我国渔业上市公司多元化战略与经营绩效相关性研究

A study on the correlation between diversification strategy and business performance of listed fishery companies in China

本文以我国渔业上市公司2009-2017年共9年的数据作为样本,以熵指数和专业化率衡量企业的多元化水平,采用因子分析法构建企业的经营绩效评价模型,实证研究多元化战略对渔业上市公司经营绩效的影响。结果发现,渔业上市公司的多元化战略与其经营绩效呈现显著的非相关关系,也即渔业上市公司的多元化与其经营绩效无关,然后尝试对这一结论做出解释,并提出相应对策建议。
