1988年,西門子和通用電氣收購英國防務和技術公司Plessey。因為Plessey公司的持有人分裂,因此西門子接收了其航空電子、雷達和交通控制部分,并更名為Siemens Plessey。 2005年,臺灣的明基公司收購了西門子陷入財政危機的移動電話公司并排他性地獲得了五年使用西門子商標的權利,全名為BenQ-Siemens。在將移動電話公司轉讓給明基之前,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。西門子同樣獲得了明基5%約為5000萬歐元的股份。 創新就已成為西門子業務成功的基石。研發是西門子發展戰略的基本動力。作為關鍵專利的持有者,無論是已經成熟的工藝,還是正在發展的技術,我們都是客戶強有力的合作伙伴。我們的目標是,在所涉足的眾多業務,都占據技術領袖地位。 2013年,西門子發言人表示,作為公司60億歐元(約合81億美元)成本削減計劃的一部分,未來一年公司將裁員1.5萬人,其中德國占1/3。 SIEMENS 上海贊國自動化科技有限公司
