90年代以来，我国开始出现连锁商业，并把推广、普及连锁商业作为流通企业改革的重点。但是，我们认为，连锁商业的推广和普及是有一定限度的，因为连锁商业同其它商业形式一样也是有边界的：第一，连锁商业的原则是实现进货与销售的分离，而商业的本质却是进货与销售的统一。 Since the 90s, our country began to appear chain commerce, and to promote and popularize chain commerce as the focus of the reform of circulation enterprises. However, we believe there is a limit to the promotion and popularization of chain commerce because chain commerce has the same boundaries as other commercial forms. First, the principle of chain commerce is to realize the separation of purchase and sales, and the nature of commerce Is the purchase and sale of unity.
