百度首席技术官李一男辞职查看西安百度陕西博德信息技术有限公司的电子地图

国主要的搜索引擎公司百度在线网络技术公司(Baidu.com Inc.)周一发布公告称，公司首席技术官李一男已因个人原因辞职。

这一消息的发布距百度首席营运长叶朋辞职仅有10天时间。百度称，叶朋也是由于个人原因辞职。

百度未在公告中透露更多细节。目前百度尚未指定这两个职位的继任者。不过，该公司在1月8日宣布叶朋辞职时还表示，提升沈皓瑜为高级副总裁，王湛为副总裁。他们之前分别担任百度商业运营副总裁和商业产品高级总监。

一些市场观察人士猜测，上述管理人士辞职可能与该公司向全新广告系统凤巢(Phoenix Next)过渡的问题有关。

野村证券公司(Nomura Securities)分析师Jin Yoon称，有迹象显示，向凤巢系统过渡可能并没有原先预计的那么顺利。

Yoon还称，百度管理层变动很可能与其主要竞争对手谷歌(Google Inc.)的近期风波无关。谷歌上周称可能全面撤出中国市场。

百度西安分公司Yoon称，谷歌的消息对百度来说应该算是个惊喜。

西安百度推广凤巢系统于去年4月推出，其问世的部分原因是外界批评百度未明确区分广告和正常搜索结果。百度管理层称，该系统还为广告商提供工具，以更好地衡量广告支出回报，从而将在长期内带来更高收入。

但在该公司10月份公布第三季度业绩后举行的分析师电话会议上，沈皓瑜称，习惯于老系统的客户可能到12月1日都不会准备好转用新系统。百度宣布于12月1日全面切换到凤巢系统。

沈皓瑜当时称，这一过渡将导致公司第四季度收入较前一季度增幅减少10个百分点。

李一男2008年10月加入百度，至今仅1年有余。李一男此前是华为技术有限公司(Huawei Technologies Co.)的首席电信科学家兼副总裁。华为是一家总部设在深圳的电信设备生产商。
