具有購買力的電線電纜市場需求減少。由于全球市場經濟不景氣，我國交聯銅電纜電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)市場也(ye)受(shou)到(dao)重創，需求量一度下(xia)落。但(dan)是進入2018年，市場由于受(shou)到(dao)智網及(ji)寬(kuan)帶工程建設有利促進，目前(qian)正在逐(zhu)步恢(hui)復當(dang)(dang)中，但(dan)對電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業的(de)(de)利潤(run)緩(huan)解作用較(jiao)為(wei)有限。原(yuan)(yuan)材價格(ge)不穩定，嚴重積壓(ya)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業的(de)(de)利潤(run)。電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業的(de)(de)特(te)點是料重工輕利薄(bo)，當(dang)(dang)原(yuan)(yuan)材價格(ge)上(shang)漲時(shi)，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業購買原(yuan)(yuan)材將造(zao)(zao)成銀根(gen)吃緊(jin)，資(zi)金周轉緩(huan)慢。而當(dang)(dang)原(yuan)(yuan)材價格(ge)下(xia)跌，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業又回因為(wei)來(lai)不及(ji)消化(hua)原(yuan)(yuan)材，而造(zao)(zao)成出廠(chang)價急速(su)下(xia)跌。兩者間(jian)(jian)的(de)(de)兩者之間(jian)(jian)的(de)(de)“剪刀差”與“時(shi)間(jian)(jian)差”嚴重擠壓(ya)了電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業的(de)(de)盈利空(kong)間(jian)(jian)。目前(qian)行(xing)業普遍比較(jiao)認可的(de)(de)說法是，原(yuan)(yuan)材價格(ge)原(yuan)(yuan)材料價格(ge)每(mei)上(shang)漲5%，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業的(de)(de)相對利潤(run)則將減少4%。銀行(xing)貸款利息的(de)(de)不斷增(zeng)加，同樣給電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業的(de)(de)利潤(run)空(kong)間(jian)(jian)造(zao)(zao)成重大(da)影響。由于目前(qian)我國的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)企(qi)(qi)(qi)業基本(ben)都(dou)是民營企(qi)(qi)(qi)業，因此即使比較(jiao)幸(xing)運能夠帶到(dao)款，但(dan)是利率一般(ban)也(ye)要上(shang)浮40%左(zuo)后，何況(kuang)有眾多企(qi)(qi)(qi)業根(gen)本(ben)就融(rong)不到(dao)資(zi)。融(rong)資(zi)難的(de)(de)問(wen)題直(zhi)接造(zao)(zao)成我國整個電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業的(de)(de)資(zi)金回籠周期變慢，三角債盛行(xing)。
