A theory of political divergence and gradual institutional change

AJPS — 2026-08-20 Original A theory of political divergence and gradual institutional change Clair Yang Abstract Abstract Why do some societies succeed in breaking away from historical traditions while others remain trapped? This paper proposes a formal theory to investigate the interaction between short‐run and long‐run political dynamics, highlighting a co‐evolution of political institutions and social structures. A society consists of various social groups, such as the rulers, the elites, and the commoners. Short‐run strategic considerations give rise to different coalitions among these groups, which determine not only political regimes but also redistribution policies. In the long run, these policies shape the accumulation of wealth and power, where small initial differences can lead to divergent paths of development. Finally, the paper examines three historical case studies on medieval Europe, imperial China, and the medieval Muslim world to illustrate potential pathways of long‐run political development.

Rising Engagement and Substantive Responsiveness: 13 Years of Online Petitioning in China

CQ — pp. 1-17 2026-08-05 Original Rising Engagement and Substantive Responsiveness: 13 Years of Online Petitioning in China Matt DeButts, Tongtong Zhang Abstract Abstract The Chinese government has invested heavily in online petition platforms to channel public grievances, yet systematic longitudinal evidence on citizen–state interactions within these venues remains limited. This research report presents nationwide evidence showing that both public participation and government responsiveness through e-petition institutions have increased markedly since Xi Jinping took office. Analysing more than four million citizen appeals submitted to the country’s largest online petition portal, Message Board for Leaders, from January 2011 to January 2024, we find a twelvefold rise in petition volume and a fivefold increase in users, largely driven by urban residents in eastern provinces. Appeals have also diversified, with notable growth in housing-related issues and more strategic appeals directed at Party secretaries. Meanwhile, local governments have raised response rates from 50 per cent to 98 per cent, shortened average wait times from 176 to 19 days, and increased the substantive resolution rate from 17 per cent to 31 per cent over the past decade.
