Grassroots democracy has been practised in rural China for more than a decade. However, despite the existence of a mountain of evidence, evaluations of the quality of China's rural grassroots democracy, particularly electoral institutions, have unfortunately been inconclusive, due to primary reliance on case studies and local surveys. Moreover, the lack of comparable data over time prohibits effective studies on the evolution of grassroots democracy in Chinese villages. This article tries to provide some systematic information on how village committee elections are practised and have evolved in China, using two village surveys based on comparable national probability samples, implemented in 2002 and 2005 respectively. It further explores the validity of some key theories in contemporary literature on the uneven implementation of village committee elections in China with the help of an integrated regression model.
