目前,我國電(dian)線(xian)(xian)電(dian)纜行(xing)業(ye)(ye)(ye)(ye)產(chan)(chan)業(ye)(ye)(ye)(ye)鏈(lian)較為成(cheng)熟,上游行(xing)業(ye)(ye)(ye)(ye)主要為提(ti)供(gong)制造電(dian)線(xian)(xian)電(dian)纜產(chan)(chan)品原材料的(de)(de)基礎材料行(xing)業(ye)(ye)(ye)(ye)以及制造交(jiao)聯絕(jue)緣套及護套料的(de)(de)橡膠(jiao)行(xing)業(ye)(ye)(ye)(ye),如銅、鋁及其合(he)金、聚乙(yi)烯、聚氯乙(yi)烯化(hua)工(gong)行(xing)業(ye)(ye)(ye)(ye)等(deng)(deng);中游包括提(ti)供(gong)電(dian)力電(dian)纜、通信(xin)電(dian)纜、電(dian)氣裝備(bei)用電(dian)纜及裸(luo)電(dian)線(xian)(xian)、繞組線(xian)(xian)等(deng)(deng)其他(ta)類型電(dian)纜的(de)(de)電(dian)線(xian)(xian)電(dian)纜生產(chan)(chan)制造企業(ye)(ye)(ye)(ye);下游主要為對電(dian)線(xian)(xian)電(dian)纜有需求的(de)(de)行(xing)業(ye)(ye)(ye)(ye),如工(gong)程(cheng)機械、通信(xin)行(xing)業(ye)(ye)(ye)(ye)、電(dian)力行(xing)業(ye)(ye)(ye)(ye)、石油化(hua)工(gong)及建(jian)筑(zhu)行(xing)業(ye)(ye)(ye)(ye)等(deng)(deng)。

 

 

從企(qi)(qi)業(ye)(ye)來(lai)看,上(shang)游(you)銅(tong)、鋁及其合金供(gong)應商為(wei)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)產業(ye)(ye)提供(gong)主(zhu)(zhu)要組(zu)成(cheng)材料,主(zhu)(zhu)要企(qi)(qi)業(ye)(ye)有(you)銅(tong)陵有(you)色、楚(chu)江(jiang)新材、海亮(liang)股(gu)份(fen)等。在中游(you)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)制(zhi)造行業(ye)(ye)中,制(zhi)造電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)的(de)主(zhu)(zhu)要企(qi)(qi)業(ye)(ye)有(you)特變電(dian)(dian)(dian)工、青島漢纜(lan)(lan)等;制(zhi)造通(tong)信電(dian)(dian)(dian)纜(lan)(lan)的(de)主(zhu)(zhu)要企(qi)(qi)業(ye)(ye)有(you)中天科(ke)技、亨通(tong)集團等;制(zhi)造電(dian)(dian)(dian)氣裝備(bei)用(yong)電(dian)(dian)(dian)纜(lan)(lan)的(de)主(zhu)(zhu)要企(qi)(qi)業(ye)(ye)有(you)金杯電(dian)(dian)(dian)工、杭州(zhou)電(dian)(dian)(dian)纜(lan)(lan)等;制(zhi)造裸電(dian)(dian)(dian)線、繞組(zu)線的(de)主(zhu)(zhu)要企(qi)(qi)業(ye)(ye)有(you)精達股(gu)份(fen)、遠程股(gu)份(fen)等。

 

行業發(fa)展歷程:步入成熟期

 

我(wo)國(guo)(guo)(guo)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)發展史(shi)起步比較晚,第一家(jia)電(dian)(dian)(dian)纜(lan)廠(chang)(chang)——昆明(ming)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)廠(chang)(chang)于1939年7月(yue)1日正(zheng)式(shi)投產(chan)。1948年,昆明(ming)電(dian)(dian)(dian)線(xian)廠(chang)(chang)生產(chan)出6.6kV橡皮絕緣(yuan)鉛包電(dian)(dian)(dian)纜(lan)。新中國(guo)(guo)(guo)成立后(hou),1954年建(jian)立沈陽電(dian)(dian)(dian)纜(lan)廠(chang)(chang)(蘇聯援建(jian)),1956年正(zheng)式(shi)投產(chan),我(wo)國(guo)(guo)(guo)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)生產(chan)從無到有(you)。20世紀(ji)60年代以(yi)來,我(wo)國(guo)(guo)(guo)在導體生產(chan)和(he)科研方面進行了大量的(de)工作,生產(chan)出電(dian)(dian)(dian)工鋁(lv)導體。20世紀(ji)80年代末,電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)行業(ye)產(chan)值占國(guo)(guo)(guo)民(min)經濟(ji)產(chan)值的(de)0.88%;到1998年,我(wo)國(guo)(guo)(guo)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)產(chan)值占國(guo)(guo)(guo)民(min)經濟(ji)總產(chan)值1%,反映出它(ta)仍有(you)較強(qiang)的(de)生命(ming)力。

