我國電(dian)線(xian)電(dian)纜產業(ye)(ye)(ye)(ye)發(fa)展已經(jing)(jing)具有(you)較長時間的歷史，形成了(le)成熟的產業(ye)(ye)(ye)(ye)鏈和完整的工業(ye)(ye)(ye)(ye)體(ti)(ti)系，參與(yu)競爭的企(qi)業(ye)(ye)(ye)(ye)數量眾多，2018年我國電(dian)線(xian)電(dian)纜行(xing)(xing)業(ye)(ye)(ye)(ye)規上企(qi)業(ye)(ye)(ye)(ye)數量已經(jing)(jing)達到了(le)4049家，企(qi)業(ye)(ye)(ye)(ye)集(ji)中在華東地區。我國線(xian)纜行(xing)(xing)業(ye)(ye)(ye)(ye)呈現出以(yi)大型企(qi)業(ye)(ye)(ye)(ye)為主(zhu)，外資企(qi)業(ye)(ye)(ye)(ye)和中小企(qi)業(ye)(ye)(ye)(ye)為輔的競爭格(ge)局。從行(xing)(xing)業(ye)(ye)(ye)(ye)整體(ti)(ti)來看，我國企(qi)業(ye)(ye)(ye)(ye)的產品(pin)主(zhu)要集(ji)中在中低端市場(chang)，行(xing)(xing)業(ye)(ye)(ye)(ye)集(ji)中度低，中小企(qi)業(ye)(ye)(ye)(ye)占比 95%以(yi)上，前(qian)十(shi)名企(qi)業(ye)(ye)(ye)(ye)僅占國內(nei)市場(chang)份額的 7%至 10%。

目前，我國墻(qiang)壁開關插座行業(ye)(ye)參與(yu)者眾多，墻(qiang)壁開關插座行業(ye)(ye)從業(ye)(ye)企(qi)業(ye)(ye)已達2000家，形(xing)成了廣東(dong)、江浙、北(bei)京三大生產基地(di)。以西(xi)門子、松下為代表的(de)(de)外(wai)資品牌(pai)通(tong)過并購國內企(qi)業(ye)(ye)或設立銷售代理的(de)(de)方(fang)式進入市(shi)場，形(xing)成了跨國公(gong)司與(yu)國內本土企(qi)業(ye)(ye)并存的(de)(de)競(jing)爭(zheng)(zheng)格局。市(shi)場主要(yao)國外(wai)競(jing)爭(zheng)(zheng)品牌(pai)有西(xi)門子、施(shi)耐德、羅(luo)格朗、西(xi)蒙與(yu)松下；主要(yao)國內本土競(jing)爭(zheng)(zheng)品牌(pai)有公(gong)牛、正泰、德力西(xi)、歐普、飛(fei)雕與(yu)鴻雁。

目(mu)前我國(guo)插(cha)座生產(chan)(chan)企(qi)(qi)業(ye)超過了1500家，其中(zhong)市場知名品牌(pai)僅有20個(ge)左右，公牛品牌(pai)插(cha)座產(chan)(chan)品占據最(zui)大的(de)(de)市場份額(e)，約(yue)達20%，插(cha)座生產(chan)(chan)企(qi)(qi)業(ye)依然以(yi)中(zhong)小(xiao)企(qi)(qi)業(ye)為主(zhu)。從(cong)市場需求上看，消(xiao)費(fei)者不(bu)再僅僅滿足于(yu)產(chan)(chan)品的(de)(de)質量，開始重視產(chan)(chan)品的(de)(de)外觀和(he)功能，用電安全更是成為消(xiao)費(fei)者的(de)(de)根本需求。
