The aim is to explore Beijing residents’ social engaging/disengaging emotion by stratified sample of 800 residents of different communities of 16 districts. It was found that Beijing residents feel mild to moderate social engaging and disengaging emotion. Social disengaging emotion was more perceived than social engaging emotion，so does its effect on happiness. Compared to 2013 survey，social disengaging and engaging emotion increase while social disengaging emotion increase faster. At individual level，the gap between social disengaging and engaging emotion decrease along with ageing. The relationship between SES and social engaging/disengaging emotion is closer to U-shape that means low-SES and high-SES show different type of social engaging/disengaging emotion type though both of them feel similar explicit ones. At community level，people living in convenient community feel stronger social disengaging emotion than those not. Habitants feel stronger social disengaging emotion than immigrants from other provinces.

Then two proposals were suggested to maintain moderate social engaging/disengaging emotion.At first，Administrator could provide convenient psychological services by “platform+service sites”.Secondly，more convenience-related intra-structures could be done to facilitate residents’ work and life.
