Book excerpt: The introduction of elections to district advisory bodies during the early 1980s was expected to improve the public delivery of services. However, as time passed, electoral politics led to party politics, elite fragmentation and political struggles. Politicization and hyper-politicization in the Hong Kong Special Administrative Region has brought about a fluctuating pattern between administrative recentralization, the Tsang administration’s attempts at decentralization, and the post-2019 administrative recentralization. The purpose of this book is to study the intertwining relationship between district administration and electoral politics. It also examines the political transformation of District Councils after the promulgation of the National Security Law in late June 2020. Written by experts in the field, this book is a good reference source for readers interested in district elections, politics, and administration in Hong Kong.
