現今許多企業雖明白企業間資訊分享對供應鏈所帶來的好處，然而有些企業對於資訊分享的行為卻仍遲遲不見動作，依然存在著許多疑慮，到底是什麼原因讓他們停滯不前呢？製造商與客戶分別為獨立的經濟主體，在自我利益考量下，一定存有差異性與衝突性，任何掌握特定資訊者均享有資訊不對稱的優勢。製造商應透過具吸引力的交易行為及交易條件，塑造良性的交易環境以及分享的重要的資訊以拉攏客戶。
本研究以代理理論（Agency Theory）為核心的觀點再加上企業間的共同願景（shared vision），建構出一個研究模型用以研究影響企業間資訊分享行為的因素。本研究採用問卷調查法蒐集資料，問卷郵寄對象為天下雜誌1000大公司，設定受訪對象為公司的業務或採購部門的成員，並以結構方程模式（Structure Equation Model, SEM）進行資料分析，研究結果顯示感知不確定性（perceived uncertainty）受感知資訊不對稱（information asymmetry）及資訊安全考量（information security concerns）因素的影響，進而影響其對於資訊分享意願；共同願景也會增加資訊分享的意圖，進而促使企業間資訊分享的行為。

Under the self-benefit consideration, the manufacturer and the customers have different business goals, which usually promote conflicts. Since information owners have superiority, manufacturers try to create a better atmosphere for doing businesses such as sharing critical information with customers.
We integrate agency theory and shared vision to construct a model to study the impact factors on information sharing behaviors between enterprises. A self-administered questionnaire method was adopted to collect data and structure equation model (SEM) was employed to analyze the data. The results indicate that enterprises’ perceptions of information asymmetry and information security concerns significantly increase their perceptions of uncertainty and further impact their intentions of information sharing. Moreover, shared vision between enterprises significantly increases their intention to share information and, thus, promote their actions to share information.
