随着消费者品尝能力的逐步提高,未来增长最快的细分市场将是中高档葡萄酒。据预测,到2010年我国对葡萄酒的需求高档酒占到50%,中档酒占到40%,而低档酒只占10%.另外,由于政府加强相关政策的制定,将使部分低质酒和劣质酒失去生存的空间。而国外葡萄酒的顶级品牌早晚都要进入中国,留给本土品牌的时间不多了。某家国内专门生产葡萄酒的企业,意识到了塑造自己独特的葡萄酒品牌的重要性,该公司领导想尽快在国内市场上打出自己的品牌。为了验证这个市场,该公司决定进行一次市场调研,通过实地调查来了解消费者对该品牌的了解。于是该公司请A市场调研公司为其提供市场调研问卷,自己组织调研。但在实际调查过程中却出现了问题:很多被调查者不愿意提供合作,认为该问卷太复杂,很多问题都不理解:并且填这样的问卷太浪费时间,而且还有些问题涉及到了个人隐私。因此,该公司并没有取得自己想要的东西,为此公司召开了专门的会议讨论问题的所在。
请帮助该葡萄酒生产企业重新制定一个市场调研计划。
