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，不僅僅是低壓銅芯鎧裝電纜線纜企業(ye)(ye)(ye)自(zi)身原因造成的(de)，與的(de)政治體制(zhi)和(he)經濟(ji)發展政策缺(que)失也有(you)著莫大(da)的(de)關聯。線纜行(xing)業(ye)(ye)(ye)要(yao)(yao)想突(tu)破(po)迎(ying)來新(xin)生，就需要(yao)(yao)政府和(he)企業(ye)(ye)(ye)共同探討，制(zhi)定統(tong)一(yi)(yi)的(de)產品標(biao)準(zhun)、規(gui)范質(zhi)量(liang)、統(tong)一(yi)(yi)價格，以改變低價中標(biao)、質(zhi)量(liang)薄弱(ruo)的(de)市(shi)場現狀。行(xing)業(ye)(ye)(ye)專家建議，中國線纜企業(ye)(ye)(ye)不能一(yi)(yi)味(wei)地要(yao)(yao)追(zhui)求量(liang)的(de)擴張，更要(yao)(yao)注(zhu)重質(zhi)的(de)提高，加強在(zai)技(ji)術、資金、管理等方面的(de)合作交(jiao)流，引入先進(jin)技(ji)術和(he)管理理念，使企業(ye)(ye)(ye)實力得到快速提升，增強國際競爭力。
