如何处理好宽带运营商与内容服务商之间的利益关系，实现互联网产业健康快速发展，成为一项亟待解决的重要课题。本项目综合运用问卷调查、实地调研，以及案例研究方法，全面梳理网络中立内涵及其争议，剖析网络中立问题形成原因；基于双边市场理论框架，分析宽带运营商采取不同典型策略行为与新型运营模式所产生的竞争效应，剖析其对各利益相关者福利以及互联网产业发展的影响，并与网络中立约束情况进行比较，明确网络中立原则的利弊；进而分析不同产业改革政策强化抑或弱化网络中立约束需求的影响，并通过数值模拟方法探讨产业未来改革方向；最后基于上述绩效考察，综合考虑我国制度禀赋、现有监管体系特征、监管模式差异、互联网产业现状等影响因素，对我国互联网产业的网络中立监管体系构建提出设计思路与具体措施建议。本项目的研究，不仅能够在一定程度上拓展网络中立问题的理论研究，而且对我国互联网产业改革与监管体系设计具有一定的指导意义。

How to promote a healthy and rapid development of the Internet Industry through coordinating interests between broadband operators and content providers becomes an important issue that requires immediate solution. By conducting questionnaire approach, field research, and case study approach, this project aims to study the meaning and disputation of network neutrality, and analyze the formation process of network neutrality. Furthermore, building on the two-sided markets theory, this project discusses four issues: (1) competitive effects caused by operators' typical strategies and new operating modes; (2) how such competitive effects impact on the welfare of stakeholders and the development of the Internet Industry; (3) the outcome differences between networks with neutrality and networks without neutrality; (4) whether and which industrial policy can strengthen (or weaken) demand for network neutrality regulation. Building on above discussion, and combining the Chinese endowments (such as political institutional resources, current regulatory system, and the Internet Industry status), this project explores (dis)advantages of various net neutrality regulation systems. Moreover, this project proposes plans and concrete suggestions for constructing net neutrality regulation system of China's Internet Industry. This project not only expands our theoretical understanding of the network neutrality, it but also provides insights into reforms of China's Internet industry.