 

20世紀(ji)90年(nian)代以來,我國電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)業獲得高(gao)速(su)發展,中國也(ye)是(shi)僅次于美國的(de)世界第二大電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)生產國。2011年(nian),中國電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)產業規模(mo)首次超過美國,成(cheng)為全球電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)行(xing)業第一大市(shi)場(chang)。隨(sui)后,隨(sui)著我國電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)市(shi)場(chang)快速(su)發展,行(xing)業已經步入(ru)成(cheng)熟階段。

 

行業政策背景:加快特高壓及智能電網建設

 

 

近(jin)年(nian)來,政府各(ge)部門發布了一(yi)系列(lie)的政策法(fa)規以推動(dong)國內電(dian)線電(dian)纜行業健康、快速地發展。《中華人(ren)民共(gong)和(he)國國民經濟和(he)社(she)會發展第十四個五年(nian)規劃和(he)2035年(nian)遠景目標綱要》提出,提高特高壓輸(shu)電(dian)通道利(li)用率,加(jia)快電(dian)網基(ji)礎設(she)施智(zhi)能(neng)化(hua)改造和(he)智(zhi)能(neng)微電(dian)網建設(she),提升向邊遠地區(qu)輸(shu)配電(dian)能(neng)力(li)。

 

 

行業發展現狀

 

1、企業數量眾多

 

我國電(dian)線電(dian)纜行(xing)業(ye)的企(qi)業(ye)數量眾多(duo),其中(zhong)以中(zhong)小企(qi)業(ye)居多(duo)。根據中(zhong)國企(qi)業(ye)數據庫企(qi)查貓(mao),截至2022年(nian)12月27日,中(zhong)國電(dian)線電(dian)纜行(xing)業(ye)的主要企(qi)業(ye)共有30300家(jia),其中(zhong)以2021年(nian)為主要注冊熱潮,當年(nian)注冊企(qi)業(ye)數量為2095家(jia),而2022年(nian)則為778家(jia)。

 

注:篩(shai)選邏輯(ji)為(wei)名(ming)稱、產品服(fu)務(wu)和經營范(fan)圍(wei)中包含(han)了“電線電纜(lan)”的企業,行業歸(gui)類(lei)從屬于國民經濟(ji)分類(lei)的“電線、電纜(lan)、光纜(lan)及電工器(qi)材制造(zao)”。

 

2、電力電纜及光纜產量均有所回升

 

國(guo)家統計局數(shu)據(ju)顯示,2011年以來,我國(guo)電(dian)力電(dian)纜總(zong)產(chan)量整體呈現震蕩走勢。在經歷2017-2018年連續(xu)兩年產(chan)量規(gui)模(mo)下滑之后,2019年,我國(guo)電(dian)力電(dian)纜總(zong)產(chan)量規(gui)模(mo)有所回升(sheng),整體規(gui)模(mo)達到(dao)5141萬千米,同比(bi)(bi)增長(chang)13.44%。2021年,隨著(zhu)疫情逐(zhu)步好轉,國(guo)內電(dian)力電(dian)纜產(chan)量達到(dao)5480萬千米,同比(bi)(bi)增長(chang)4.52%。

 

