　　幾十年來，製造業廠商運用多種資訊科技來改善公司績效。這些資訊系統不僅促進資訊在供應鏈夥伴間流通，也協助廠商完成存貨管理與物流規劃。特別的是，資訊系統強化了合作策略的發展，並且透過供應鏈的整合降低需求資訊傳遞的扭曲。本研究主要探討企業如何透過資訊整合降低長鞭效應的衝擊，並且進一步證明長鞭效應對公司績效的負面影響。資訊分享、通路整合、長鞭效應與公司績效為本研究的四個分析構面。我們首先發展研究架構並探討研究構面間之關聯性，接著利用個案研究比較企業實務與學術理論的差異。從文獻回顧和個案研究的結果，我們設計出正式問卷來進行後續量化的分析。研究結果發現資訊分享對於通路整合與公司績效有正面的影響，企業可以透過降低長鞭效應來改善經營績效。最後我們提出本研究的發現，探討不同的設定對於供應鏈合作是否有效益上的影響。

　　Over the past decade, manufacturing firms have implemented multiple types of information technology to improve their performance. These information systems fa-cilitate the information flow among supply chain members and contribute to inventory management and logistics planning. Specifically, these systems support coordination strategies aimed at strengthening inter-organizational cooperation and reducing distor-tions in the exchange of demand information. This research investigates how informa-tion integration assists enterprises to counter the bullwhip effect and further verify the damaging influence that bullwhip effect could have on a firm’s performance. Informa-tion sharing, channel collaboration, bullwhip effect, and firm performance are four research constructs analyzed in our study. We initially develop a research framework and describe the relationships between the research constructs. An in-depth case stud-ies method is then used to explore the differences between theory and practice. From a review of the literature and the case study results, we evolve a formal questionnaire which is then used for quantitative analysis. The results are consistent with a positive impact of information sharing on channel collaboration and the improvement in com-pany performance by diminishing the negative impact of the bullwhip effect. Finally, we draw on the findings of this study to discuss different supply chain settings which would influence the effectiveness of supply chain collaboration.
