摘要 文章研究了公司的系统风险、债务风险和经营风险与公司的多元化程度的相关性。本文的实证结果表明,公司的系统风险与公司的多元化程度是正相关的;公司的债务风险与公司的多元化程度是正相关的;公司的经营风险与公司的多元化程度是负相关的。随着公司多元化程度加深,公司的经营风险会变小,但是公司面临的宏观的资本市场的系统风险和企业自身的债务风险,会随着变大。 This paper studies the correlation analysis for companies'diversification and systematic risk,credit risk and operational risk.We find that companies'diversification is positively related to their systematic risk and credit risk,and negatively related to their operational risk.The study indicates that companies' operational risk decreases,while their systematic risk and credit risk increase,with companies'diversification increasing.
