随着住房制度改革和社会主义市场经济体系的逐渐建立,我国城市聚落的旧格局正被打破。从全国各地到来的白领阶层,成为北京、上海、广州、深圳等经济发达城市的“新业主”;而城市的老居民随着城市建设的需要搬出了他们已经居住数代人的“四合院”、“胡同”、“里弄”,先富起来的部分人搬到了城郊的“高尚住宅”。在这眼花缭乱的变动中,一个新的居住小区竣工,迎来了一个新的居住群体,意味着一个新的社区的产生。1997年,原建设部就曾推广过沈阳市的经验,他们在对旧住宅小区整治、改造的基础上,结合房管所转制,推行物业管理,得到了广大住户的拥护和支持。2003年10月,中宣部、原建设部、文化部等部门又联合下发通知,要求全国学习百步亭花园社区创建文明社区的经验。实践使大家深深体会到,物业管理的推进,直接或间接地影响到和谐社区的形成,进而影响到整个城市的和谐。随着物业管理的普及和覆盖面的提高,物业管理者不可忽视这个群体中由于习惯不同、方言不同、职业不同和受教育程度的不同等方面所造成的“文化撞击”。物业管理者只有通过透彻地了解群体成员所表现出来的一定文化环境下的价值观和意识,以及相应的行为方式、需求层次,才能更好地了解既定文化氛围中的组织行为和管理经营重点。
