Beijing

CHINA'S biggest overseas-traded technology companies from search giant Baidu Inc to Sogou Inc are investigating ways to float shares on the country's exchanges, as Beijing encourages its largest corporations to bring their listings home.

Chinese enterprises have long pursued the prestige and capital associated with marquee overseas debuts. But technology businesses from Alibaba Group Holding to Tencent Holdings have in recent years outstripped their old-economy peers to become the nation's largest, and virtually none are traded domestically.
