61、;p>　　過去十年里，互聯(lián)網(wǎng)使用出現(xiàn)前所未有的增長，這一現(xiàn)象已許多人被看作在虛擬環(huán)境中通過經(jīng)營獲利的機(jī)會之一。1993年1月份只不過出現(xiàn)了50個網(wǎng)站，而如今萬維網(wǎng)上卻已有160多萬個正在營業(yè)的商業(yè)網(wǎng)站（(Hoffman和Novak，2000年）。Lui,Jamieson在B2C電子商務(wù)中通過技術(shù)接受模型整合信任維度和風(fēng)險(xiǎn)認(rèn)知，不論企業(yè)對消費(fèi)者的電子商務(wù)（B2C電子商務(wù)）提供的利潤多大，這一經(jīng)營方式的發(fā)展預(yù)期多高，許多客戶仍然傾向于

62、選擇使用現(xiàn)有的線下分銷渠道。例如，2001年9月澳大利亞有410萬人注冊為網(wǎng)上銀行客戶，然而其中超過50%的并非活躍用戶（Kavanagh，2002年）。為了提高人們對B2C電子商務(wù)的使用，我們有必要確定影響其成長和發(fā)展的決定因素。針對B2C電子商務(wù)系統(tǒng)采納的研究能夠歸為技術(shù)接受研究的子范疇，因此，Davis（1986）所提出的技術(shù)接受模型（TAM）可用來解釋這一現(xiàn)象。近年來，技術(shù)接受模型早已被用于解釋萬維網(wǎng)的使用（Moon和Kim，2

63、001年）和B2C電子商務(wù)的運(yùn)用（Pavlou， 2001年）。目前來看，為了讓更多人采用 B2C電子商務(wù)，本研究通過混合、吸收多維度信</p><p><b>　　2. 理論發(fā)展</b></p><p>　　圖1顯示了研究中提出的模型。以技術(shù)接受模型為出發(fā)點(diǎn)，研究認(rèn)為概念化模型應(yīng)包含一些額外的理論構(gòu)想，其范圍可以從用戶認(rèn)知風(fēng)險(xiǎn)跨越到不同程度的信任。在這一節(jié)中，我們將

64、為模型構(gòu)想下定義并解釋其中包含的理論基礎(chǔ)。</p><p><b>　　2.1 交易意圖</b></p><p>　　在技術(shù)接受模型中，個人使用系統(tǒng)的意向被認(rèn)為是實(shí)際使用的前因（Venkatesh和Davis，2000年）。理性行為理論（TRA）證明了這一說法并加以闡釋。它宣稱，個體表現(xiàn)某一指定行為是由他或她想要表達(dá)行為的行為意向決定的（Fishbein和Ajzen，

65、1975年）。由于網(wǎng)上交易過程的性質(zhì)，其中包括使用網(wǎng)站進(jìn)行信息查詢，并使用網(wǎng)站進(jìn)行購買，正如技術(shù)接受模型提出的那樣，“使用意向”構(gòu)想可能還無法充分描述消費(fèi)者的行為。根據(jù)Pavlou（2001年）對其的定義，對B2C電子商務(wù)系統(tǒng)的“交易意向”是這一模型中的因變量。這個概念把原有的“使用意向”設(shè)想置于B2C電子商務(wù)背景下，并被定義為消費(fèi)者在B2C電子商務(wù)活動中實(shí)現(xiàn)任何與服務(wù)提供商進(jìn)行價(jià)值交換的意向。</p><p>

69、使用的積極方面，即有用性和易用性，卻極少關(guān)注使用過后的直接損失。這大大削弱了技術(shù)接受模型的解釋力度，在這種環(huán)境中用戶通過使用系統(tǒng)認(rèn)知風(fēng)險(xiǎn)，尤其是在B2C電子商務(wù)中，因使用造成的潛在損失被認(rèn)為是值得關(guān)注的一大問題。因此，我們作出以下提議：</p><p>　　H4：與B2C電子商務(wù)系統(tǒng)進(jìn)行交易的認(rèn)知風(fēng)險(xiǎn)與打算同這一系統(tǒng)實(shí)行交易的意向成負(fù)相關(guān)。</p><p><b>　　2.4&
