| Abstract: | This paper analyses quantitatively the development of electronic commerce with the Markov-switching model in the form of heteroskedasticity and fourth-order autoregression based on the Inter@ctive Week Internet Index(IIX) developed by the American Stock Exchange.The development of electronic commerce is summarized and its internal rules are discovered.It has been shown that electronic commerce is,at present,at a stage of transition from decline to revival. |
