After several decades of reform and opening up, China has come to a critical period of transformation and development. How to deepen political reform for this country has once again attracted the world's attention.This book 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, this book adopts the new model to analyse some present practice cases in China. 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. The policy suggestions it proposed will be a valuable reference for policy-makers.
