城市產業的發展是否必然具有高度路徑依賴的特質？路徑依賴的概念長 期以來被大量用於解釋中國大陸城市產業的發展模式，但學者同時也強調國 家與地方政府重點策略推動的影響同樣不可忽視，這其中的矛盾和折衝又如 何獲得妥協與解決，始終是政治經濟學中備受關注的議題。 天津重化工業一直是其經濟成長的基礎，然而2010 年天津卻被列為國 家首批低碳城市試點，原來高碳消費之重化產業面臨轉型。如此巨大轉折究 竟如何產生？本文由路徑依賴途徑討論中央政府與地方需求之間的折衝，發 現天津近來的發展更符合路徑創造之解釋，尤其是中央政府在天津發展過程 中，不僅是城市發展監管者，同時也是促使城市發展出現轉折的關鍵行為 者。天津市成為低碳城市試點的路徑選擇，除了增益路徑依賴與路徑創造的 討論，亦提供城市治理與發展的新思維。

Whether a city’s economic growth depends more on upward development driven by local characteristics or downward request from a central government has been an important issue in the field of political economics. From the perspective of city development, pillar industries in a city should be related with the competitive advantage of a city, such as geopolitical location and industrial structure, so that the economy can grow fast. That is, the development of city economy is associated with the framework of path dependence. In the case of Tianjin, heavy industries have been the foundation of economic growth. The Tianjin Binhai New Area （TBNA）is no exception and becomes a strategic town of petrochemical industries. However, in 2010, Tianjin was selected as a low-carbon trial city by the central government and the Yujiapu CBD in TBNA was promoted as the first Low Carbon Model Town of APEC. This low-carbon development clashes with Tianjin’s industrial foundation. Specifically, Tianjin’s transformation to a low-carbon city means that it has to greatly change its industrial structure from high carbon consumption to green industries. Path creation explains the transformation route of city development in Binhai of Tianjin and emphasizes the role of the central government, both as a supervisor and a main driver, in the creation of a new path. Overall, the development of TBNA supplements the discussion of path creation and provides a new thinking for city development and governance.
