台灣網際網路使用人口持續增加，據資策會ECRC-FIND研究群所作的調查截至2003年3月底已達867萬人，其中寬頻用戶達226萬戶，較2002年第四季增加17萬戶，成長率達8%。據IDC的調查報告指出，由於全球網路使用人口快速成長，預估在2005 年將達到十億人，約佔全球總人口的15％，屆時全球電子商務交易金額，也可望從2000 年的3540 億 美元，以70％的複合年成長率增長至5 兆美元。 同時台灣的電子商務市場也因網際網路的普及而快速成長，據資策會估計台灣B2C 線上交易金額將高達新台幣261.5億元，較2002年的157.5億元成長66%，隨著電子商務的成長，各式各樣的線上購物網站相繼成立，而B2C ASP業者提供中小企業一個快速而且易學好用的B2C網路開店平台，讓中小企業可以趕上在線上購物賺錢的熱潮。 台灣的B2C ASP採取不同的經營模式來服務中小企業，本研究在探討台灣B2C ASP的經營模式，我們採用個案訪談及資料收集方式來分析歸納各個B2C ASP 的經營模式，製作B2C ASP業者概況、提供服務功能及價格列表，並對金流服務、物流服務廠商作概要說明，同時比較ICP、ISP及入口網站經營電子商務模式，並且探討中小企業選擇B2C ASP廠商的考量因素，期望對業者及中小企業選擇B2C ASP 廠商有所助益。 / The number of the Internet usage has been increased rapidly these years in Taiwan. According to a survey report of ECRC-FIND research group of III (Institute of Information Industry), in the end of the first quarter of 2003, the number of the on line users in Taiwan had been up to 8.67 millions, including 2.26 millions users using broadband to link to the Internet and the number of broadband users had been increased by 8% compared with the statistics of last quarter. Moreover, a survey report from IDC (International Data Corp.) estimates that the Internet population will be up to one billion worldwide in 2005, which will be 15 % share of total world population. Meanwhile, the total revenue of EC (Electronic Commerce) will increase from US$ 354 billions in year 2000 to US$ 5,000 billions in 2005. In the meantime, the EC market has also been growing very fast because of the rapid growth of Internet usage in Taiwan. A study report of III (September 2002) shows that the revenue of on-line shopping will be increased by 66% from NT$15.75 billions in year 2002 to NT$26.5 billions in 2003, Therefore many on-line stores run business one by one under this hotter and hotter on-line business environment while B2C ASP offers an easy and fast way to open an on-store on the Net. There are many studies on ASP research recently, but only few studies focus on B2C ASP. We found that different B2C ASP offer different kind of business model to help their clients who are mostly the SME (small medium enterprises) in Taiwan. This thesis focuses on studying the business model of B2C ASP in Taiwan to learn how they are doing business via CASE STUDY Method by interviewing venders and collecting their secondary information from newspapers, magazines, brochures, web-sites and so on. Then we also describe their co-operation and system integration with Internet cash flow process venders, forwarders and their business partners like Portal and ISP to know how they meet with their clients’ requirements. We also study and analyze the criteria of SMEs to select a B2C ASP, and hope this information will be helpful to the SMEs. In the last we also make recommendations to the venders and the authorities in charge.
