在全球化的浪潮之下，政治學的關注焦點逐漸從中央轉向地方。其中一個重要的領域即為政治經濟學框架下的全球城市研究。大型的全球城市政府如何具體呼應權力移轉的論述？以全球城市所組成的全球城市體系中，各種不同的城市功能，如吸引外資與提升軟實力文化可否兼顧？都是值得深究的議題。於此同時，文化創意產業的興起，廣受全球各大城市關注。在產業呈現上，文創產業以群聚的樣貌，出現在許多城市之中。此一熱潮的出現很快就帶動了相關研究。因著可觀察的群聚現象，群聚理論一時之間成了研究文創產業的顯學。在政策面上，群聚理論認為，輔助型與刺激型兩種政策能對產業群聚有所助益。然而文創群聚後續普遍所面臨的衰退現象，使其遠離群聚理論中的理想群聚，理論的政策觀點也無法對此提出解釋。本文重新導入全球城市研究的觀點，以中國的指標性全球城市–上海為例，從城市政府的能動性檢視其對文創群聚所造成的影響。政府透過設立文創群聚來提升地租，從中達成吸引資本與擴充財政收入的目標。文創產業雖能拉抬地租，但地租的拉抬最後卻也使其被商業活動取代而失去生存空間。儘管此動態過程所造成的結果在許多研究中受到惡評，但本文也發現，以確保產業自主為前提下，與商業活動的適度聯繫，能夠促使文創群聚運作活躍，更趨近於群聚理論所描述的群聚。而本文最後的研究成果，也正得以回應權力如何具體移轉以及不同的全球城市功能可否兼顧兩大疑問。 / The focus of political science has shifted gradually from central government to local government since the wave of globalization. One of the important fields in political science is global city research, which is under the framework of political economy. How do global cities respond to the transition of political power? Can a global city, which is situated in the global city system, maintain more than one global city functions, such as attracting foreign investment and developing soft power like culture? Both questions are issues worth analyzing. Meanwhile, the trend of cultural creative industry draw many cities’ attention. Most of the cultural creative industries are clustered in the city. Such prosperity soon led to increasing researches. Cluster theory became the main research approach due to the appearance of clusters. On the policy side, cluster theory points out that both helping policy and stimulating policy are beneficial to industrial clusters. However, the reality reveals that many cultural creative clusters face difficulties and decline, which cannot be explained by cluster theory. This thesis takes Shanghai, a significant global city in China as example to analyze city government’s autonomy and its’ impact on cultural creative clusters through global city approach. In this case, city government improves the land rent by setting cultural creative clusters. The movement helps government gain plentiful fiscal profit. However, after the land rent has been improved, cultural creative industries will be replaced by commercial activities and lose their living place during rent improving period. Such result was criticized in many previous researches. Nevertheless, in the precondition of industry autonomy, the Shanghai case finds out that appropriate connections with commercial activities foster the mechanism of cultural creative cluster, which is close to cluster theory. The final result of this thesis responds exactly to the two questions about power transition and global city function.
