问答题 简答题

甲集团的主营业务是连锁酒店,创立于2005年,2009年11月20日在美国纽约证券交易所上市,作为第一家登陆纽交所的中国酒店集团,甲集团秉承让顾客"天天睡好觉"的愿景,致力于为注重价值的商旅客人提供干净、环保、舒适、安全的住宿服务,满足客户核心的住宿需求。随着经济型酒店市场竞争的加剧,酒店公司的发展方式也在不断变化。目前,除了乙连锁酒店仍在坚持以自主投资的方式在国内发展门店以外,其他的酒店公司均把特许加盟作为发展的首要方式。面临的竞争压力比较大。由于经济型酒店的进入和退出壁垒都比较低,因此仍会有一些新酒店品牌进入到该行业中。投资一家100间客房的经济型酒店只需要四五百万元,预计可在5年回收投资,投资收益率高达20%,因此资金的壁垒较小,非常适合寻求多元化的酒店集团或公司。对于小规模的经济型酒店集团,如果投资者需要退出,则可以把酒店转让给一些全国性的经济型酒店集团,实现资金的退出。另外,由于高星级酒店有较多的客房数,国内的平均入住率水平不高,在酒店的淡季,很多酒店会以较低的价格来吸引顾客,从而在一定程度上跟经济型酒店争抢客源。而社会旅馆、招待所,由于较低的价格吸引了一大批收入不高的旅行者,从而分流了部分客源。许多经济型酒店都是批量进货,购买数量占供应商的销量的很大比例,而且为了降低成本,不接纳进口设备,而且很多酒店以租赁厂房、仓库或者办公楼的方式来开设酒店,其支付的租金水平远远低于市场上正常贸易的租金。经济型酒店品牌众多,且彼此之间的差异化程度很低,购买商的选择余地大。要求:根据以上资料,试用五力模型对酒店行业进行分析。
