In this paper, the identification theory based on characteristics of the inner pages is presented for the first time. This theory cannot be ignored in the identification of Naxi manuscripts. The identification theory based on characteristics on the inner pages is divided into identification based on inner page format, identification based on illustrations, identification based on frame and identification based on initials and separators. The rationality of identification theory based on characteristics on the inner pages is confirmed through demonstrations. At last, principles, rules and limitations of identification based on characteristics on the inner pages are summarized. The advantage of this theory is simple and effective, and the disadvantage is too dependent on scriptures inside pages of the style and color.

摘要：本文首次提出了内页特征鉴定法，它在东巴经鉴定中的地位不能忽略。内页鉴定法鉴定方法是基于东巴经内页特征而提出的方法，其内涵包括根据首页版式鉴定，根据插图鉴定，根据边框鉴定、根据起首符号和分隔符号鉴定四个部分。本文通过哈佛藏东巴经书示例，验证内页特征鉴定法的合理性，最后总结出了内页特征鉴定法的总体原则、具体条例及局限。这种方法的优点在于能简单和有效鉴定经书，缺点在于过于依赖经书内页的样式和上色情况。
