永續理念下工業區再發展策略評估之研究—以都市計畫工業區為例

根據內政部全國國土計畫(2018)產業用地規劃體系推估，於「2012年以前開發的產業用地完全利用」前提下，至2036年仍須多劃設3,311公頃以供產業發展使用。然而產業用地現況面臨區域供需失衡、低度利用且工業區老舊缺乏更新、整合等課題。面對產業用地之短缺，除規劃增設產業用地外，應回頭檢討現況未盡利用、閒置之工業土地、研議適當之活化策略，提高利用效率。本研究以都市計畫工業區為研究對象，基於永續發展目標(SDGs)為發展目標，將工業區再發展策略分為「繼續作為產業使用」、「作為產業專用區」、「作為住宅用地」、「作為公共設施用地」等四種方案。首先對都市計畫地區內不同工業區以「區位條件」、「產業群聚程度」進行樣態分類;評估準則則依據永續發展目標(SDGs)概念擬列生產、生活、生態等三個構面，共九項指標。透過層級分析法專家問卷及偏好順序結構法，分析不同樣態工業區再發展策略之優劣排序，並透過數個不同樣態進行個案分析。研究結果發現專家學者認為都市計畫工業區於再發展時，應優先採用「作為產業專用區」策略，並普遍認為作為住宅用地為較劣策略，對於產業群聚程度佳者，建議土地維持供產業活動使用，而產業群聚差者，作為公共設施用地為次優策略。本研究成果可供相關主管部門於工業區再發展策略之參考。

According to the estimation of the Industrial Land Planning System of The National Spatial Plan (2018), under the premise of "full utilization of industrial land developed before 2012", 3,311 hectares must still be allocated for industrial development by 2036. However, the current situation of industrial land is facing issues such as imbalance of regional supply and demand, low utilization, and lack of renewal and integration of old industrial areas. In order to address the shortage of industrial land, in addition to planning to increase industrial land, it is necessary to review the current unused and idle industrial land, and discuss appropriate activation strategies to improve utilization efficiency. This study takes industrial zone in urban plan area as the research object, and based on sustainable development goals (SDGs) as the development goals, the redevelopment strategies of industrial areas are formulated into four options: "Continued to be industrial development land use", "Restricted industrial district land use", "Residential land use.", and "Public facilities land use." First, classify the different industrial zones in the urban planning area according to the "location conditions" and "industrial clustering degree". The evaluation criteria are based on the concept of Sustainable Development Goals (SDGs) to draw up three dimensions: production, life, and ecology, with a total of nine indicators. Through analytic hierarchy process (AHP) experts' investigation method and PROMETHEE method, analyze the pros and cons of the redevelopment strategies of different types of industrial zones. Then select a few different industrial zones for case analysis. The results of the study found that experts and scholars suggest that urban planning industrial areas should prioritize the strategy of " Restricted industrial district land use." when redevelopment, and generally believe that " Residential land use." is the worst strategy. For industrial zones with good industrial clusters, it is recommended that the land be maintained for industrial activities, while for those with poor industrial clusters, "Public facilities land use." is the second best strategy. The results of this study can be used as a reference for the relevant authorities in the redevelopment strategy of the industrial zone.
