GWD3 24
Most pre-1990 literature on businesses’ use of information technology(IT)—defined as any form of computer-based information system—focused on spectacular IT successes and reflected a general optimism concerning IT’s potential as a resource for creating competitive advantage.  But toward the end of the 1980’s, some economists spoke of a “productivity paradox”:  despite huge IT investments, most notably in the service sectors, productivity stagnated.  In the retail industry, for example, in which IT had been widely adopted during the 1980’s, productivity (average output per hour) rose at an average annual rate of 1.1 percent between 1973 and 1989, compared with 2.4 percent in the preceding 25-year period.  

The author of the passage discusses productivity in the retail industry in the first paragraph primarily in order to
        
F.    suggest a way in which IT can be used to create a competitive advantage
G.    provide an illustration of the “productivity paradox”
H.    emphasize the practical value of the introduction of IT
I.    cite an industry in which productivity did not stagnate during the 1980’s
J.    counter the argument that IT could potentially create competitive advantage
选G
但J为什么不对啊？ 没有以前增长的多了虽然也在增长但是这也说明了它不能创造竞争优势啊，所以反驳。J选项应该对啊。
在做题的时候发现G是没有问题的但看到J又觉得J也没问题。
哪位大牛帮忙解答一下。。。。。。。。。。。。。。。

我认为作者并没有直接反驳：IT’s potential as a resource for creating competitive advantage，重点要放在productivity paradox上面，这个paradox主要是投入产出比的关系，IT投入了很多在服务和零售行业，但是投入产出比率很低，这才是productivity paradox。

举得两个例子，一个服务业一个零售业，都是并列的例子，所起的作用相同。虽然零售业是有增长的，但是比起没有IT投入的时候增长反而滞缓，充分说明了这个productivity paradox多么严重。

所以作者反对的不是IT的作用，而是反对投入了很多IT成本，但是没有收到IT产生的经济效益。所以J是不对的。
