This book studies the coordination mechanism of labor relations from the perspective of China's law on employer association. The first part of the book examines the definition, functions and institutional basis of employer associations in different types of labor relations, focusing on the complementarity between the law and the coordination mechanism of labor relations in the context of different social environments, institutional frameworks, and their different responses to deregulated labor policies. It then reviews the legislation, responsibilities, and institutional guarantees of employer associations in modern China. The second part outlines the current limitations of legal resources in terms of subject matter, participation mechanisms, and participation channels that constrain the coordination of industrial relations by China's employer associations. The author emphasizes that the systematic legal safeguards of employer associations should be function-oriented and gradually established in a targeted and differentiated manner. The title will appeal to labor and employment law scholars and legislators, and especially to those interested in the law of employer association.
