這(zhe)一時期，數控機床(chuang)銷售(shou)靠(kao)苦“熬(ao)”行不(bu)通了。杰(jie)克機床(chuang)有限公司董事長陳華貴說，這(zhe)次(ci)危機與2008年(nian)不(bu)同，如果說當年(nian)就如同一次(ci)地震，企業(ye)只要保存實力等待(dai)救援(yuan)就可以了；而(er)(er)這(zhe)次(ci)情(qing)況要復(fu)雜(za)很(hen)多，綜(zong)合了各方面的(de)因素，本質上是(shi)一種(zhong)產能的(de)過剩，是(shi)一次(ci)擠泡沫的(de)過程，企業(ye)必須(xu)搶先(xian)自救。他認(ren)為，雖(sui)然現在(zai)因為市場(chang)(chang)低迷，企業(ye)競(jing)爭加大，但(dan)絕沒有到(dao)達慘烈的(de)程度(du)，最多也就是(shi)比較難(nan)受。“如果一場(chang)(chang)戰役一個(ge)團的(de)人(ren)上去(qu)，能全(quan)身而(er)(er)退的(de)還有上百(bai)號人(ren)，那絕說不(bu)上慘烈。”
