　　with的独立主格中可不可以加that从句呢

　　比如这句话ForthelastfiveyearstheDutcheconomyhasgrownfasterthantheeconomyofBritain,France,andGermany,withtheunemploymentratethathasremainedwellbelowthatoftheotherthreecountries.除了单复数问题外独立主格中的that从句是不是redundant或者awkward了

　　或者这里的单复数没有问题用economies也是可以的？还有with的独立主格是不是需要与主句主语产生呼应？就是例句中with独立主格作为伴随状语的默认逻辑主语是不是theDutcheconomy?
