The support centers provide aid programs to solve problems faced by domestic urban small manufacturers due to the aging and structural vulnerabilities of the clusters. The purpose of this research is to categorize and analysis the spatial characteristics of ‘Urban Small Manufacturer Support Centers’. The spatial scope of the study includes small manufacturer ‘(Metropolitan) Specialized support centers’ and ‘Complex support centers’. Through a review of laws and business plans, I identified the programs and spaces of support centers. To categorize them, I classified into ‘Independent’ and ‘Integrated’ based on functional integration. Then, I examined spatial compositions using 6 support categories: ‘Planning’, ‘Education’, ‘R&D’, ‘Production’, ‘Exhibition·Sales’, and ‘Complex cultural’ spaces. I also analyzed placement forms which include ‘Entry’, ‘Linked’, ‘Distribution’, ‘Hub’, and ‘Complex’. Using the framework of functional integration and placement forms, I identified a total of 7 types through a comprehensive survey and analyzed their characteristics. Spatially, ‘Planning’ and ‘Education’ spaces appear in all types. ‘Production’, ‘R&D’ and ‘Exhibition·Sales’ spaces appear in ‘Integrated’. The increase of ‘Complex cultural’ spaces is a next spatial trend to enhance the competitiveness of small manufacturer through collaboration and networking. Depending on the year of opening, it was dominant in the order of 'Integrated/Distributed’ (shift from Independent/Entry), ‘Integrated/Hub’ every 3 years. Recently, there is a trend towards more ‘Integrated/Complex’ support centers. This study stands out for classifying categories for urban small manufacturer support centers from an architectural perspective, which has not been addressed in previous research. The significance of this research lies in its potential as foundational data for future improvement research.
