The "product line---demand---consumers" pyramid" model combining with Maslow"s Need Hierarchy Theory explains the dynamic relationship among the luxury brand"s core products, the main targeted consumers and their main demand. Firstly, competition, sales pressure, market development and other reasons make the core products and product lines growing, namely downward to the bottom of the pyramid; Secondly, with the product line downward to the bottom of the pyramid, the number of luxury consumers has been expanded; Thirdly, because of the exclusive consuming demand, consumers" requirements of conspicuousness and self-fulfillment for the luxury goods are upward to the top of the pyramid.

因此，本研究结合马斯洛需求层次理论，提出了"产品线—需求—消费者金字塔"模型，说明了奢侈品品牌的核心产品、主要目标消费者及其主要需求之间的动态关系：第一，由于竞争、销售压力和市场发展等方面的原因，使得核心产品、产品线有扩大的趋势，即向金字塔下方发展；第二，随着产品线向金字塔下方发展，奢侈品的消费者数量也随之扩大；第三，由于消费需求的排他性，消费者对奢侈品的炫耀性和自我实现性要求则是向金字塔上方发展的。
