網際網路的興起，許多傳統的零售業者認為透過網路進行購物是另一種新興的管道。也由於科技的快速發達，網路成為商家另一個用來置放商品、以及提供消費者產品比較的購物環境。對於網際網路的出現，使消費者購物變的更有效率的研究，集中在交易效率的四個領域：產品價格水準、菜單成本、價格彈性，和產品價格離散程度。較少研究消費者網路訂購和產品交換，產生交易效率的機制。再者，研究網路購物交易效率都只集中在兩個階層—顧客和網路零售商，較少研究會去探討多階層的供應鏈，資訊和貨物交換所產生的交易效率，如何去完成顧客的線上訂購。本研究針對完成顧客線上訂購貨物的送達，評估供應鏈上交易效率的決策機制。
本研究的研究範圍是以書籍為產品類別，而以國內網路書店為研究主體。依照不同的經營型態，將網路書店分為三大類，選取四家網路書店作為研究對象。包括：博客來網路書店、金石堂網路書店、遠流博識網網路書店及聯經網路書店。本研究首先列出影響供應鏈交易效率的構面與評估項目。其次評估在不同的通路階層所發生的線上購物，供應鏈交易效率有何差異。最後建構模式，驗證與供應鏈交易效率有關的因素。

The emergence of the Internet may have fundamentally altered the mechanisms underlying information exchanges between sellers and end consumers. However, little attention has been given to the impact these mechanisms have on the efficiency of supply chain operations. This paper begins to address this deficiency in the literature by evaluating supply chain transaction efficiency effects from Internet purchases by consumers. It develops and empirically tests a theoretical framework examining the role Internet purchases have in establishing transaction-efficiency levels in product exchanges involving sellers, placed at different supply chain echelons, and consumers. The theoretical framework integrates the transaction-cost and internet economics, inter-organizational information systems, and supply chain management literatures.
This progression has been highlighted in previous research on Internet-facilitated consumer transactions. Up until now, the research has centered on four transaction efficiency areas: product-price levels, menu costs, price-elasticity levels, and product-price dispersion. Little is known about efficiency-generating decision-making mechanisms involved in product-exchange operations and transactions stemming from consumers' Internet purchases. Furthermore, studies on Internet transaction efficiency have exclusively concentrated on dyads spanning only consumers and Internet retailers. Little attention has been given to transaction efficiency in the exchange of information and goods across multiple dyads of supply chains supporting the fulfillment of online consumer orders.
