互联网服务的成本与费用结构受供应与需求因素影响大,在规模效应与扩容需要双重因素的复杂作用下,目前我国不同地区互联网宽带资费静态差异水平与动态波动幅度较大。本文结合宽带服务的技术经济特点,探讨了宽带服务供求因子的变动性特征,重点剖析了包月制宽带收费模式的优势与不足,提出科学、合理制定与调整宽带资费的理论依据及政策思路。 The cost and expense structure of Internet services are greatly affected by the supply and demand factors. Under the complicated effect of scale factor and capacity expansion requiring double factors, the static disparity and dynamic fluctuation of Internet broadband tariffs in different regions of our country are relatively large. Based on the technical and economic characteristics of broadband services, this paper discusses the characteristics of the fluctuation of supply and demand of broadband services. The paper analyzes the advantages and disadvantages of the broadband subscription model with monthly subscription. The theoretical basis and policy of scientific formulation and adjustment of broadband tariff are put forward.
