Feb 27 (Reuters) - China's Baidu fell short of analysts' estimates for fourth-quarter revenue on Wednesday, as advertisers kept a tight leash on their spending budgets amid an uneven economic recovery in the Asian powerhouse.

Revenue was 34.95 billion yuan ($4.92 billion) for the three months ended December, compared with analysts' average estimate of 34.97 billion yuan, according to LSEG data.
