从近十年我国共享充电宝相关(guan)企业的年注册量变化来看,企查查数(shu)据显示,2017年注册量为15家,同比增长114.3%。2019年行业进入高速发展期,注册量涨至68家,同比增长172.0%。2020年注册量达到十年来高的84家,同比增长23.5%。
据(ju)新华每日电讯发布的消息,共(gong)享(xiang)单车起步价已(yi)从初(chu)的每小时0.5元(yuan)、1元提升(sheng)至(zhi)半小时1.5元(yuan),“单(dan)车(che)价格(ge)逐步(bu)超越公交车(che)”;共享充(chong)电宝涨(zhang)幅更(geng)惊(jing)人,已(yi)从(cong)之(zhi)前半小(xiao)时免费或每小(xiao)时1元,猛涨至每小时4元,如果一(yi)时间难以归还还会(hui)面临(lin)更高的(de)单(dan)日费用。
近(jin)一两年来,不同品牌的共享充(chong)电宝悄(qiao)然集(ji)体涨价(jia),从(cong)初的每小时1元、半小时免(mian)费的“亲(qin)民”价格,到现在平均每(mei)小时需花费3至4元(yuan),让不少(shao)消费者直呼“用不(bu)起(qi)”。
据企查(cha)查(cha)数据显(xian)示,目前我国共(gong)有共(gong)享充电宝企业(ye)213家,2020年全年新注(zhu)册84家,同比增长(zhang)23.5%。
从近(jin)十(shi)年我(wo)国共享充电宝(bao)相(xiang)关企业的(de)年注册量变化(hua)来看,企查查数据显示,2017年注册量(liang)为15家,同比增(zeng)长114.3%。2019年行业进入(ru)高(gao)速发展期,注册(ce)量涨至(zhi)68家,同比增长172.0%。2020年注册(ce)量达到十年来高(gao)的(de)84家,同比增长23.5%。
从注册资本分布来看,企(qi)(qi)查查数据显示,我国共享(xiang)充电(dian)宝相(xiang)关(guan)企(qi)(qi)业(ye)中共有39%的企业注册(ce)资(zi)本在100-500万之间(jian),注(zhu)册资本(ben)在(zai)100万之内的(de)占比36%,而其他(ta)的25%的企业(ye)注(zhu)册(ce)资(zi)本(ben)在500万以上。
从(cong)省(sheng)份分布来看(kan),企查查数据显(xian)示,我国共享充电宝相关企业数量多的是广(guang)东、贵州、陕西等地区。其中,广(guang)东省(sheng)目前以90家企业(ye)排名,贵州省以16家企业排名第二,陕西以11家企业排名(ming)(ming)第三。此(ci)外,云(yun)南和安(an)徽(hui)并(bing)列第四名(ming)(ming),企业数(shu)量均为(wei)9家(jia)。
从城(cheng)市(shi)分布来看,企查(cha)(cha)查(cha)(cha)数据显示,深圳市(shi)以72家(jia)企(qi)业数量(liang)高居位,遥(yao)遥(yao)领先于其他城市,占(zhan)比全国总(zong)量(liang)的(de)33.9%。西安(an)、贵(gui)阳(yang)则排名二三(san)位,企业数(shu)量分(fen)别(bie)为(wei)8家(jia)和5家(jia)。此外,宜昌、合(he)肥、昆明、衡(heng)阳、九江、济南(nan)同样跻身(shen)前十。
但(dan)靠涨价盈(ying)利,绝非不是长久(jiu)之计。
共享(xiang)充电宝价格与新注册(ce)企业增长的同时,相关企业进入资(zi)本市场的步伐也(ye)在加快。
3月13日,怪兽充(chong)电(dian)正式向美国证券交(jiao)易委员(yuan)会递(di)交(jiao)招(zhao)(zhao)股文件,拟在纳斯达(da)克上市(shi)。招(zhao)(zhao)股书显示,2020年怪兽(shou)充电营(ying)收28.094亿元(yuan),其中充电(dian)宝收入为27.115亿(yi)元,占比高达到96.5%。但在利(li)润方面,2020年因(yin)受疫情影(ying)响(xiang),用户(hu)需求锐(rui)减,全年净(jing)利(li)润仅为7540万元,净利率仅2.7%。
此(ci)外,另一家共享(xiang)充电宝企业小电科技也在冲刺(ci)IPO。2020年(nian)6月(yue),小电(dian)科技与浙江(jiang)证(zheng)券签署了(le)上(shang)市(shi)辅导协议,拟在创(chuang)业(ye)板(ban)挂牌上(shang)市(shi)。新消息(xi)显示,小电(dian)科技已进入第二轮(lun)辅导期(qi),预计于(yu)今年三季度(du)登陆创(chuang)业(ye)板(ban)

一度成为(wei)风口的共(gong)(gong)享充电(dian)宝(bao)领域经过资(zi)本角逐、洗牌(pai)调整及(ji)模式(shi)探(tan)索后,开始(shi)进入提价(jia)(jia)阶(jie)段。北京(jing)商报(bao)记者(zhe)近日发现,共(gong)(gong)享充电(dian)宝(bao)品(pin)牌(pai)街电(dian)常规使用的计费(fei)标准从(cong)每小时1元翻倍涨价(jia)(jia)为(wei)每小时2元。同(tong)时,多个(ge)共(gong)(gong)享充电(dian)宝(bao)品(pin)牌(pai)也都实(shi)施了涨价(jia)(jia)。业(ye)内(nei)人士分析认(ren)为(wei),价(jia)(jia)格上涨背后是企(qi)业(ye)
