Hong Kong ranks third-best globally for "human freedom", topping such well-established democracies as the United States and United Kingdom, according to the research from the Fraser Institute, a Canadian think tank. The mainland stood at 100th.
The city was the star performer for economic freedom - scoring 9.02 out of 10. But in terms of personal freedom, or civil liberties, it measured 7.8, worse than at least 49 countries.
This gave it an overall score on the "human freedom index" of 8.39, below New Zealand and the Netherlands. The US was ranked 7th and the UK 18th.
"No nation that has adopted economic freedom has ever failed to evolve towards civil and political freedoms, with only two possible exceptions: Singapore and Hong Kong," the report noted. "The great question for the future is whether ... market reforms ultimately lead to other freedoms in [mainland] China."
The mainland was given 5.1 and 6.44 points for personal and economic freedom respectively.
