This paper examines how Hong Kong’s economic inequality and political cleavages evolved and where their institutional roots lie. It combines multiple datasets—including household surveys, fiscal records, wealth rankings, and national accounts—with methodological innovations to document a substantial rise in income and wealth inequality over the past four decades. Using recent opinion poll data, it finds business elites with outsized influence in the Legislative Council are more likely to support the pro-establishment camp to protect political and economic interests.

Thomas Piketty and Li Yang Abstract The objective of this paper is to better understand the evolution and institutional roots of Hong Kong’s growing economic inequality and political cleavages. By combining multiple sources of data (household surveys, fiscal data, wealth rankings, national accounts) and methodological innovations, two main findings are obtained. First, he evidence suggests a very large rise in income and wealth inequality in Hong Kong over the last four decades. Second, based on the latest opinion poll data, business elites, who carry disproportionate weight in Hong Kong’s Legislative Council, are found to be more likely to vote for the pro-establishment camp (presumably to ensure that policies are passed that protect their political and economic interests). This paper argues that the unique alliance of government and business elites in a partially democratic political system is the plausible institutional root of Hong Kong’s rising inequality and political cleavages.

Introduction The 2019–2020 Hong Kong protests have garnered significant international attention. Starting in June 2019, demonstrations against a proposed extradition law escalated into a much broader anti-government and anti-Beijing movement that resulted in violent clashes and upset the economic and social order of the city. Protests and demonstrations have indeed been increasing in Hong Kong over the past twenty years, as seen in the July 1 Protests of 2003 and the Umbrella Revolution of 2014 . It is generally believed that the political conflicts over democratic rights that trigged the recent wave of protests have their roots ina set of economic and social conditions that lead to social unrest. One of the most important, but often overlooked, of these conditions is the city’s extreme economic inequality (Ng 2013; Nagy 2015; So 2017; Dieter 2019 ) . This paper aims to better understand the evolution of Hong Kong’s economic inequality and the roots of the widespread social unrest. By combining multiple data sources (household surveys, fiscal data, wealth rankings, national accounts, opinion polls) and innovative methodologies, this study documents a very large rise in wage inequality, Li Yang (corresponding author) is a research associate at the German Institute for Economic Research (DIW Berlin, Mohrenstraße 58, 10117 Berlin, Germany) and a research fellow at the World Inequality Lab; his email address is [lyang@diw.de](lyang@diw.de).
