网络效应指产品的用户数量以及互补品数量会影响到产品价值的现象。网络效应产品进入市场时，初期的用户规模和互补品规模都会对新产品推广形成制约。目前，我国新能源汽车推广缓慢，但无论学术研究还是政策补贴都缺少对网络效应机制的思考。本文通过对当前市场中消费购买意愿的调研，证实了新能源汽车的购买选择与用户基础、互补品提供之间确实存在着所预期的直接、间接及局部网络效应。从而也表明在新能源汽车推广的导入期，优先发展互补品网络的重要性。最后本文探讨了如何克服网络效应制约的策略以及政府在其发展中可以发挥的作用。%〔Abstract〕 Network effects exist when a customer's utility for a product increases as the number of users , complementary products or services increases . Which means the adoption of network effects product are complex , and it will be both constrained by the installed base and complements scale . Although alternative fuel vehicles (AFV ) experience a slow development in our country , a thorough understand-ing of the network effects of AFVs exists neither in academic research nor in administration policies . Our research demonstrates the exis-tence of direct , indirect and local network effect of AFV , through site investigation and analysis of consumers purchase intention . The sur-vey results further indicates the importance of giving priority to the development of AFV's complements network . At the end of the paper , we discuss strategies about how to overcome the barriers created by network effects and the role of government in AFV's development .
