本项目旨在研究中国网络外部性产业中的兼容性演化路径与政府引导策略，探讨通过政府引导建立兼容标准协商机制的有效途径，以此促进产品市场竞争，提升社会福利，推动技术创新。具体包括以下几个部分：第一，研究政府引导缺位下，网络外部性产业的非兼容标准竞争机制，分析寡头企业争夺标准主导权的策略竞争，及其对社会福利与技术创新的影响；第二，研究中国在标准设定组织SSO发展尚不完善的现状下，建立政府引导下的企业兼容标准协商机制的有效途径，分析兼容标准协商过程可能出现的信息非对称、低质标准锁定、搭便车等问题的解决方法；第三，量化测度中国网络外部性产业的网络外部性强度与产品兼容性，对网络外部性与兼容性对市场竞争与技术创新的影响效应进行实证分析。通过对非兼容标准竞争机制、兼容标准协商机制的理论分析，及其影响效应的实证研究，为监管机构实施有效的兼容竞争政策提供针对性的政策建议。

This study aims to investigate the evolutionary paths of compatibility in Chinese network industries and regulation policy. By imposing appropriate policy, regulation institution could create effective compatible standards negotiation system, thus to promote market competition, social welfare, and technology innovation. The study process contains three parts. First, we will study the standards war mechanism in Chinese network industries without government participation, including the competition between oligopoly firms for dominating the technique standard, and its influence on social welfare and technology innovation. Second, we will study that while Standard Setting Organizations (SSO) are underdevelopment, how to create an effective standard negotiation system by government guidance. We will discuss several problems which might occur during negotiation, such as non-symmetrical information, locked-in to outdated standard, and free-rider problem. Third, we will quantitatively measure the strength of network externality and compatibility in Chinese network industries. By adopting micro-econometric methods, we will study the influence of network externality and compatibility on consumer demand, market competition, and technology innovation. Summarizing these studies on the mechanism of the incompatible standards war, the mechanism of standards negotiation, and empirical study on their influence, this study could provide valuable recommendations on compatible competition policy in Chinese network industries.
