Kaohsiung is transforming from a city of heavy industries into one of service industries, the rate of unemployment and adjustment of industry structure are becoming the real challenges for local development. During WTO and the 2009 World Games, moreover, Kaohsiung is expected to rise to the challenge of risks. Meanwhile, demand of citizens in Kaohsiung are not fully corresponded to public policies made by central government, and most of the people don¡¦t care as much as should local affairs because of lack of effective communications between public and private sectors. Therefore, in city marketing efforts, it would be more important to encourage participation and integrate multiple sectors¡¦ opinions as ¡§internal marketing¡¨ rather than just trying to attract businesses to the city. An integrated public affair management(PAM) framework(Wang et al., 2003)is adopted to describe situations in the pluralistic societies. Then we introduce the Cognitive Continuum Theory(CCT) adopted by Hammond et al., (1987) and Interactive Management (IM) technique developed by Warfield (1994). Results of studies are: 1) the problems of Kaohsiung¡¦s local development on structure of industry, human resource and port of Kaohsiung, 2) in the CCT studies there exist quite a few differences of cognition and modes of cognition presented tend to ¡§intuition¡¨ or ¡§analysis¡¨ between limited information, and 3) the IM analysis include competitive strategies for Kaohsiung¡¦s local development and an problematique diagram to demonstrate the structure of strategies. The conclusion is that, although there exist diversities of opinions among multiple stakeholders in Kaohsiung, they can be quite effectively addressed with the IM technique. Methods and results introduced and used here should be of value to relevant agencies about public forum and citizen conference.
