示范诉讼是一种群体性纠纷解决机制,兼具示范功能、试验功能和指示功能。在域外,示范诉讼有契约型示范诉讼、职权型示范诉讼和混合型示范诉讼三种类型。我国有必要引进示范诉讼制度,在程序设置上重点参考契约型示范诉讼,并尽量避免代表人诉讼制度的不足。 Demonstration litigation is a group dispute resolution mechanism that combines demonstration functions, experimental functions and instructional functions. Outside the domain, there are three types of model litigation: contract-type demonstration litigation, power model litigation and hybrid demonstration litigation. It is necessary for our country to introduce the model litigation system, to focus on the contractual model litigation in procedural setting and to avoid the deficiencies of the representative litigation system.
