近幾年，日本的企業活力不足，但是有(you)(you)多年的品牌優(you)勢，中國(guo)電容跟(gen)他們還有(you)(you)差距，但是差距在(zai)逐漸縮小。

日本公司正在逐步退出中低端市(shi)場，另一方(fang)面由于汽車電(dian)(dian)子、服務器等帶動鋁電(dian)(dian)解電(dian)(dian)容(rong)需求，日系廠商專注于附加值較高的汽車、、及(ji)工(gong)業領(ling)域，釋出消(xiao)費類電(dian)(dian)子電(dian)(dian)容(rong)器和(he)材料市(shi)場領(ling)域給非日系廠商，需求逐步向大(da)陸(lu)及(ji)臺(tai)灣轉移。

根據臺(tai)灣中(zhong)時電子(zi)報新聞，目前(qian)(qian)臺(tai)系(xi)鋁(lv)(lv)電解(jie)電容(rong)器廠(chang)(chang)認為，2018年高中(zhong)低壓(ya)鋁(lv)(lv)箔(bo)均可(ke)能短(duan)缺(que)，目前(qian)(qian)鋁(lv)(lv)箔(bo)供(gong)不應求，預估(gu)中(zhong)國大陸11月、12月鋁(lv)(lv)箔(bo)短(duan)缺(que)影(ying)響程(cheng)度(du)在15%-25%。鋁(lv)(lv)箔(bo)材料的(de)短(duan)缺(que)，導致下游(you)鋁(lv)(lv)電容(rong)等被動元器件再(zai)掀漲(zhang)價風波。從拉貨時程(cheng)來看，受到日(ri)(ri)系(xi)電容(rong)器廠(chang)(chang)商(shang)(shang)銷售策(ce)略(lve)改變以及中(zhong)國上游(you)鋁(lv)(lv)箔(bo)材料供(gong)不應求等因素影(ying)響，日(ri)(ri)系(xi)電容(rong)器廠(chang)(chang)商(shang)(shang)交貨時程(cheng)，已經從原先(xian)的(de)6周(zhou)拉長到12周(zhou)，部分日(ri)(ri)系(xi)電容(rong)器廠(chang)(chang)商(shang)(shang)交貨時程(cheng)甚至達到半年。
