本研究在中國大陸調查訪問了23 家筆 記型電腦的相關廠商，包括4 家晶牌商， 分別是難蘭、惠菁、IBM 及聯想:5 家為晶 牌商供貨的ODM 製造商; 12 家零件供應 商: 1 家物流運輸商。另外，本研究還選取 了1 家處B全國外的零件供應商做為對比研 究之用。研究發現，在晶牌商與ODM 製造 商之間，人際關係在供眉鐘資訊管理中， 只有輔佐地位;然而，在ODM 製造商與零 件供應聞之闡，人際關係在供應鐘管理 上，則具有舉足輕重的地位。 本論文從三個角度分析中團大陸本土 企業在供應鏈資訊管理中所遇到的現象， 分別是社會環境、資訊類型與市場地位， 討論它們對供應譴責訊官理的影響。在供 應鏈資訊共用的決策中，市場地位與企業 經濟動機也是影響資訊共用的考慮因素之 一。供應鐘中企業的經濟動機未必一致: 大型企業往往希望資訊化，希望藉此加強 對供闡鏈的控制與國調，而中小型企業 (往往是上游製造商與供應商)在面面競 爭與價格壓力的情況下可能不願共用資訊。因此，全面賣訊化網路建設對民制度環境、硬體及人力建設等尚不健全的企業也許並不適用，因為在這些情況下，人際與社會網絡可以有效地保誼企業靈活快速應對市場變化。

This research surveyed 23 firms in the notebook industry in China, including 5 ODM suppliers for brand companies, 12 component suppliers, one logistic shipping company and one foreign supplier company. Four brand companies, Dell, UP, IBM and Lenovo were also included. The research finds that Quanxi plays axoxiliary role between brand companies and ODM suppliers. However, Quanxi has a significant role in the supply chains between ODM suppliers and components suppliers. This article analyzes supply chain management in Chinese firms from three perspectives, namely, social environments, information type, and market position. In supply chain management，a firm’s market position and economic incentives affect information sharing decision. Economic incentives of firms in supply chains are not necessary compatible. Larger firms have stronger incentive to design a better infor-mation system in order to control and coordinate suppliers. Small and medium-sized firms, usually upstream manufacturers and suppliers, might not want to share information due to competitive pressure and price competition. A perfect information network might not be desirable when institution environment, infrastructure, and human resources are not in place. Under such condition，or social networks can make firm more flexible in facing market changes.