光(guang)纜方面,國(guo)家統(tong)計(ji)局數(shu)據(ju)顯示,2011-2021年(nian)(nian),我國(guo)光(guang)纜產量(liang)(liang)整體呈波動變(bian)化。2021年(nian)(nian)下半(ban)年(nian)(nian)以來,尤其是(shi)2021年(nian)(nian)10月(yue)以來,中國(guo)移動、中國(guo)電信等(deng)運營商對普通光(guang)纜產品等(deng)集采(cai)招(zhao)標呈現(xian)量(liang)(liang)價(jia)齊升(sheng)的趨勢,采(cai)購(gou)規模和(he)(he)價(jia)格(ge)均較(jiao)上(shang)年(nian)(nian)實(shi)現(xian)較(jiao)大幅度(du)上(shang)升(sheng)。一(yi)直到(dao)2022年(nian)(nian)上(shang)半(ban)年(nian)(nian),中國(guo)聯(lian)通和(he)(he)中國(guo)廣電也(ye)進行了相(xiang)關光(guang)纜產品的集采(cai)。2022年(nian)(nian)前三季(ji)度(du),國(guo)內光(guang)纜產量(liang)(liang)累(lei)計(ji)值達到(dao)2.64億芯千米(mi),光(guang)纜產量(liang)(liang)累(lei)計(ji)增長(chang)11.5%。

 

3、價格指數居于高位

 

近年來,我(wo)國普通(tong)電(dian)力電(dian)纜(lan)、光電(dian)線纜(lan)、通(tong)用裝備線纜(lan)企業(ye)數(shu)(shu)(shu)量較多,產(chan)能已經(jing)過(guo)剩,市(shi)場陷入以(yi)價(jia)格(ge)(ge)競爭(zheng)(zheng)為(wei)主的(de)低(di)水平(ping)惡性競爭(zheng)(zheng),行(xing)(xing)(xing)業(ye)的(de)價(jia)格(ge)(ge)水平(ping)自2016年起持續下滑。中國五金機電(dian)價(jia)格(ge)(ge)指(zhi)(zhi)(zhi)數(shu)(shu)(shu)顯示,電(dian)線電(dian)纜(lan)行(xing)(xing)(xing)業(ye)價(jia)格(ge)(ge)指(zhi)(zhi)(zhi)數(shu)(shu)(shu)長期(qi)以(yi)來低(di)于(yu)(yu)100,產(chan)品技(ji)術含(han)量低(di)、同質化問(wen)題嚴重(zhong)是(shi)導(dao)致行(xing)(xing)(xing)業(ye)價(jia)格(ge)(ge)持續低(di)迷(mi)的(de)主要原因。但是(shi)隨著疫情(qing)影響減(jian)弱,市(shi)場投資熱情(qing)漸起,加之政策的(de)引導(dao),自2020年11月開(kai)始,價(jia)格(ge)(ge)指(zhi)(zhi)(zhi)數(shu)(shu)(shu)有了(le)明顯的(de)回升。截至2022年12月,我(wo)國電(dian)線電(dian)纜(lan)行(xing)(xing)(xing)業(ye)價(jia)格(ge)(ge)指(zhi)(zhi)(zhi)數(shu)(shu)(shu)為(wei)124.65,已經(jing)遠高于(yu)(yu)前期(qi)高點。

 

注(zhu):價格(ge)指(zhi)數基數2012年6月=100。

 

4、市場規模增速放緩

 

近年來,隨著中(zhong)國電(dian)力、石油、化工(gong)、城(cheng)市軌(gui)道(dao)交(jiao)通、汽車以及造(zao)船等行(xing)(xing)(xing)業(ye)(ye)快速發展和規(gui)模的不斷擴大(da),特別是電(dian)網(wang)改造(zao)加快、特高壓(ya)工(gong)程相繼(ji)投入建設(she),以及全(quan)球電(dian)線電(dian)纜(lan)產品向以中(zhong)國為主(zhu)的亞太地(di)區轉(zhuan)移,中(zhong)國電(dian)線電(dian)纜(lan)行(xing)(xing)(xing)業(ye)(ye)市場規(gui)模迅速壯大(da),電(dian)線電(dian)纜(lan)制造(zao)業(ye)(ye)已經成為電(dian)工(gong)電(dian)器行(xing)(xing)(xing)業(ye)(ye)二十余個(ge)細分行(xing)(xing)(xing)業(ye)(ye)中(zhong)規(gui)模最(zui)大(da)的行(xing)(xing)(xing)業(ye)(ye),占據四(si)分之一的比(bi)重。

