摘要： WTO争端解决机制虽然被普遍认为有效和高效，但对发展中成员参与该机制的认识却存在不同的观点，有的认为该机制对发展中国家不公平，有的研究则相反。本文从发展中国家的界定、发展中国家参与情况定量统计、对定量统计的不同角度分析和结论差异进行了探析，认为发展中国家作为整体对于WTO争端解决机制的参与是较积极的，占据了较重要的地位，发挥了相当作用，与在全球贸易中的份额也相适应，但就发展中国家数量来说，参与广泛性还有待提高，这有助于更全面和客观审视发展中国家参与WTO争端解决问题。

Abstract: Although it is generally accepted that the WTO dispute settlement mechanism is efficient and effective，the understandings concerning the participation of developing country members into this mechanism differ．Some researches argue that this mechanism is unfair to the developing members，while some are on the contrary．This paper argues that it is necessary to analyze this issue from multi—perspectives on the basis of various reality factors，and studies the definition of developing country，the statistics of developing country members’participation from two aspects，which will be conducive to full and objective analysis of the subject issue．
