运用复杂网络方法开发了一个局部网络效应模型,主体采用新产品的效用包括取决于产品质量的内在价值和取决于产品在局部网络中流行程度的网络价值.结果表明新产品存在一个临界内在价值,低于该值时新产品扩散失败;高于该值时新产品扩散成功.初始阶段的安装基础不是决定扩散成功与否的关键,而是修正了临界内在价值的大小,而且这种作用很有限.此外,网络效应强度也是影响临界内在价值的重要因素.这些结论有助于企业制定有效的网络效应新产品战略.
A network model of partial network is developed by using complex network method.The main utility of the new product includes the intrinsic value depending on the product quality and the network value which depends on the prevalence of the product in the local network.The results show that the new product has a critical intrinsic value, Below this value the new product fails to spread; above this value the new product spreads successfully. The initial installation base is not the key to determining the success of the diffusion, but rather modifies the critical intrinsic value, and this effect is limited In addition, the strength of network effect is also an important factor that affects the intrinsic value of criticality, and these conclusions help enterprises to formulate effective new strategies for network effects.
