科技產業崛起已逐漸蠶食輕工業區原先土地利用制度安排，台北市內湖輕工業區自市地重劃完成後，經由行動者興建廠辦大樓形塑科技園區意象，供廠商違規使用，接著再由園區內廠商自發性成立「台北市內湖科技園區發展協會」與台北市政府定期召開座談會，並配合修正「台北市內湖輕工業區輔導管理辦法」共同治理園區內土地利用方向，締造科技產業經濟奇蹟，成為活化產業用地新典範，變更為名符其實「台北市內湖科技園區」。 然而，毗鄰地區大彎北段商業區、娛樂區行動者藉以放寬產業進駐內湖輕工業區為由，衝擊大彎北段商業機能，因而產生替代效果，陸續將商業用地及娛樂用地，興建住宅社區違規供住宅使用，截至今日該地區約已達3,000戶，實際使用狀況，與都市計畫呈現明顯不符，已造成商業區、娛樂區與住宅使用衍生嚴重互斥等現象。 本文將以「制度厚實」、「路徑依賴」、「公共利益」等相關理論分析案例，透過公、私部門專業人士進行深度訪談提供卓見，作為本文研究過程中相互辯證及立論參考依據，進一步釐清兩地區制度變遷分歧原因，加以探索大彎北段商業區、娛樂區供住宅使用之正當性，抑或回歸商業及娛樂使用，並將研究結論提出建議事項，落實產業用地「公共利益」之精神。 / The rise of technology industry has gradually eroded the arrangement of original land utilization. Therefore, the land of light industry was replotting in Neihu. The actors wanted the area to be Technology Park, so the buildings were used inappropriately for firms. The firms in park established an association spontaneously and named “Taipei Neihu technology park development association. “Taipei city hall made the regular meetings with the association and coordinated to revise the counseling regulations of Taipei Neihu light industry. Government and companies managed the direction of land's usage together and make the economic miracle of technology. Thus, it’s a model to activate industrial land. The land named “Taipei NeiHu Technology Park” However, according to this reason, the commercial function of Northern Dawan has been impacted. In order to find alternatives, the land of commercial and entertainment was supplied to residence use. As of today, it’s over 3,000 houses in the region. The actual situation of usage is not identical with the city plans, which causes mutual exclusion among the region of commercial, entertainment, and residences area. This study used those theories (for institutional thickness, path dependent and Public Interest) to analyze some cases. Through the deep interview by experts which come from public and private departments, they provide some advice as mutual dialectical reference; we will also clarify the reasons of rule discrepancy between two regions in order to further explore the legitimacy of the usage in Northern Dawan commercial area and entertainment area, or return to commercial and entertainment use. We’ll submit conclusions and bring suggestion to implement the spirit of public interest on industrial estate.
