2.2 Market segmentation research review
2.2.1 Definition
Definition: Market segmentation is a marketing strategy which involves piding a broad target market into subsets of consumers, businesses, or countries who have, or are perceived to have, common needs, interests, and priorities, and then designing and implementing strategies to target them. Market segmentation strategies are generally used to identify and further define the target customers, and provide supporting data for marketing plan elements such as positioning to achieve certain marketing plan objectives. Businesses may develop product differentiation strategies, or an undifferentiated approach, involving specific products or product lines depending on the specific demand and attributes of the target segment (An & Chen, 1999, p. 15).
There are many types of market segmentation. The following are the most common forms of market segmentation practices.
Geographic segmentation: Marketers can segment according to geographic criteria—nations, states, regions, countries, cities, neighborhoods, or postal codes. The geo-cluster approach combines demographic data with geographic data to create a more accurate or specific profile (Philip, 2006).
Demographic segmentation: Segmentation according to demography is based on variables such as age, gender, occupation and education level (Reid, 2009, p. 139)or according to perceived benefits which a product/service may provide. Benefits may be perceived differently depending on a consumer's stage in the life cycle. Demographic segmentation pides markets into different life stage groups and allows for messages to be tailored accordingly. 洗发水市场细分对消费者购买行为的影响(2):http://www.751com.cn/yingyu/lunwen_22657.html
