This book compares the commons and differences between western and Chinese theories and practices of democracy model, and proposes a new democracy model for China's political reform — "cooperative-harmonious democracy". Absorbing the core values of democracy, this model draws on Chinese traditional "harmony and cooperation" and "people-oriented" thought, as well as modern cooperative game theory. More importantly, it adopts the new model to analyse some present practice cases in China, involving intra-party democracy, electoral democracy, and deliberative democracy. This book is a valuable theoretical innovation and a significant achievement in promoting the interdisciplinary research of political science and public management. It strategically reflects on how to promote the development of cooperative- harmonious democracy from the perspective of high-level design.
