种群的竞合过程中,优胜者一方意味着更有效的资源应用,获取更广阔的生存空间,直至完全排斥某一种群,或者在种群间在达到某一平衡点后和谐共处。除同质市场或单一产品市场外,产品差异化普遍存在,在产品线延伸策略中,新产品抑或新产品种群在被推入市场后,必定会侵占原有产品的市场空间。 During the process of population co-movement, the winner means more effective resource application and more space for survival until a complete rejection of a certain population or harmonious coexistence between the populations after reaching a certain balance point. In addition to homogeneous market or single product market, product differentiation is ubiquitous. In the product line extension strategy, new product or new product population will inevitably occupy the market space of the original product after it is pushed into the market.
