This book presents a scientifically rigorous methodology that incorporates multidisciplinary, multi-dimensional, multi-agent, and multi-perspective approaches to energy policy and international energy cooperation. It offers an in-depth analysis of fundamental theories and conducts comprehensive research on the energy policies of ten major global producers and consumers. Through a detailed examination, the book explores the impact of these policies on international cooperation. Key concepts include the exploration of foundational theories from a multidisciplinary perspective, systematic analysis of energy policies within a five-dimensional framework, and the organization of typical cases of international energy cooperation. The book highlights the roles of bilateral and multilateral alliances and examines the effects of energy policies through various dimensions such as legal regulations and fiscal tools. By addressing these critical issues, it provides valuable insights into the dynamic interplay between energy policy and international cooperation. This book is essential for researchers, scholars, and policymakers in the field of energy studies. It offers a scientific reference and policy recommendations for ensuring sustainable and efficient global energy cooperation. Whether you are a seasoned expert or a newcomer to the field, this book will enhance your understanding of the complexities of energy policy and international collaboration.

In 1939, residents of a rural village near Chengdu watched as Lei Mingyuan, a member of a violent secret society known as the Gowned Brothers, executed his teenage daughter. Six years later, Shen Baoyuan, a sociology student at Yenching University, arrived in the town to conduct fieldwork on the society that once held sway over local matters. She got to know Lei Mingyuan and his family, recording many rare insights about the murder and the Gowned Brothers' inner workings. Using the filicide as a starting point to examine the history, culture, and organization of the Gowned Brothers, Di Wang offers nuanced insights into the structures of local power in 1940s rural Sichuan. Moreover, he examines the influence of Western sociology and anthropology on the way intellectuals in the Republic of China perceived rural communities. By studying the complex relationship between the Gowned Brothers and the Chinese Communist Party, he offers a unique perspective on China's transition to socialism. In so doing, Wang persuasively connects a family in a rural community, with little overt influence on national destiny, to the movements and ideologies that helped shape contemporary China.
