Owning to the influence of the Eastern and Western tradition, religious belief, language worship, there are different apotheoses of the numbers between the East and the West. Besides, there are many things in common and similar laws, especially in the Worship of Number. In the past, scholars at home and abroad usually study the problem from a series of number perspective and few from the specific number perspective. This thesis first of all summarizes the origin and development stages of numerology study, followed by the interpretation of connotation, denotation and the symbolic meaning about SEVEN from semiotics. Later, the article gives the applications of SEVEN in the eastern and western society, culture and daily life, attempting to further compare the connotation, denotation and the symbolic meaning of the Number SEVEN in the East and West. With abundant examples, the paper aims at proving that the connotation and the symbolic meaning of numbers can reflect culture as well as a mode of mind and deed.Key words(黑體，小四號): Semiotics; The Number SEVEN; Culture; Meaning（Times new Roman字體，小四）摘 要（黑體，四號，居中，中間空四格）數是人類思維發展到一定階段，為適應社會生產活動的需要，在符號的幫助下產生的。由于受東西方文化傳統、宗教信仰、語言崇拜、地理環境等方面的影響，數字的神化存在著東西方差異 ，但也存在著共性，有著共同的規律,特別體現在數字“七”上。國內有不少學者就數字寫過著作和論文,但是極少有人從社會符號學的角度探討一個具體的數字在東西方文化中的含義。本文先介紹了數字學的起源和發展，接著從社會符號學的角度解釋了數字“七”的內涵，外延以及象征意義。之后，文章分別列舉了數字“七”在東西方社會、文化、生活上面的運用
