不同於以往多以文字作為訊息傳遞的社交網站，主張以圖像及影音呈現、互動的社交平台Instagram，推出後成長率迅速提升，增長幅度超越Facebook，透過濾鏡（Filter）模式，讓使用者自行編修圖像為最大特色，而主題標籤（Hashtag）的使用則豐富個人資訊管理與分享上的需求，吸引用戶使用。

　　本研究根據Instagram平台的特質，以及新媒體的使用動機，分為「自我呈現」、「資訊尋求」、「記錄生活」、「社交互動」、「休閒娛樂」、「追求流行」等動機面向，分別探討使用者在「展現自我」、「資訊獲得」、「紀錄回憶」、「社交資本」、「娛樂放鬆」以及「跟上潮流」獲得的使用滿足感，同時並針對Instagram平台最具特色之主題標籤和照片編修功能，進一步探討其可能的影響。

研究結果發現，超過一半以上的使用者天天使用Instagram，其中又以女性居多，年齡多集中在15到24歲，使用動機層面以記錄生活動機對Instagram紀錄回憶的滿足影響最為強烈；另一方面，使用者的追求流行動機對Instagram使用程度上之正向影響最為強烈；而使用程度愈頻繁則愈容易達到展現自我的滿足。此外，主題標籤的使用程度對使用滿足各構面皆有顯著正向影響，其中以跟上潮流的滿足最為明顯；而照片編修（濾鏡的使用）程度卻僅只對跟上潮流的滿足有顯著正向影響。

Unlike the previous social networking sites that have been written as messages, it advocates the Instagram of interactive social platforms with images and video. Its growth rate increased rapidly after its launch, surpassing Facebook. The filter mode allows users to make their own image editing. However, the use of hashtag enriches the need for personal information management and sharing to attract users.

This study is based on the characteristics of Instagram and the use motivation of new media. Divided into Self presentation, Information seeking, Record life, Social interaction, Leisure and entertainment, Pursuit of popularity. To explore the user's sense of satisfaction in the aspect of Self-expression, Information obtained, Record memories, Social capital, Entertainment Relaxation, Keep up with trends. At the same time for the Instagram platform, the most characteristic hashtag and filter function, further explore the possible impact.

The study found that more than half of the users use Instagram every day. The majority of users are women, aged between 15 and 24. The use of motivation, to record the life motivation of the Instagram record memories is the most powerful impact. On the other hand, Pursuit of popularity motivation has the strongest influence on the Instagram use intensity. The more frequent of use intensity, the more easily to achieve the satisfaction of Self-expression. In addition, the use intensity of hashtag has a significant positive effect on use satisfaction. Among of them, to keep up with the trend is the most obvious satisfaction. The use of the filter is only to keep up with the trends of satisfaction, has a significant positive impact.
