Not a single one of the biggest public companies in Hong Kong employs a female CEO, according to new analysis from business intelligence company QlikView.

The company has compiled research into the make-up of Asia's business leaders into the new interactive application Where do APAC CEOs come from?

For the research, QlikView compared the CEOs of the top 250 Asia-Pacific entrants in the 2013 Forbes Global 2000 list of the largest public companies. Among the Hong Kong companies in the list, none has a female CEO.

Announcing the results, QlikView said this demonstrates that efforts to improve gender diversity in the boardroom have been slow to enact any real change.

Nearby countries aren't faring much better, with only 2% of CEOs from the Chinese companies being women, and only 5% from Singapore. Across APAC, 96.8% of the CEOs of top companies are male

The analysis shows that the average age for a Hong Kong CEO is 54. But the city also has the oldest and youngest CEO of a large public company in Asia-Pacific, aged 33 and 84 respectively.

Hong Kong CEOs are also among the most likely in APAC to have graduated from an overseas university (82.4%), and to have a MBA (30%, compared to an APAC average of 23%).

The majority (60%) of the Hong Kong CEOs have been in the job for less than five years, and 70% have less than 10 years of experience as CEOs. In contrast, one Hong Kong CEO has been in power for over 35 years.
