Three of China's leading budget hotel chains have posted strong financial results for the second quarter, underlining the strength of the country's tourism industry.

Home Inns & Hotel Management Inc, 7 Days Inn and Hanting Inns and Hotels all saw strong gains in their revenues during the second quarter of this year, according to their recent financial reports.

Hanting, 7 Days and Home Inns posted revenues of 798 million yuan ($125.42 million), 633 million yuan, and 1.45 billion yuan during the second quarter; up 45.7 percent, 27.3 percent and 60.2 percent year-on-year respectively.

Of the three, only Home Inns saw its profits fall during the period. The slump was blamed on its purchase last May of Motal 168, a struggling budget hotel peer, according to local reports.
