Abstract
近日,一则有趣的新闻引起了我的思考。坐落于武汉的一家钢铁企业——武汉钢铁集团(武钢)日前对外宣布,计划投资建立一个年产万头的养猪场。若是一个普通企业也就罢了,然而,武钢是新中国成立后由国家投资建设的第一个特大型钢铁联合企业。人们不禁要问:此举能使武钢从与其本行业完全不相关的多元化产业中获得什么呢?事实上,在跨行业经营问题上,经济学家们早已积累了很多重要的实证研究证据。这些证据表明(至少在美国),涉足不相关产业的多元化经营会损害企业的自身价值,即所谓的“多元化折价”(diversification discount):产业多元化程度非常高的企业其股票的收益率通常较低 (Besanko等, 2007, Chapter 5; Lang 和 Stulz, 1994)。原作者单位: 长江商学
