摘要翻译：
运用随机矩阵理论，研究了中国股票市场、美国股票市场和全球股票市场指数的空间结构。在考虑互相关矩阵特征向量中各分量的符号后，我们检测了金融系统的子部门结构。正负子扇区在对应的本征模中相互反相关。中国股市的子行业结构较强，而美国股市和全球市场指数则略弱。揭示了不同市场分部门结构的特点。

英文摘要：
With the random matrix theory, we study the spatial structure of the Chinese stock market, American stock market and global market indices. After taking into account the signs of the components in the eigenvectors of the cross-correlation matrix, we detect the subsector structure of the financial systems. The positive and negative subsectors are anti-correlated each other in the corresponding eigenmode. The subsector structure is strong in the Chinese stock market, while somewhat weaker in the American stock market and global market indices. Characteristics of the subsector structures in different markets are revealed.
