摘要：近年来，在电子信息、网络通讯等高技术领域，私有协议发展成为重要的标准形式，正深刻改变着国际标准化的格局。以思科系统公司的私有协议为切入点，研究了私有协议的生成机制。研究表明，私有协议缓解了标准滞后与技术发展的矛盾，领先企业利用先发优势建立起安装基础，在路径依赖与正反馈的交互作用下，通过私有协议与领先企业的发展互动，推动私有协议成为所在行业的事实标准。

Abstract: In recent years, proprietary protocol has become an important form of standards in high-tech areas, such as the information and communication industry, which is profoundly changing the state of international standardization. With the case study of Cisco proprietary protocols, the formation mechanism of proprietary protocols is studied. The studies show that proprietary protocol resolves the contradictions between standard lagging and technology development. The leading enterprises establish installation bases by taking advantage of first-mover advantage. Then, due to the effect of path dependence and positive feedback, the proprietary protocol becomes the de facto standard by the interaction between proprietary protocol and leading enterprises.
