Here, we estab- lish an indicator system including internal subsystem （economic production, resources consumption, waste emis- sions, and waste recycling）, external subsystem （industry correlation） and mutualistic subsystem （society devel- opment）, and use AHP modeling to evaluate the period from 2000 to 2013. We found that the development of the service sector circular economy in Beijing experienced an increase from 2000 to 2008, then a decrease from 2009 to 2013. This change mainly resulted from the decrease in Beijing＇s GDP following the international financial crisis in 2008. The internal subsystem greatly influences the service sector circular economy：synthetic weight of eco- nomic production, resource consumption, waste emissions and waste recycling was 0.367,0.136,0.136 and 0.075, respectively. Within the external subsystem, industrial correlation has a weak connection with Beijing＇s service sector circular economy with asynthetic weight of 0.143, this result illustrates that the development of the service sector circular economy has an intimate relationship with other cities or provinces around Beijing, such as Tianjin and Hebei. As are presentative of the mutualistic subsystem, society development has a positive nexus with the service sector circular economy with asynthetic weight of 0.143, proving that the development of the service sector circular economy can improve the service sector employment ratio in Beijing.
