企业多元化是个持续过程,度量企业多元化还须使用动态维度,多元化速度可以作为度量企业多元化的动态指标。基于沪深两市制造业上市公司的数据资料,构建多元回归模型,考察多元化速度对企业市场风险、财务风险、经营风险以及总风险的影响,得出以下结论:短期内,较快的多元化速度能降低企业市场风险、财务风险和经营风险;当经济总体处于快速发展阶段,企业应重视多元化速度所产生的正面影响,不失时机加快多元化速度,促进企业成长。
Based on data of manufacturing companies listed on Shanghai and Shenzhen stock markets,this paper builds a multiple regression model to study the impacts of velocity of diversification on an enterprise's market risk, financial risk, operational risk and overall risk. The result shows that higher velocity will reduce market risk, financial risk and operational risk in the short term. Therefore, enterprises should attach importance to positive influences of diversification velocity to promote growth.
