摘要：
由於資訊科技與網路技術的發達，數位平臺的重要性與規模也不斷提高，就市場價值而言，許多數位平臺已經成為全球性和具有主導性的公司。近年來，全球主要國家的競爭主管機關紛紛提出對數位市場的相關見解，並就此類新興競爭議題擬訂相關的規範或政策。本研究從檢視我國消費者、廣告主、媒體代理商使用數位平臺（包括搜尋引擎、社群網路、影音平臺、App商店）的狀況，評估數位平臺在國內可能涉及的競爭議題，並建議主管機關在處理數位平臺涉及競爭疑慮時仍應以競爭法的精神為依歸，確保自由與公平競爭，以靈活應對新型態的競爭問題，因應方式可從短期策略與中長期策略分別加以思考，一方面維護產業發展環境的健全，另一方面兼顧促進經濟穩定提升消費者福祉。
The advancement of information technology and internet technology has continuously increased the importance and scale of digital platforms. In terms of market value, many digital platforms have become global and dominant companies. In recent years, competition authorities in major countries have put forward insights on the digital market, and formulated relevant regulations or policies on such emerging competition issues. This study examines the usage of digital platforms (including search engines platforms, social networks platforms, video platforms, and App stores) that is surveyed from Taiwan consumers, advertisers, and media agencies, and according the data to evaluates competition issues that digital platforms may be involved in Taiwan. We recommend the competition authorities should follow the spirit of competition law when dealing with competition concerns related to digital platforms, to ensure free and fair competition, and to flexibly respond to new types of competition issues. It is suggested that the response method can be considered separately from short-term strategies and medium- and long-term strategies to maintain the industrial development environment, promote the economic stability and prosperity and improve the well-being of consumers.
