很多学者对网络经济学中网络效应的作用机制存在不同的认识，这些认识表现在不同的经济模型中，本质上反映了这些学者对于网络的认识上的差异。网络是由位于节点上的用户构成的，这些用户通过使用相兼容的产品连接在一起。根据用户的不同连接方式，网络可以分为直接网络、间接网络与双边网络。直接网络效应理论强调了用户预期、过度惰性与过度动力以及安装基础等问题；间接网络效应理论强调了用户偏好多样化、互补品作用、一体化等问题；双边网络效应理论强调了用户需求相互依存性、小鸡与鸡蛋、单宿与多宿等问题。三种理论对网络效应的作用机制提供了不同的解释，它们之间既有区别又有联系，现实世界中的很多网络往往同时存在多种网络效应。

For a long time, there are different understandings among different scholars on the interaction mechanisms of network effects. This article thinks that these differences reflect their different understandings to the concept of network essentially. Theories of direct network effects investigate the direct network, theories of indirect network effects investigate the indirect network and theories of two - sided network effects investigate the two - sided network. Theories of direct network effects emphasize the questions such as users＇ expectations, excess inertia, excess momentum and installed base; Theories of indirect network effects emphasize the questions such as users＇ preference for variety, role of complements,integration ; Theories of two - sided network effects emphasize the questions such as interdependence of users＇ demand, chickens and eggs, single - homing and multi - homing. The three theories put different interpretations on the microscopic mechanism of network effects. However, these theories mean essentially some methods of modeling. Maybe in reality there exist multiple network effects in specific network.
