Luxury goods sell for 50% more in China than in France and Italy, and 20% more than the global average, a Deloitte study has found.
But emerging markets - including China and Russia - continue to drive growth for the sector.
Compared with France, China's highest premium is for watches and jewelry, at 55% more expensive on average, while bags were the lowest, at 40% pricier.
Tourism presents significant opportunities for growth. Almost half of luxury purchases are made by consumers who are traveling in a foreign market - 31% of sales - or at the airport, where 16% of purchases are made.
But uncertainties caused by global developments - including Brexit, the new U.S. administration and terrorist attacks in several European cities - have "deterred many potential Chinese buyers from traveling to key shopping destinations in the U.S. and Europe," Deloitte said.
Consumers in emerging markets continue to drive luxury market growth. In China, Russia and the United Arab Emirates, 70% of consumers surveyed said they have increased their spending on luxury goods over the past five years, while the percentage was only 53% in more mature markets such as Europe and the U.S.
In China, the slowing economy and the central government's crackdown on luxury gifts in the corporate sector have slowed market growth. Nevertheless, demand remains steady, as the country's middle class expands, disposable incomes increase, and the population continues to buy higher-quality products.
Despite the premium that Chinese consumers pay, luxury-goods prices are generally being adjusted downward in the country, to "bring them in line with global markets." These adjustments, Deloitte said, are "encouraging more Chinese consumers to purchase luxury brands in their domestic market."
Globally, however, the 100 largest luxury companies saw their sales drop 4.5% to $212 billion during the fiscal year ending June 2016, driven largely by weak growth of major economies and high debt levels in emerging markets, Deloitte said.
