副线品牌是指企业为了满足消费者不同的需求和偏好而推出的一个与主品牌定位不同的品牌。副线品牌通常在价格、风格、市场定位等方面与主品牌有所区别，以吸引特定的消费群体。

在企业的品牌战略中，副线品牌的推出可以弥补主品牌的不足，扩大市场份额，增加消费者对企业的认知度和信任度。同时，副线品牌的推出也可以满足消费者对于不同风格和定位的需求，提升企业的市场竞争力。

例如，对于一个以高端奢侈品为主打产品的企业，可以推出一个副线品牌，定位为年轻、时尚、价格适中的产品，以吸引更多的年轻消费者。这个副线品牌可以保持与主品牌的联系，但又有自己独特的特点和定位，以实现市场占有率的扩大。

总的来说，副线品牌的推出是企业品牌战略中的重要一环，可以帮助企业更好地满足消费者需求，扩大市场份额，提升品牌价值。
