网络产业Ramsey接入定价方法研究

On the Method of Ramsey Access Pricing in Network Industry

网络产业放松规制、引入竞争的改革使得上游"瓶颈"环节和下游竞争性环节出现了"业务分离,"催生了接入问题,并成为网络产业规制改革能否成功和有效竞争的关键。通过对用于指导网络产业单向接入定价的Ramsey接入定价方法的研究,得出结论:短期内,将接入服务和最终产品无差别对待的做法可能遭受到较大的实阻碍,从而整体最高价格上限规制的实施显得不太可能。因此,比较现实的做法是,在接入服务市场上,允许在位企业实施两部制(或多部制)接入定价方法。

The reform of network industry in terms of deregulation and introducing competition gives rise to the business separation between the upriver bottleneck and the downriver competitive links, which brings on the issue of access and becomes a key to the success of deregulation reform and effective competition in the network industry. This paper expounds the Ramsey pricing method used for guiding the unilateral access pricing of network industry, construes the advantages and disadvantages of Ramsey access pricing method and makes a comparison between the optimal access price decided by Ramsey method and that decided by other access pricing method. Finally, the paper focuses on the issue of implementing the replacement scheme of Ramsey access pricing method.
