Abstract
The purpose of this study is to get knowledge for design of life space from a viewpoint of understanding of the living environment. We discuss here “social-exchange” and “identity.” On the social-exchange approach, firstly general view of social-exchange theory is shown. Secondly the relationship between social-exchange and community is discussed. Lastly evaluation indexes of community design by using the principles of social-exchange are given. On the identity approach, based on Imanishi's ideas on identity, the characteristics of identity in life space are defined. This study will contribute to the scientific and effective planning of identity and community.
