社會企業將社會價值和企業利潤結合成新的營運模式，使能產生自主能力以解決社會需求的一種組織型態，它的發展型態對於社會正向發展有關鍵的影響力與重要性。此外，隨著網路媒體發展，社交平台已經成為專業社群重要的溝通或是發佈訊息的管道，社群媒體的文本承載了極其豐富的資訊。為了捕捉社會企業的發展動態，本研究選擇社群媒體中最大的微網誌社交媒體平台—推特之小短文為文本來源，以社會企業最重要的主題標籤為檢索條件，以 2018年6月到2019年9月為研究期間，透過Twitter API共計檢索232,786 條短文內容。進一步透過文字探勘技術中的主題模型建構隱含 Dirichlet 配置演算法，分析社會企業的內容主題、流行話題與近期趨勢發展。實證結果顯示社會企業議題主要可以分成三大主題（策略、影響力和商業模式）。對此，本文將其進一步開展成六項指標（社會價值、創業機會、環境變遷、企業經營、社會網絡、團隊成員），最終形成一個社會企業的概念框架，期有助於瞭解近期社會企業的討論重點，並進一步作為後續研究者延伸的參考方向。
Social media is a major channel for communication for professional and social groups. The texts on social media contain extremely rich information. To capture the development of social enterprises, this paper examines tweets on Twitter, the largest microblogging and social media in the world and searches the hashtags on the Twitter API most important to social enterprises. The Latent Dirichlet Allocation algorithms for topic modeling as a text mining technique are used to process the contents, topics and trends of these tweets. The results suggest that these tweets can be divided into three content groups (strategy, impact and business). This paper expands this into six indicators (social, opportunity, change, enterprise, network and team) and establishes a conceptual framework of social enterprises. The purpose is to understand the pertinent issues surrounding social enterprises recently and extract findings as a reference to follow-up studies.