 

根據國家統計局的(de)數據,由(you)于(yu)近年(nian)來(lai)我國宏觀經(jing)濟(ji)疲(pi)軟(ruan)和(he)制造(zao)業(ye)(ye)去產能的(de)影(ying)響,電(dian)線電(dian)纜(lan)行(xing)(xing)業(ye)(ye)一度出現規(gui)模下滑,并(bing)在2018年(nian)達到低谷,達到0.99萬億元。隨著我國對新能源等(deng)投資的(de)加快,電(dian)線電(dian)纜(lan)行(xing)(xing)業(ye)(ye)開始緩慢(man)復蘇。2021年(nian)中國電(dian)線電(dian)纜(lan)行(xing)(xing)業(ye)(ye)規(gui)上企業(ye)(ye)銷售收入達1.12萬億元,同(tong)比增(zeng)長3.6%。

 

注:規模以上(shang)企業指營收規模2000萬元以上(shang)的(de)企業。

 

行業競爭格局

 

 

1、區域競爭:國內形成多個電線電纜產業集群

 

從企(qi)(qi)業(ye)(ye)數量區域分布來看,目前(qian)中國電(dian)線(xian)(xian)電(dian)纜企(qi)(qi)業(ye)(ye)主(zhu)要分布于東(dong)部沿海(hai)地(di)區,以河北、江蘇、廣(guang)(guang)東(dong)、浙(zhe)江、山(shan)東(dong)等(deng)省份為主(zhu)。截至2022年12月27日,河北共有相關電(dian)線(xian)(xian)電(dian)纜企(qi)(qi)業(ye)(ye)數4507家,江蘇和廣(guang)(guang)東(dong)分別有3856家和3519家。

 

注(zhu):篩(shai)選邏輯為(wei)名稱、產品(pin)服務和(he)經營范圍中包含了“電(dian)線(xian)電(dian)纜(lan)”的企(qi)業,行業歸類從屬于國民經濟分類的“電(dian)線(xian)、電(dian)纜(lan)、光纜(lan)及電(dian)工器(qi)材制造”。

 

長三(san)角(jiao)地(di)區(qu)(qu)是(shi)我國最(zui)大的(de)(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)生產基地(di),形成了(le)數個(ge)以區(qu)(qu)域大型電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)企(qi)(qi)業(ye)(ye)的(de)(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)企(qi)(qi)業(ye)(ye)集群(qun)(qun)(qun)(qun),如(ru)以寶勝股(gu)份(fen)、上上電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)、智(zhi)慧能源、亨通光電(dian)(dian)(dian)、中天(tian)科技、中辰(chen)電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)等為代(dai)表的(de)(de)(de)江(jiang)蘇(su)企(qi)(qi)業(ye)(ye)集群(qun)(qun)(qun)(qun);以杭電(dian)(dian)(dian)股(gu)份(fen)、萬(wan)馬股(gu)份(fen)等為代(dai)表的(de)(de)(de)浙江(jiang)企(qi)(qi)業(ye)(ye)集群(qun)(qun)(qun)(qun);以太平(ping)洋電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)為代(dai)表的(de)(de)(de)安(an)徽企(qi)(qi)業(ye)(ye)集群(qun)(qun)(qun)(qun);以金龍羽、南洋電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)等企(qi)(qi)業(ye)(ye)為代(dai)表的(de)(de)(de)珠三(san)角(jiao)產業(ye)(ye)集群(qun)(qun)(qun)(qun)。宜興(xing)市(shi)是(shi)我國電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)(lan)(lan)(lan)產業(ye)(ye)最(zui)集中的(de)(de)(de)區(qu)(qu)域之一,區(qu)(qu)域內配套成熟(shu),企(qi)(qi)業(ye)(ye)技術水平(ping)、生產能力和市(shi)場開拓能力均處于全國領先(xian)水平(ping)。

 

2、企業競爭:市場集中度低

 

