摘要
以中国上市公司为研究对象,采用最小二乘法和两阶段最小二乘法,借助EViews工具,检验中国机构投资者持股与企业社会绩效的关系,以考察机构投资者基于企业社会绩效的持股偏好和筛选策略,选取2005年至2009年沪深两市918家上市公司为样本进行实证检验。研究结果表明,机构投资者表现出对企业社会绩效的持股偏好,在制定持股决策时会考虑企业社会绩效,尤其是近两年的企业社会绩效。进一步对机构投资者进行分类研究表明,各类机构投资者持股与企业社会绩效关系的差异性较大,仅有基金表现出类似的持股偏好。机构投资者整体和基金的持股偏好是源于筛选策略的介入,正面筛选策略比负面筛选策略对持股偏好的影响程度更大,即机构投资者制定投资决策时以正面筛选策略为主要手段,负面筛选策略为辅。
