PDA:制胜关键是创新力

供稿人:宋鸿  供稿时间:2004-12-27   关键字:PDA  
掌上电子市场的竞争十分激烈,价格战、概念战、广告战、技术战如火如荼地进行着。但拨开层层战火硝烟,不难发现,掌上电子市场领域内的每一个动作,在很大程度上都是围绕着新产品展开的。
 
在市场规模高速增长的情况下,不可避免的是越来越多的企业(包括国外PDA企业、国内的IT企业、通信企业、家电企业等)都纷纷涉足PDA行业,而对于PDA产品来说,技术的模仿和跟进较快,为了在激烈竞争下争夺更大的市场份额,制胜关键是创新力。所有的企业都希望在技术上寻找更多的卖点,一方面推出具有独特技术卖点的机型,另一方面,对于其他品牌的成功技术卖点迅速跟进,推出机型,进行市场拦截。我们可以从企业申请的相关专利中一窥端倪。
 
以PDA为检索策略,在DERWENT专利数据库中进行了检索(检索日期:2004年11月26日),从2003~2004年各企业申请的专利数量来看,排在前10位的是LG ELECTRONICS INC、SAMSUNG ELECTRONICS CO LTD、NEC CORP、TOSHIBA KK、MATSUSHITA DENKI SANGYO KK、SONY CORP、INVENTEC BESTA CO LTD、MITSUBISHI ELECTRIC CORP、INT BUSINESS MACHINES CORP、HITACHI LTD。它们所占的比率见下图。(各大公司2003~2004年申请的PDA专利数量参见表一。)

对于PDA企业而言,没有创新能力,就没有发展;没有研发能力,企业就举步维艰;没有新产品,市场就裹足不前。
