這(zhe)一(yi)時期，數(shu)控(kong)機(ji)(ji)床(chuang)銷售靠苦(ku)“熬”行不通了(le)。杰克機(ji)(ji)床(chuang)有限(xian)公司(si)董事長陳華貴(gui)說，這(zhe)次危機(ji)(ji)與2008年不同(tong)，如(ru)果(guo)說當年就如(ru)同(tong)一(yi)次地震(zhen)，企業只要(yao)保存實力等待(dai)救援(yuan)就可以了(le)；而這(zhe)次情況(kuang)要(yao)復雜很多，綜(zong)合了(le)各方面的因(yin)素(su)，本質上是一(yi)種產能(neng)(neng)的過(guo)剩，是一(yi)次擠泡沫的過(guo)程，企業必須(xu)搶先自(zi)救。他認為，雖然現在(zai)因(yin)為市場低迷，企業競爭(zheng)加大，但絕(jue)沒(mei)有到達慘烈的程度，最多也就是比較難受。“如(ru)果(guo)一(yi)場戰(zhan)役一(yi)個(ge)團的人(ren)上去，能(neng)(neng)全身而退的還(huan)有上百號人(ren)，那絕(jue)說不上慘烈。”
