Core business regulation and dual diversification patterns in the telecommunications industry
研究了面临核心业务监管的企业如何同时进行产品和国际多元化，基于美国区域贝尔运营公司（RBOCs）的数据提出解释双重多元化模式的方法。
Abstract A firm is confronted with the separate decisions of product and international diversification. It is suggested that these postures are linked to external contingencies in firms who face core business regulation. A technique is developed to explain dual diversification patterns using evidence obtained from the new industry comprised of the Regional Bell Operating Companies (RBOCs).
