随着经济全球化的加快和我国加入 WTO的日益临近 ,“小额多数”的现代型纠纷不断涌现 ,但我国的代表人诉讼制度存在严重的功能缺陷。以法律的经济分析为理论视角 ,比较中外四种典型群体诉讼制度的起诉成本 ,我国代表人诉讼制度的起诉成本最大 ,其后依次是选定当事人制度、团体诉讼、集团诉讼。这也正是作为“经济人”的广大消费者不愿进行代表人诉讼的重要原因之一。 With the acceleration of economic globalization and the approaching of China’s accession to the WTO, the “small majority” modern disputes continue to emerge. However, there are serious functional deficiencies in China’s representative lawsuit system. From the perspective of economic analysis of law, comparing the cost of prosecution of the four typical group litigation systems in China and foreign countries, the cost of litigation in our representative litigation system is the largest, followed by the system of selected parties, group litigation and group litigation. This is also one of the important reasons that the vast number of consumers who are “economic people” are unwilling to carry out representative litigation.
