Job advertisements for IT professionals in Hong Kong increased 11% year-on-year during the second quarter, in an indication that the employment market is improving, according to Robert Walters.

The recruitment firm's quarterly Asia Job Index shows that growth in IT listings outpaced the 6% annual growth in overall job advertisements.

"The beginnings of the recovery in the US and the UK had a positive knock-on effect on the Hong Kong job market," the report states.

"However, the market is likely to maintain a relatively cautious outlook despite these positive indicators due to some uncertainty in an evolving Chinese economy as well as conflicts in the Middle East and Ukraine."

But Hong Kong lagged well behind the Asian average for growth in IT jobs postings. Across the region, listings increased by 31% year-on-year.

In China, IT job advertisements grew by 33%, in a result Robert Walters attributed largely the growth of shared service centers in the mainland.

But the biggest gains were in Singapore, where IT job advertisements increased by 67% year-on-year, in part due to the difficulty employers in the sector are facing attracting talent.

In Malaysia, IT was the sector with the highest annual growth in job listings, with a 55% year-on-year increase. Japan's IT job advertisements increased 30% year-on-year due to a strong demand for IT professionals.
