「2015 臺北設計城市展」以社會設計為主題，期望藉由探討社會設計重新鏈結臺北的設計動能與社會意識。本文首先追溯社會設計理論發展脈絡，釐清社會設計的定義。接著探討「2015 臺北設計城市展」活動是否扣合其預設的「賦權、幫助利他、社會整合」核心價值。研究發現：展覽強調對人的關切與社會整合，探究人與其情境脈絡的社會設計如何進行，強調民眾參與和增能，但是缺乏民眾參與的積極策略；展覽之後可持續性實踐的可能性則有待強化。對活動「海選!100 個社會設計提案」的議題內涵及服務對象分析，發現提案多為對問題局部的改善，少有根本性的變革之企圖，也鮮見跨領域的合作。最後建議政府應1.落實民眾參與的實踐；2.可持續性實踐的整全規劃；3.更重視改變人心策略的設計；4.促進跨領域的合作，以真正落實社會設計。
