中文摘要：

相关性分析主要是衡量两个及以上因素之间的相关密切程度。本文首先分析产业结构与展览业是否存在相关性，接着分析产业结构里面什么因素与展览业的相关性最大。为了更好地回答这两个问题，本文通过收集武汉市“十二五”期间经济及展览业发展的相关数据统计，通过灰色关联分析法进行实证分析，结果显示：武汉城市产业结构对展览业存在明显的相关性，且第二产业与展览业的相关性更强；而第二产业里面，汽车及零部件、装备制造等支柱型产业与展览业的相关性要更加明显一些。进一步分析的结果表明，武汉市产业结构与展览面积的相关性要比其与展览数量的相关性更强。

英文摘要：

Correlation analysis refers to the analysis of two or more variables, so as to measure the degree of correlation between them. The paper first analyzes the possibility of correlation between the industrial structure and the exhibition industry, and then analy- zes the correlation between them. In order to answer these two questions, by collecting the data of economic development and the exhi- bition industry in Wuhan City during the ＂ 12th Five -Year＂ period, the paper uses grey correlation analysis method to make an em- pirical analysis, and the results show that the industrial structure and the exhibition industry in Wuhan have obvious relevance, and there is stronger correlation between the second industry and the exhibition industry. What＇s more, in the second industry, motor vehi- cles and parts, equipment manufacturing etc. have more obvious correlation with exhibition industry, at the same time, through further analysis, the correlation between industrial structure and exhibition area of Wuhan is stronger than that of the exhibition quantity.
