【摘要】：本文强调ICT基础设施对经济发展具有战略性作用,并以中国电信市场为建模背景,构建理论模型深入研究ICT基础设施的投资方式,回答了ICT基础设施投资是否应该由市场主体完全承担,以及政府如何选择最优政策工具的问题。本文指出,完全由市场主体承担ICT基础设施投资无法实现最优效率水平;使用基础设施资本时产生的外部性会导致私人收益和社会收益之间发生差异,需要政府进行干预;政府只依靠所得税还无法恢复最优效率水平,而依靠最优补贴则能矫正多种扭曲,并修复基础设施投资激励,将社会配置效率恢复到最优。同时,本文也提供了政府改进政策手段的理论依据。本文利用这一理论剖析了中国的宽带发展问题,指出将宽带纳入国家基础设施管理体系,加大对宽带投资补贴,应成为今后电信投资体制的重要改进方向。
[Abstract]:This paper emphasizes that ICT infrastructure plays a strategic role in economic development, and builds a theoretical model to study the investment mode of ICT infrastructure, taking the Chinese telecom market as the modeling background. The question of whether ICT infrastructure investment should be fully borne by market players and how the government chooses the best policy tools is answered. This paper points out that it is impossible to achieve the optimal efficiency level for ICT infrastructure investment to be borne entirely by market agents, and that the externalities generated when using infrastructure capital will lead to differences between private and social benefits, which require government intervention. The government can not restore the optimal efficiency level by income tax alone, and the optimal subsidy can correct many distortions, repair the infrastructure investment incentives, and restore the social allocation efficiency to the optimum. At the same time, this article also provides the government to improve the policy means of theoretical basis. Based on this theory, this paper analyzes the development of broadband in China, and points out that bringing broadband into the national infrastructure management system and increasing the subsidy for broadband investment should become an important direction of improving the telecommunication investment system in the future.
