    電子商務之所以能提高企業競爭力,是因為企業成本相對收縮和企業的邊界擴張競爭優勢,所謂企業成本相對收縮即邊際成本遞減,這種邊際成本遞減效應可以同時出現在生產成本、管理成本和交易成本三個領域中,電子商務通過提高勞生產率來降低生產成本,柔性製造技術的替代效應降低了庫存管理成本,與此同時,電子商務減少企業與消費者之間的環節,縮短路徑距而降低企業內外的交易成本,提高了企業產品和服務銷商改變供貨方式的交易成本,使之形成企業競爭的壁壘;所謂企業最優邊界的相對擴張,是指由於規模管理效應即電子商務運用信息技術使企業以低信息成本共享管理成本,使企業總體管理成本攤到各個管理環節和程中,企業規模擴大而邊際管理成本逐漸下降,相同的管理成本可用於管理更大規模的企業,即隨著電子商務在企業中的應用,企業的最優邊界相對擴張了。
