Some 42 per cent of Chinese millennials tend to shop online, compared with 34 per cent of Generation X – born between the mid-1960s and early 1980s.

The younger generation is also highly active using online and social media channels, such as Weibo and WeChat – with digital media serving as the source of 76 per cent of their latest luxury information, with traditional media accounting for the remaining 24 per cent of information, the report said.

The US remains the biggest luxury market globally, accounting for 22 per cent of all luxury sales; while China is a close second with 21 per cent, the report says.

The Chinese luxury market is forecast to grow each year by 4 per cent over the next five years to reach a value of 617 billion yuan (HK$729 billion) in 2021 – ahead of the expected growth in the worldwide market.

The luxury market growth is expected to be fuelled by the policies introduced by the Chinese government to stimulate domestic consumption of luxury goods, such as the reduction of import duties on products such as cosmetics, luggage and apparel.
