本文旨在討論「修訂臺北市綜合發展計畫：中正區、大安區地區發展構想」之規劃過程及其計畫內容。為兼顧計畫之全盤性與現實性，規劃者一方面從歷史、社會、產業、空間等四向度分析城市中心性，另一方面舉辦多場座談會以掌握市民的期待與需求，從而建構了不同歷史階段下多元的、複雜的、動態的城市中心。中正區與大安區扮演不同的區域角色：中正區自臺北建城以來即是漢民族的歷史的、政治的象徵中心；大安區堀起於二次戰後，八０年代以後成為臺灣地區最有活力、最具企業創新性的企業中心。 然而，各項指標則顯示近年來中正大安區的中心性優勢正逐漸衰退，對於臺北市蹐身全球城市的目標，這無疑是項警訊。同時，服務不足且多樣化不夠的都市公共設施——例如未盡方便的大眾運輸系統，未充分用於休閒、遊憩、資源保育的綠帶與藍帶，以及可創造社會互動卻被忽略的社區活動中心等——亦使得臺北在這場資本主義城市競爭體系中，處於不利位置。 緣此，為維繫並創造中正大安區的優勢條件，「中正大安地區構想」案研擬「策略性綱要計畫」作為地區發展的依據。其中，以行政、企業、人才培育三體系的整合﹐作為主要目標；而將這個目標轉化為實質建設，尤其是如何靈活利用公有土地作為社區、企業發展的契機，則是主要的行動策略。

　　　　　This article talks about the planning process and the strategic guideline plan for the Chung-cheng and Ta-an Districts of Taipei. Studying the area more comprehensively and allowing its citizens to participate in making sense of reality are two different approaches to the planning process. Comprehensive study involved four aspects of the area--the historical, social, industrial, and spatial dimensions. The planners also held several meetings to keep in touch with different groups supposed to reflect general public interests in the area to find out their demands and requirements. An image of a divergent, complicated and dynamical urban centrality in different historical stages was thus constructed: the Chung-cheng District and the Ta-an District play different roles. The Chung-cheng District has been a symbolic center of history and politics since Han people built Taipei City 119 years ago; The Ta-an District, a newly rising area after World War II, has become the most active and innovative enterprise center of the service industry in Taiwan. However, the indicators of centrality show that this area has been losing its advantage over the last few years, especially in the productive service industry. This is a warning sign for Taipei's ambitions to become a global city. In addition, the lack of high quality public services, such as an efficient and convenient mass transportation system, green and blue areas for leisure, recreation and resources preservation, active community centers to create more social interaction between people and so on, also make it difficult for Taipei to compete with other metroplises in a competitive capitalist system. This is why in order to maintain the advantages of this area, a major goal of the strategic guideline plan is to integrate the bureaucracy, the enterprise system and the high quality labor training system. Furthermore, transforming such integration into physical plans, especially how to use actively and efficiently public land to raise the environmental quality is the most important strategy. After all, this strategic guideline plan is to lead following plans to make the goals come true.
