【摘要】：企業(yè)價(jià)值網(wǎng)絡(luò)成為互聯(lián)網(wǎng)時(shí)代新的競(jìng)爭(zhēng)團(tuán)體,其價(jià)值網(wǎng)絡(luò)穩(wěn)定性問題備受關(guān)注。為定量分析企業(yè)價(jià)值網(wǎng)絡(luò)穩(wěn)定性,維持其高效、穩(wěn)定運(yùn)行狀態(tài),提出一種無向加權(quán)節(jié)點(diǎn)收縮法(undirected weighted node contraction method,UWNC)量化分析其穩(wěn)定性。分析企業(yè)價(jià)值網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu),通過節(jié)點(diǎn)收縮法從空間結(jié)構(gòu)角度計(jì)算各節(jié)點(diǎn)重要度;量化各節(jié)點(diǎn)在網(wǎng)絡(luò)中相互關(guān)系強(qiáng)度,充分考慮關(guān)系中的業(yè)務(wù)關(guān)系強(qiáng)度和社會(huì)關(guān)系強(qiáng)度兩部分內(nèi)容,通過二者加權(quán)計(jì)算各節(jié)點(diǎn)在網(wǎng)絡(luò)中的關(guān)系強(qiáng)度,并以此作為整個(gè)價(jià)值網(wǎng)絡(luò)重要度的權(quán)重值;綜合上述方法,形成加權(quán)改進(jìn)的企業(yè)價(jià)值網(wǎng)絡(luò)穩(wěn)定性分析模型,模型客觀考慮了各節(jié)點(diǎn)在網(wǎng)絡(luò)中的物理位置及相互影響關(guān)系,計(jì)算結(jié)果可以較好反映客觀實(shí)際。最后通過案例研究驗(yàn)證模型的有效性。
[Abstract]:Enterprise value network has become a new competitive group in the Internet era, and the stability of its value network has attracted much attention.In order to quantitatively analyze the stability of enterprise value network and maintain its high efficiency and stable running state, an undirected weighted node contraction method (UWNCC) is proposed to quantitatively analyze its stability.The topological structure of enterprise value network is analyzed, the importance of each node is calculated from the angle of spatial structure by the method of node contraction, and the relationship between each node in the network is quantified.Considering the business relationship strength and the social relationship strength in the relationship, the relationship strength of each node in the network is calculated by the two weighted methods, which is regarded as the weight value of the whole value network importance degree.A weighted and improved stability analysis model of enterprise value network is formed. The model objectively considers the physical position of each node in the network and the mutual influence relationship. The calculation results can well reflect the objective reality.Finally, the validity of the model is verified by case study.
