Use of time sequence method to predict the future growth trend of the fixed network telecom industry revenue ; contrasting the fixed telephone development of town and village , adopting logistic growth curve econometrics method to analyze three development stages of chinese village fixed telephone market ; draw a conclusion that the chinese village fixed telephone has a huge development potential ; and predict the development trend of village fixed network telecom in several years ; adopting logistic growth curve method to calculate and analyze internet business growth stage ; while studying internet development potential , we draw a conclusion that internet business also have a good growth foreground , and give a quantitative predict of internet industry development 運(yùn)用時(shí)間序列外推法預(yù)測(cè)未來(lái)固網(wǎng)電信業(yè)收入增長(zhǎng)趨勢(shì);通過(guò)城鎮(zhèn)與農(nóng)村固定電話(huà)發(fā)展對(duì)比,采用logistic成長(zhǎng)曲線(xiàn)計(jì)量經(jīng)濟(jì)方法分析了中國(guó)農(nóng)村固定電話(huà)市場(chǎng)發(fā)展的三個(gè)階段,認(rèn)為中國(guó)農(nóng)村固定電話(huà)處于高速發(fā)展的中期,具很大的發(fā)展?jié)摿?并定量預(yù)測(cè)出未來(lái)中國(guó)農(nóng)村固話(huà)發(fā)展趨勢(shì);在研究互聯(lián)網(wǎng)及寬帶接入業(yè)務(wù)發(fā)展?jié)摿r(shí),同樣采用logistic成長(zhǎng)曲線(xiàn)計(jì)量方法,分析了互聯(lián)網(wǎng)業(yè)務(wù)成長(zhǎng)階段,得出互聯(lián)網(wǎng)業(yè)務(wù)尤其是寬帶業(yè)務(wù)具有很好的增長(zhǎng)前景的結(jié)論,并定量預(yù)測(cè)出未來(lái)互聯(lián)網(wǎng)業(yè)務(wù)、寬帶業(yè)務(wù)的增長(zhǎng)趨勢(shì)。
By building up tumor growth aerodynamic model , when tumor growth aerodynamic laws is research to find : the process of tunor increasing squares with economic growth of gompertz growth parabola description ; we further study that gompertz growth parabola squares with population growth and regulation of logistic growth parabola description 摘要通過(guò)建立腫瘤增長(zhǎng)動(dòng)力學(xué)模型,研究腫瘤增長(zhǎng)動(dòng)態(tài)規(guī)律時(shí)發(fā)現(xiàn):腫瘤增長(zhǎng)的全過(guò)程與龔珀茲增長(zhǎng)曲線(xiàn)描述的經(jīng)濟(jì)增長(zhǎng)過(guò)程完全相符;進(jìn)一步給出了龔珀茲增長(zhǎng)曲線(xiàn)與描述種群的增長(zhǎng)與調(diào)節(jié)的邏輯斯蒂增長(zhǎng)曲線(xiàn)完全相似。
