本文通过构建有边缘零售竞争者的主导零售商模型,考察了零售商抗衡力量对市场绩效的影响,理论上证明了“加尔布雷斯假说”在一定条件下成立。研究表明:零售商适度的抗衡力量对社会是有利的,但前提是零售层面存在竞争。文章最后针对我国零售市场特点,提出了抗衡力量的反垄断政策涵义。
By constructing a leading retailer model with marginal retail competitors, this paper examines the impact of retailers’ countervailing forces on market performance and theoretically proves that the “Gabbrase hypothesis” is established under certain conditions. Research shows that retailers’ modest countervailing power is good for society, but only if there is competition at retail level. Finally, according to the characteristics of China’s retail market, the article puts forward the antitrust policy meaning of countervailing power.
