网络外部性下我国企业技术引进策略

利用Hotelling模型所构建的多维产品差异化模型，深入研究了在具有产品网络外部性特征的行业中，我国政府和企业的优化技术引进策略，指出当国际可选择技术与我国自主研发技术质量差距较大时，技术引进国政府应鼓励本国企业引进尽可能高质量的技术；当国际可选择技术与我国自主研发技术质量差距较小时，我国政府应限制本国的技术引进活动；在推动本国企业技术引进活动时，技术引进国应权衡比较引进技术与原有技术的质量差距、技术之间兼容性、技术许可收费比例、技术引进的技术溢出强度等因素，并强调技术企业拥有新技术的知识产权.在此基础上，提出相应的政策建议.

The Optimal Import Strategy for Chinese Industries with Network Externality

Using the vertical differentiation model modified by Hotelling model,this paper analyzed the optimal import strategy for Chinese network externality industries.According to the analysis,some suggestions were given as below.Firstly,if the technological gap between the local technology and foreign ones is absolutely large,the government should prompt the local potential entrant to import the highest-quality foreign technology with low product compatibility.Secondly, if the technological gap between the local technology and foreign ones is absolutely small,to forbid the technology import is reasonable.Thirdly,the government should take some factors into account,such as quality gap,compatibility,charge rate of international licensing,and technology spillovers.Above all, some political proposals were given.
