2、隨產(chǎn)品差異化程度減弱均呈現(xiàn)U型變化,上游廠商傾向于選擇生產(chǎn)互補(bǔ)產(chǎn)品以提高企業(yè)利潤(rùn);對(duì)消費(fèi)者效用的影響則表現(xiàn)為:不存在買(mǎi)方抗衡勢(shì)力的情況下,消費(fèi)者的效用水平隨著產(chǎn)品差異化程度減弱呈現(xiàn)非線性變化,并且在產(chǎn)品不完全替代時(shí)達(dá)到最大;存在買(mǎi)方抗衡勢(shì)力的情況下,當(dāng)生產(chǎn)替代性產(chǎn)品時(shí),消費(fèi)者的效用水平隨買(mǎi)方抗衡勢(shì)力增加而上升;當(dāng)生產(chǎn)互補(bǔ)性產(chǎn)品時(shí),消費(fèi)者效用水平隨買(mǎi)方抗衡勢(shì)力的增加而下降。關(guān)鍵詞:管理科學(xué);競(jìng)爭(zhēng)策略;討價(jià)還價(jià)模型;買(mǎi)方抗衡勢(shì)力;產(chǎn)品差異化中圖分類(lèi)號(hào):C931.1 文章標(biāo)識(shí)碼:A文章編號(hào):100
