处于竞争日益激烈的市场环境中,企业经济绩效的好坏直接影响到企业的生存与发展。建筑业作为国民经济的支柱性产业,研究建筑业企业多元化经营对其经济绩效的影响具有重要意义。以2010年以前在上海和深圳两地上市的建筑业企业为样本,对中国建筑业企业多元化经营与其经济绩效的关系进行了实证研究,利用Stata软件对数据进行回归分析,发现企业的多元化经营与总资产收益率(ROA)指标呈正相关,并受企业资产规模、上市时间等因素的影响,该研究为建筑业企业多元化经营与经济绩效关系的研究提供了新的视角,并根据分析结果提出了相应的建议。

In an increasingly competitive market environment,economic performance of enterprises directly influences survival and development of an enterprise.

This study enriches the research perspective in the relationship between construction enterprise diversification and economic performance,and puts forward some corresponding suggestions according to the results of the analysis.
