With the continuous development of the social economy, the city has a chaotic image of unwarranted expansion, so the proposal of compact cities and stock planning has been very important. Land for public service facilities is a major component of urban functional land, so it can be used to reflect the compactness of urban land. Based on the background of compact city, this paper analyzed the service efficiency of public service facilities land in Changchun City, including land for educational and cultural facilities, sports facilities, medical and health facilities and social welfare facilities.

In order to consider the behavioral factors of human beings, these results were divided into suppliers, suppliers and demanders for comparative analysis, and the influencing factors and their interrelationships leading to these results were obtained. At the same time, this gave specific suggestions on regional control, spatial structure compactness and spatial element allocation from the macro, meso and micro levels.
