A senior member of a leading national think tank on Thursday said he thinks the reshuffle of the SAR cabinet will serve as a stimulus for better governance.

Lau Siu-kai, a consultant to the Chinese Association of Hong Kong and Macau Studies, told RTHK that he's not surprised by the new appointments.

"Under the principal officials' accountability system, it is quite normal for the chief executive to replace ministers from time to time so that he can get his job done better, get his government more popular, and to be seen as accountable to the public," he said.

The replacements will also push existing officials to do a better job to "avoid being replaced by new ministers" and to improve overall government performance, Lau added.

"I would say the public... expect them to do a much better job than their predecessors, given their two predecessors have done something which has been quite controversial before. The new ministers should be able to elicit new expectations from the public or the government."

Lau said the new culture and transport chiefs are expected to outperform their predecessors, and ensure smooth sailing of important projects like the Kai Tak Sports Park and next year's National Games.

"In the next couple of years, the chief executive must be very concerned that the Kai Tak Sports Park and the national sports event will be held very successfully, and no mistake will be committed.

"If that is the case, it is not surprising that he is going to replace two officials. He will be more comfortable with the new ministers and be confident that they can get the job done and to enhance the popularity and the authority of the government."

Lau added that he thinks the two new ministers are hardworking and willing to face the media, and will work closely with professionals in their bureaus.
