| Since Tnnies, German sociologist, puts forward the concept of community andCharles March, UK sociologist, and Hannah Arendt, American political philosopher,respectively put forward the concept of public space, the two words, which have the mostdifferent meanings, have been Rashomon of each researcher. Researchers fail to reachconsensus, because both community and public space involve in sociology and space,which always change with social background, academic perspective, research method, andvalue.The current sociology is developing toward structured research of integration ofwhole and individual, subjective and objective and value and tool. It is themainstream to conduct social research in light of relationship. Affected by direction changeof social research, the research perspective on unban community and public space alsochanged: from research of single material environment to interactive research of materialand immaterial environment (including social relationship). It pays attention to therelationship between space and space, between space and human, as well as betweenhuman and human. Social network is a set of theories which analyzes the relationshipbetween individual and individual, with a focus on relationship and relationship mode,regardless of the attribute of actor. Therefore, it is an important perspective to investigatepublic space of current urban community. Under social network perspective, theconnotation and characteristic of China’s urban community and public space changed dueto the influences of the reforms of economy and social system: community no longer onlyrefers to spatial communities. Instead, it consists of numerous, special and interest-basedcommunity members[]; the social community space no longer only refers to simplephysical scope; instead, it refers to the important carrier of community social network andplays a role of bridge in citizens’ social life and public life: at the same time, the effectiveappraisal standard on social public space also needs to change: from the standard ofquantity, dimension, and form to promoting healthy development of social network as mainjudgment basis, including enough extension and integration ability. That is to say: thecommunity public space under social network prospective is not naturally reasonable.Improper space forms will cause many bad influences on the relationship network ofcommunity. Therefore, compared with detailed design method, it is more important toestablish a standard, which regards quality of social network as core, to judge theeffectiveness of community public space, especially for the community public space which is transformed and has complex social networks.Firstly, the paper integrates relevant theories and methods of social network includingbasic theory of social network and analysis method of social network, with the researchmethods of complex network, forming a comprehensive social network perspective.Besides, it puts forward ten theoretical hypotheses concerning the development trend ofcommunity social network as well as relationship between community social space andpublic life. Secondly, it uses public life as intermediary agent to construct effectivenessanalysis framework which mainly utilizes the interactive relationships as main factors,including public space (space and space), public life (space and human), and social network(human and human). Then it carries out analysis and evaluation on the effectiveness ofthree representative transformed communities and the public space, respectivelydisplacement type, partial transformation type and protection type. Last but not least, itsummarizes and deeply analyzes the evaluation results. On one hand, it conducts empiricaltest on the above theoretical hypothesis; on the other hand, it summarizes the law ofinteraction between transformed community social network and public space, so as topropose a set of design strategies for public space of transformed community on theoreticaland empirical basis and apply it in practical situations. |
