1988年,西門子和通用電氣收購(gòu)英國(guó)防務(wù)和技術(shù)公司Plessey。因?yàn)镻lessey公司的持有人分裂,因此西門子接收了其航空電子、雷達(dá)和交通控制部分,并更名為Siemens Plessey。 2005年,臺(tái)灣的明基公司收購(gòu)了西門子陷入財(cái)政危機(jī)的移動(dòng)電話公司并排他性地獲得了五年使用西門子商標(biāo)的權(quán)利,全名為BenQ-Siemens。在將移動(dòng)電話公司轉(zhuǎn)讓給明基之前,西門子投入了2.5億歐元并注銷了總值為1億歐元的資產(chǎn)。西門子同樣獲得了明基5%約為5000萬歐元的股份。 創(chuàng)新就已成為西門子業(yè)務(wù)成功的基石。研發(fā)是西門子發(fā)展戰(zhàn)略的基本動(dòng)力。作為關(guān)鍵專利的持有者,無論是已經(jīng)成熟的工藝,還是正在發(fā)展的技術(shù),我們都是客戶強(qiáng)有力的合作伙伴。我們的目標(biāo)是,在所涉足的眾多業(yè)務(wù),都占據(jù)技術(shù)領(lǐng)袖地位。 2013年,西門子發(fā)言人表示,作為公司60億歐元(約合81億美元)成本削減計(jì)劃的一部分,未來一年公司將裁員1.5萬人,其中德國(guó)占1/3。 SIEMENS 上海贊國(guó)自動(dòng)化科技有限公司
