商品同质是非自由竞争的前提研究——兼论完全竞争与自由竞争的关系

Homogeneity of Commodities as the Premise of Non-free Competition——On the Relationship Between Perfect Competition and Free Competition

完全竞争是新古典经济学科学化的根基,商品同质是完全竞争的前提条件之一。商品同质要求商家在同质产品上进行竞争,自由竞争是法律范围内商家想生产什么就生产什么,是自由选择机制,商品同质不是自由竞争的前提。虽然完全竞争的一个条件是资源自由流动,但把完全竞争等同于自由竞争是错误的。商品同质导致商品只有价格竞争,忽视商品的质量竞争,以偏概全。人是趋利避害或理性的,只要人们有自由选择竞争的权力,就不会有完全竞争。

Perfect Competition is the foundation of neoclassical economics.Commodity homogeneity is one of the prerequisites of perfect competition.The same quality of goods requires the merchants to compete on the same quality products.The free competition is what the merchants want to produce within the scope of the law.It is a mechanism of free choice.While a condition of perfect competition is the free flow of resources,it is a mistake to equate perfect competition with free competition.The homogeneity of commodities leads to the price competition of commodities,neglecting the quality competition of commodities.As long as people have the right to freely choose competition,there will be no perfect competition.
