Post-colonial conservation of colonial built heritage in Hong Kong: A statistical analysis of historic building grading

Based on government appointed specialists' (Antiquities Advisory Board or AAB's) assessments of the heritage value of more than 1400 heritage items in the Hong Kong Special Administrative Region, we found no evidence of nationalistic bias against British or Japanese built military heritage buildings and structures after the handover of Hong Kong to China in July 1997. We also found no evidence of bias in favour of imperial Chinese architecture in the postcolonial period. Incidentally, we found some evidence that suggests AAB's assessments of heritage value for military heritage buildings and structures have increased while those for imperial Chinese architecture have decreased after 1997, which is somewhat puzzling and merits further investigation. The reasons for the results are discussed in terms of the governance of the AAB as a government appointed committee.
