But some observers questioned why, if IT had conferred economic value, it did not produce direct competitive advantages for individual firms.Resource-based theory offers an answer, asserting that, in general, firms gain competitive advantages by accumulating resources that are economically valuable, relatively scarce, and not easily replicated.According to a recent study of retail firms, which confirmed that IT has become pervasive and relatively easy to acquire, IT by itself appeared to have conferred little advantage.In fact, though little evidence of any direct effect was found, the frequent negative correlations between IT and performance suggested that IT had probably weakened some firms’ competitive positions.However, firms’ human resources, in and of themselves, did explain improved performance, and some firms gained IT-related advantages by merging IT with complementary resources, particularly human resources. The findings support the notion, founded in resource-based theory, that competitive advantages do not arise from easily replicated resources, no matter how impressive or economically valuable they may be, but from complex, intangible resources.[m2]
A.describing a resource and indicating various methods used to study it
B.presenting a theory and offering an opposing point of view
C.providing an explanation for unexpected findings
D.demonstrating why a particular theory is unfounded
resolving a disagreement regarding the uses of a technology 答案是C，我觉得B也有道理啊，因为我觉得文章写了正反两方的观点，支持这说IT对企业有好处，反对者说，IT没有给企业带来竞争优势。我还查了theory有观点，认为的意思。NN们给解释一下，为什B不对？ 作者: 奇奇大小姐 时间: 2013-1-14 00:53
