我(wo)國(guo)電線(xian)電纜產(chan)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)發展已經(jing)具有較長時間的(de)(de)歷(li)史(shi)，形成了成熟(shu)的(de)(de)產(chan)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)鏈和完整的(de)(de)工業(ye)(ye)(ye)(ye)(ye)(ye)(ye)體(ti)系，參與(yu)競爭的(de)(de)企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)數量(liang)眾多(duo)，2018年我(wo)國(guo)電線(xian)電纜行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)規上企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)數量(liang)已經(jing)達(da)到了4049家，企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)集中(zhong)在華(hua)東地區。我(wo)國(guo)線(xian)纜行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)呈現出(chu)以大型企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)為(wei)主，外(wai)資企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)和中(zhong)小企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)為(wei)輔的(de)(de)競爭格局。從行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)整體(ti)來看，我(wo)國(guo)企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)的(de)(de)產(chan)品主要(yao)集中(zhong)在中(zhong)低端市場，行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)集中(zhong)度低，中(zhong)小企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)占比 95%以上，前十名企(qi)(qi)(qi)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)僅占國(guo)內市場份額的(de)(de) 7%至 10%。

目前(qian)，我國(guo)墻壁(bi)開關(guan)插(cha)(cha)座(zuo)行業(ye)參(can)與者(zhe)眾多，墻壁(bi)開關(guan)插(cha)(cha)座(zuo)行業(ye)從業(ye)企(qi)業(ye)已達2000家(jia)，形成了(le)廣東、江浙、北京(jing)三大生(sheng)產基地。以(yi)西(xi)門子、松(song)下(xia)為代表的外(wai)資品(pin)牌通過并購(gou)國(guo)內(nei)(nei)企(qi)業(ye)或設立銷售代理的方(fang)式(shi)進(jin)入市場(chang)，形成了(le)跨國(guo)公司與國(guo)內(nei)(nei)本土企(qi)業(ye)并存的競(jing)爭格局。市場(chang)主(zhu)要國(guo)外(wai)競(jing)爭品(pin)牌有西(xi)門子、施耐德、羅格朗、西(xi)蒙與松(song)下(xia)；主(zhu)要國(guo)內(nei)(nei)本土競(jing)爭品(pin)牌有公牛(niu)、正泰、德力西(xi)、歐普、飛雕與鴻雁。

目前我國插(cha)座生產(chan)(chan)企業超(chao)過了1500家，其中市(shi)場知(zhi)名品牌僅有20個(ge)左右，公牛品牌插(cha)座產(chan)(chan)品占據最(zui)大的市(shi)場份額，約達20%，插(cha)座生產(chan)(chan)企業依然(ran)以(yi)中小企業為主。從(cong)市(shi)場需(xu)(xu)求上看(kan)，消(xiao)費者(zhe)不(bu)再僅僅滿足(zu)于(yu)產(chan)(chan)品的質量(liang)，開始重視(shi)產(chan)(chan)品的外觀和功能，用(yong)電安全(quan)更是成(cheng)為消(xiao)費者(zhe)的根本需(xu)(xu)求。
