本研究探討在現代資訊多元化的環境中，資訊來源之信任與資訊品質對購買傾向的影響力，同時試圖研究消費者之涉入程度是否會在資訊來源信任與資訊品質對購買傾向的影響產生調節作用。 本研究採用相關分析及迴歸分析驗證變數間的相關性，並透過階層迴歸分析驗證涉入程度的調節效果。本研究有三項主要發現：（1）對資訊來源信任會正向影響消費者的購買傾向；（2）資訊品質會正向影響消費者的購買傾向；（3）當資訊來源為網路來源或行銷控制來源時，涉入在資訊來源信任對消費者購買傾向的影響中有正向的調節效果，而在資訊品質對消費者購買傾向的影響中有負向的調節效果。;This research is focusing on how the consumers will trust the information and how good the quality of information is from various information sources buying the smartphone product in this modern, fast-developed society. We would like to know how they will impact on the purchasing intentions. Simultaneously, we also try to analyze whether the levels of involvement has moderating effects among the trust in information ,the quality of information, and consumers’ purchasing intentions.
