people interact with the urban environment and its heritage. Urban Design Urban renewal involves changes in the physical and functional aspects of cities as a response to urban design;it is a process of making decisions about the location and physical fabric of investment in the built environment and the adaption of these decisions to functional and aesthetic ends(Couch,1990).Urban design is a broad idea that addresses issues in planning sub-system for sustainable urban renewal.A series of studies focused on these issues for sustainable urban renewal in Hong Kong and identified critical factors for enhancing social, economic and environmental sustainability (Lee and Chan,2008b;Chan and Lee, 2008a;Chan and Lee,2008b). Stakeholders and Community Involvement Stakeholders The various stakeholders in urban renewal projects include local,state,and national officials in both environmental and economic development departments, as well as those in the private sector,both institutional and individual,who seek to place capital,reduce risks,gain profits and enhance their reputation;in view of the possible impact on their health and quality of life,the public living in close proximity to urban renewal projects should also be included.The urban renewal policy,process and project implementation are greatly influenced by the relationship between these different stakeholders,the characteristics of different partnership modes,as well as the power,mechanism,and operation of different agents.Different stakeholders guide sustainability in different situations.Under some circumstances planners take a lead,while under others it may be the developers.It's important to remember that stakeholders do not have equal rights and powers in the renewal process. Government plays the most important role in the governance structure of urban renewal,which directly influences the planning strategies involved.When studying sustainable urban renewal,some scholars pay attention to the governance structure.In the UK for example,the transition of the governance structure from a traditional hierarchical government to new forms of governance in was discussed and the Thames Gateway regeneration project was examined in terms of its institutional context and the relationship between traditional and new forms of planning.The analysis suggested that traditional forms of planningpeople interact with the urban environment and its heritage.
