未登記工廠群聚地區合法化依照《工廠管理輔導法》可優先採新訂都市計畫或開發產業園區規劃處理，以銜接國土計畫劃為城鄉發展地區，然《群聚地區認定原則》僅以空間使用比例作為群聚之認定，目前實務上仍需有更多劃設群聚地區與進行合法化之討論。本研究為劃設具有群聚意義之群聚地區與釐清群聚地區合法化之條件，嘗試以產業、廠商及空間群聚觀點辨識具有群聚之空間，並探討合法化可行性以銜接至國土功能分區城鄉發展地區第二之三類劃設。
本研究以嘉義縣未登記工廠與合法工廠為分析資料，結合空間關係與生產關係為研究架構，提出群聚地區劃設方法與合法化評估架構。群聚地區辨識與劃設部分以產業群聚為理論基礎，透過區域空間自相關方法辨識群聚熱點，指認出具有空間關係與生產關係之群聚地區；群聚地區合法化評估以文獻和法規回顧結果提出「土地屬性」、「聚集經濟」和「交通區位」三大類別指標，以層級分析法(AHP法)獲取指標權重，以理想解相似度順序偏好法(TOPSIS法)計算群聚地區可行性分數，求得合法化可行性最高之區域。
本研究將群聚地區分為四種類型，評估結果以納入正式部門且同時具有空間關係與生產關係之群聚類型三為最適宜合法化之類型；其次為納入正式部門具有空間關係之群聚類型一，顯示以群聚觀點納入正式部門和結合生產關係之重要性。因此，群聚地區應從地區產業發展進行整體考量，提出劃設群聚地區應考量生產關係、工廠家數和臨近區位等原則，作為未來立法單位及空間規劃單位之參考。

This study discusses the identification and legalization evaluation of clusters of unregistered factories, proposes a clustering method and a legalization assessment framework, and identifies clusters with spatial and production relationships; evaluates the areas with the highest legalization feasibility based on literature and regulatory review indicators.
The purpose of this study is to explore whether the existing agglomeration area types recognized by the principle of standardization of space use ratio have economic and industrial significance in industrial agglomeration. This study takes the "Agglomeration Area Identification Principles" as the basic threshold for cluster identification, and further combines the space and production relations of industrial clusters to identify agglomeration areas. In order to make the identified agglomeration areas feasible at the legal level, incorporate the indicators of relevant laws and regulations, explore the feasibility of legalization, and finally establish a set of framework and principles.
The research results divide agglomeration areas into four types, among which agglomeration type 3 is the most suitable type for legalization; followed by agglomeration type 1, which shows the importance of incorporating formal departments and combining production relations from the perspective of agglomeration. This study believes that agglomeration areas should be considered from the perspective of regional industrial development, and proposes that the designation of agglomeration areas should consider the principles of production relations, the number of factories, and adjacent locations, as a reference for future legislative units and spatial planning units.
