山東上原材料價格不斷上漲，近幾年行業市場假冒偽劣、粗制濫造、偷工減料、以次充好現象屢禁不止，不僅埋下了巨大的安全隱患，也導致部分依法生產的企業及經銷商步履維艱。同時，外資企業一直稱霸高端市場，擁有的競爭優勢，給國內電線電纜企業造成了巨大的經營壓力。目前，中國線纜企業數量已突破一萬大關，且大部分是民營企業，市場競爭激烈可想而知。線纜產品良莠不齊，質量出現問題與企業自身有很大關系，因此，企業加大原輔材料采購質量控制力度，注重行業技術創新，提升產品質量。另外，亂象叢生的行業市場，不僅僅是雙芯線線(xian)纜企(qi)業(ye)自(zi)身原因造成的，與(yu)的政(zheng)治體制和經濟發展(zhan)政(zheng)策缺(que)失(shi)也有(you)著莫大的關聯。線(xian)纜行(xing)業(ye)要想突破迎來新生，就需要政(zheng)府和企(qi)業(ye)共(gong)同探(tan)討，制定統一(yi)(yi)的產品標準、規范質量(liang)(liang)、統一(yi)(yi)價格，以改變低價中(zhong)標、質量(liang)(liang)薄弱的市場現狀。行(xing)業(ye)專家建議，中(zhong)國線(xian)纜企(qi)業(ye)不能一(yi)(yi)味(wei)地要追求(qiu)量(liang)(liang)的擴張，更要注重(zhong)質的提(ti)高，加強在(zai)技術(shu)、資金、管理等方面的合作交流，引入先(xian)進技術(shu)和管理理念，使(shi)企(qi)業(ye)實力得到快速提(ti)升，增(zeng)強國際競爭力。