我國電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)行業競爭激烈,市(shi)場份(fen)(fen)(fen)額較(jiao)分散。2021年,全國電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)行業銷售(shou)收(shou)(shou)入為(wei)(wei)(wei)11154億元,其中(zhong)寶勝股(gu)份(fen)(fen)(fen)的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)業務營業收(shou)(shou)入達406.59億元,市(shi)占(zhan)率為(wei)(wei)(wei)3.65%,排(pai)名第一;遠東股(gu)份(fen)(fen)(fen)和(he)起帆電(dian)(dian)纜(lan)(lan)的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)業務營業收(shou)(shou)入為(wei)(wei)(wei)184.30億元和(he)183.45億元,市(shi)占(zhan)率分別為(wei)(wei)(wei)1.65%和(he)1.64%;其余(yu)企業市(shi)場份(fen)(fen)(fen)額均低于1%。

 

從整體上(shang)看,我國電(dian)(dian)線電(dian)(dian)纜(lan)(lan)行業(ye)(ye)市(shi)(shi)場集中(zhong)度低下,行業(ye)(ye)內多數(shu)企(qi)業(ye)(ye)規(gui)模較小,產品(pin)單(dan)一且多集中(zhong)在中(zhong)低壓(ya)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)領域,因(yin)此中(zhong)低壓(ya)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)產品(pin)同質(zhi)化競(jing)(jing)爭嚴(yan)重。目前,國內大型電(dian)(dian)線電(dian)(dian)纜(lan)(lan)企(qi)業(ye)(ye)、外資企(qi)業(ye)(ye)和合(he)資企(qi)業(ye)(ye)在國內特高(gao)壓(ya)、超高(gao)壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)和高(gao)端(duan)特種(zhong)電(dian)(dian)纜(lan)(lan)如核電(dian)(dian)、海纜(lan)(lan)等領域開(kai)展市(shi)(shi)場競(jing)(jing)爭,在某些細(xi)分市(shi)(shi)場已經形成幾家電(dian)(dian)線電(dian)(dian)纜(lan)(lan)企(qi)業(ye)(ye)寡頭壟斷的競(jing)(jing)爭格局(ju)。

 

行業發展前景及趨勢預測

 

1、發展前景:行業市場規模接近1.6萬億元

 

南網(wang)(wang)電(dian)(dian)(dian)網(wang)(wang)明確(que)提出,“十四(si)五”期(qi)間規劃投資約6700億元,以加快數字電(dian)(dian)(dian)網(wang)(wang)建(jian)設和現代化電(dian)(dian)(dian)網(wang)(wang)進程(cheng),推動(dong)以新能源為主體的新型電(dian)(dian)(dian)力系統構建(jian)。根據國家對電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜主要(yao)應用領(ling)域-電(dian)(dian)(dian)力(新能源、智慧電(dian)(dian)(dian)網(wang)(wang))、軌道交通、航空航天、海洋工程(cheng)等規劃來(lai)看,未來(lai)我國電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜行(xing)業前景向好,行(xing)業產(chan)品升級(ji)趨(qu)勢明顯。預計到2027年,中國電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜行(xing)業規上企業銷售收(shou)入接近1.6萬億元。

 

2、發展趨勢:高端智能化進程將加快

 

“十(shi)四五”期間,國(guo)家將大(da)力(li)(li)提升(sheng)風(feng)電(dian)(dian)(dian)、光(guang)伏發(fa)電(dian)(dian)(dian)規模(mo);提高特(te)高壓輸電(dian)(dian)(dian)通道(dao)利(li)用率,加(jia)快電(dian)(dian)(dian)網基(ji)礎設施智(zhi)(zhi)能(neng)化改(gai)造(zao)和智(zhi)(zhi)能(neng)微電(dian)(dian)(dian)網建設,也因(yin)此對電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的質量提出了新的要求。在(zai)此背景(jing)下,行業內領先企(qi)業將加(jia)大(da)研發(fa)投入、完善研發(fa)體系,行業研發(fa)能(neng)力(li)(li)和技術水平將持續提升(sheng)。同(tong)時,隨著新能(neng)源、高端裝備制(zhi)造(zao)業等領域(yu)的快速崛起(qi),對特(te)高壓、超(chao)高壓電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜和高端特(te)種電(dian)(dian)(dian)纜的需求日益增加(jia),未來電(dian)(dian)(dian)纜行業將加(jia)快高端智(zhi)(zhi)能(neng)化進程(cheng)。
