考虑服务水平的信息系统运维服务提供商二级价格歧视研究

摘要

By analyzing the effect of information system operation and maintenance service provider′s service lev-el on prices and profits when the two oligarchs competitive providers implement second degree price discrimina -tion in two-period and the n-period, under conditions of linear and nonlinear demand , we obtained the relation-ship between service levels and prices and profits .Studies have shown that prices and profits are proportional to the service levels and the service levels must be maintained at a higher level to ensure profitability in linear de -mand conditions;while in the non-linear demand conditions , the two businesses will still remain profitable at low level of service;at the same time we have come to different segments of the segmented point demand interval . The second degree price discrimination provides a certain reference for information system operation and mainte -nance service providers to set prices when considering the level of service .%通过分析在线性需求和非线性需求条件下，两寡头竞争性信息系统运维服务提供商在二段和n段定价中实施二级价格歧视时，服务水平对提供商的价格和利润的影响，从而得到了服务水平与价格和利润的关系。研究表明：在线性需求条件下，服务水平与价格和利润成正比，且服务水平必须维持在较高的水平之上才能保证盈利，而在非线性需求条件下，服务水平很低时两家提供商仍会保持盈利；同时文中也得出不同分段需求区间的分段点。研究二级价格歧视为信息系统运维服务提供商考虑服务水平定价提供参考。
