外资零售企业进入、混合竞争与中国培育大型流通企业政策——基于混合寡占博弈模型的流通政策分析

组建与培育具有国际竞争力的大型国有控股流通企业集团是转型经济时期我国政府的一种积极的市场治理方式。通过构建三类混合寡占零售博弈模型和均衡分析表明,在多种所有制零售企业共同参与竞争时,国内社会总体福利的大小与外资零售企业的信息技术管理水平并不成简单正相关关系;当国有零售企业完全以社会总剩余最大化为目标时,即使其效率低于外资企业、市场的价格小于国有企业的边际成本,它的存在也将提升社会福利;国有零售企业具有规定市场规模、维护市场稳定的重要功能;明确国有流通企业在不同状态下目标函数预期,合理构建零售市场的组织结构与所有制结构,可以有效增强我国零售市场的供给保障和调控能力。

Foreign Retailer Entry, Mixed Competition and the Large-Retailer Cultivation Policy: Macro Retailing Policy Analysis Based on Mixed Oligopoly Model

The cultivation of large state-owned retailers is viewed as a positive government policy in current China’s transitional period.This paper constructs a mixed oligopolistic retailer competition model.The equilibrium analysis shows that with the mixed ownership retailers mutual competition,total domestic social surplus is not always positively correlated with the foreign firm’s technology and management level.While the state owned retailers(SOR) maximize the social surplus as their target,their entrance can improve the social objects achievement even if their efficiency is lower than the foreign counterparty or the price is lower than the marginal cost.To some extent,the large state owned retailer can determine the retail market scale and maintain the market stability.This conclusion means that given the clear expectation of SOR’ s state-contingent objective function,the retailing market’s supply security and governance can be improved through the specific mixed organization and ownership structure arrangement.
