摘　　要： 利用2003—2012年中国上市公司数据,文章实证分析了企业集团、政府干预及其交互作用对企业投资效率的影响。研究结果表明:首先,企业集团降低了非效率投资从而提高了投资效率,并且企业集团对投资效率的影响具有对称性,即对于过度投资样本,企业集团可以降低过度投资程度;对于投资不足样本,企业集团可以减少投资不足程度。其次,政府干预增加了非效率投资从而降低了投资效率,并且这种影响主要集中于过度投资样本。再次,企业集团可以缓解政府干预对投资效率的负面影响。文章的研究结论对监管机构、上市公司以及投资者均具有重要的启发意义。 Using the data of China’s listed companies during the years from 2003 to 2012 , this paper empirically analyzes the impact of business group and government intervention as well as their interaction upon investment efficiency.
