy　weight　methods.　On　this　basis,　the　spatial-temporal　analysis　of　the　comprehensive　evaluation　on　comparative　advantages　of　dairy　farming　from　2013　to　2017　was　performed　using　Geographic　Information　System(GIS).　Finally,　the　advantage　areas　of　dairy　farming　were　identified.　Results　demonstrated　that　the　highest　average　comprehensive　evaluation　value　was　0.6017　in　Inner　Mongolia　Autonomous　Region,　followed　by　0.5355　in　Ningxia　Hui　Autonomous　Region　and　0.1786　in　Anhui　Province.　Furthermore,　the　advantage　areas　of　dairy　farming　were　identified　including　Inner　Mongolia　Autonomous　Region,　Beijing　Municipality,　Heilongjiang　Province,　Shanghai　Municipality,　Xinjiang　Uygur　Autonomous　Region,　Tianjin　Municipality,　Liaoning　Province,　Shanxi　Province　and　Ningxia　Hui　Autonomous　These　findings　provide　references　for　the　spatial　layout　of　dairy　farming,　spatial　allocation　of　production　resources,　and　sustainable　development　of　animal　husbandry.
