信息经济下的网络效应

The Network Effects Under Unformation Economy

首先以产品的外部性和信息性为准则对网络效应进行了重新界定,将信息性不足的外部正反馈效应定名为集聚效应;接着按照网络形态和用户联结方式的不同将网络效应划分为直接有形网络效应、间接有形网络效应和间接无形网络效应(硬/软件模式)3种,指出3种网络效应分别对应于信息内容产品(软件)和信息接收产品(硬件)均未商品化、软件商品化以及硬、软件商品化的情形,从而获得了信息经济意义上网络效应的统一分析框架;最后简要分析了网络效应的运行机制。

Rifstly,the concept of network effects is redefined under the externalities and information varieties,so some externalities effects just like as ATM network,car server network,and keyboard network are excluded from network effects,but named centralized effects.Then according the conformation of network,and the connection among consumer,network effects are classed there types,including direct visible network effects,indirect visible network effects,and indirect invisible network effects(hardware/software paradigm).Based on the separating of system product from compementary product in product combination,we found three kinds of network effects can be viewed as three situations in turn,which are hardware and sdftware all are not commercial,software is commercial.and hardware and software all are commercial.So we get a general analysis framework of network effects under information economy.At last,the rules of network effects are introduced briefly.
