在數位轉型、人工智慧（Artificial Intelligence, AI）、雲端服務、資訊安全與金融科技快速發展的背景下，資訊服務業已成為企業數位化與營運升級的重要支援產業。由於資訊服務業具有知識密集、人才密集與高度客製化等特性，其核心資產多為技術能力、專業人才、產品模組、客戶關係與產業知識，企業若僅依賴有機成長，往往難以快速取得新技術、新市場與新客戶。因此，併購、策略投資與控股逐漸成為資訊服務業者取得外部資源、擴大服務範疇與提升競爭力的重要策略工具。
本研究旨在探討台灣資訊服務業者如何透過併購、策略投資或控股取得外部資源，並分析不同併購路徑對併後整合與綜效創造之影響。研究以精誠資訊與普鴻資訊為主要個案，分別代表大型資訊服務集團之「橫向生態型」併購模式與利基型金融資訊服務業者之「縱向深耕型」投資模式，並參照大聯大控股「前端分治、後台整合」之產業控股邏輯，探討其對資訊服務業平台化治理之啟示。
本研究採用質性個案研究法，輔以財務指標與公開資料分析。資料來源包括公司年報、財務報表、公開資訊觀測站、公司官方新聞稿、法人說明會資料、產業研究報告與相關學術文獻。研究並以營收成長率、毛利率、營業利益率、人均產值及人均營業利益等指標，作為觀察併購綜效之輔助依據，同時分析產品延伸、交叉銷售、資源共享與平台化管理等管理綜效。
研究發現，精誠資訊之併購策略較偏向橫向生態型擴張，透過金融科技、企業資訊系統整合、雲端、資安、資料應用與海外服務等布局，擴大集團服務範疇並建構一站式資訊服務生態系；其綜效主要表現在營收規模擴大、服務版圖延伸與集團平台化能力提升。相較之下，普鴻資訊之投資策略較偏向縱向深耕型併購／控制性股權投資，係透過投資捷智商訊補強金融監理科技、法遵管理與洗錢防制等專業能力，深化金融垂直市場並提升產品化與高附加價值服務比重；其綜效較可能反映於毛利率、營業利益率與人均獲利能力之改善。
本研究進一步指出，資訊服務業併購後之關鍵不在於單純完成股權取得或財務併表，而在於能否透過併後整合將外部取得之人才、技術、產品與客戶關係轉化為集團整體能力。參照大聯大控股之產業控股模式，本文建議台灣資訊服務業者可發展「前端專業保留、中台技術共享、後台行政賦能」之平台控股模式，在保留子公司專業彈性與客戶關係的同時，透過共享技術中台、集團治理與後台資源整合，提升併購後之財務綜效與管理綜效。

Against the background of digital transformation, artificial intelligence (AI), cloud services, information security, and financial technology, the IT service industry has become an important enabler of enterprise digitalization and operational upgrading. As this industry is knowledge-intensive, talent-intensive, and highly customized, its core assets are often embedded in technological capabilities, professional talent, product modules, customer relationships, and industry knowledge. Therefore, mergers and acquisitions, strategic investments, and controlling equity investments have become important tools for information service providers to acquire external resources and enhance competitiveness.
This study examines how Taiwanese information service companies acquire external resources through mergers and acquisitions, strategic investments, or controlling equity investments, and how different acquisition paths influence post-merger integration and synergy creation. A qualitative case study approach is adopted, with SYSTEX Corporation and Provision Information Corporation selected as the main cases. SYSTEX represents a large information service group adopting a horizontal ecosystem-oriented M&A model, while Provision Information Corporation represents a niche financial information service provider adopting a vertical deepening M&A model through its controlling equity investment in MetaEdge Corporation. This study also refers to WPG Holdings’ “front-end decentralization and back-end integration” model to explore its implications for platform holding in the IT service industry.
The findings show that SYSTEX’s M&A strategy focuses on horizontal expansion through financial technology, enterprise information system integration, cloud services, information security, data applications, and overseas services. Its synergies are mainly reflected in revenue scale expansion, service coverage extension, and group-level platform capabilities. In contrast, Provision Information Corporation’s vertical deepening M&A strategy, through its controlling equity investment in MetaEdge Corporation, strengthens regulatory technology, compliance management, and anti-money laundering capabilities. Its synergies are more likely to be reflected in improvements in gross margin, operating profit margin, and operating profit per employee.
This study argues that the key to M&A success in the IT service industry lies not merely in equity acquisition or financial consolidation, but in transforming externally acquired talent, technologies, products, and customer relationships into organizational capabilities through post-merger integration. Based on WPG Holdings’ industrial holding model, this study proposes a platform-based governance framework characterized by front-end professional autonomy, middle-platform technology sharing, and back-end administrative empowerment.
