  • 2025年,太阳能、电动汽车及其他清洁能源技术对中国经济增长的贡献已超过三分之一,并拉动超过九成的投资增长。 中国清洁能源行业产值在2025年达到创纪录的15.4万亿元人民币(约合2.1万亿美元),约占国内生产总值(GDP)的11.4%,该数字相当于巴西或加拿大的经济规模。 Carbon Brief基于官方数字、行业数据及分析师报告进行的最新分析显示,2022年至2025年间,中国清洁能源行业的实际规模几乎翻了一番;若将其视为一个独立经济体,其规模可位列全球第八。 该分析的其他主要成果包括: 清洁能源行业支撑中国实现了“5%左右”的GDP增长目标,若排除清洁能源行业,2025年GDP实际增速仅为3.5%。 清洁能源产业的扩张速度持续快于整体经济,其年增长率从2024年的12%提升至2025年的18%。 电动汽车、电池和光伏“新三样”仍是中国清洁能源经济贡献的核心,创造了约三分之二的增加值,并吸纳了一半以上的行业投资。 2025年,中国在清洁能源领域的投资达7.2万亿元人民币(约1万亿美元),约为同期化石燃料开采与煤电投资(2600亿美元)的四倍。 尽管2025年清洁能源技术出口保持了快速增长,但对中国企业而言,国内市场在价值规模上仍显著大于出口市场。 这些投向清洁能源制造业的资金,代表着对中国乃至全球能源转型的重大押注,也为政府和企业保持这一发展势头提供了动力。 然而,未来的长期走势仍然存在不确定性,尤其是在太阳能领域。受136号文件下的新定价机制影响,太阳能发电装机增速已有所放缓,而中央政府设定的相关目标也明显低于近几年的实际扩张水平。 如果放缓趋势持续下去,这些产业或将从经济增长的驱动力转变为拖累因素,同时加剧工业领域的“产能过剩”问题,并进一步恶化国际贸易摩擦。 但即便中央政府对清洁能源未来五年的目标设定较为谨慎,地方政府和国有企业的规划与投资力度,仍有可能推动清洁能源产业继续实现显著增长。 本文在此前对2023年和2024年清洁能源经济贡献分析的基础上进行了更新。 清洁能源行业表现优于整体经济 中国的清洁能源经济持续高速增长,远超整体经济增速。这意味着它对年度经济增长的贡献尤为显著。 下图显示,2025年,清洁能源技术贡献了中国超过三分之一的GDP增量,并推动了超过90%的新增投资增长。 中国各行业对投资(左)与整体GDP(右)增长的贡献,单位:万亿元。来源:能源与清洁空气研究中心(CREA)为Carbon Brief所作分析。 2022年,中国清洁能源经济规模约为8.4万亿元人民币(1.2万亿美元)。到2025年,这一规模几乎翻了一番,达到15.4万亿元人民币(2.1万亿美元)。 这一体量相当于巴西或加拿大的经济总量,使中国的清洁能源产业堪比全球第八大经济体,产值约为世界第四大经济体印度经济总量的一般,也大致相当于美国加利福尼亚州经济规模的一半。 由于清洁能源产业持续跑赢整体经济,其在中国经济中的占比也在不断上升,从2022年占中国GDP的7.3%上升至2025年的11.4%。 中国清洁能源行业对国内生产总值(GDP)的贡献占比,%。来源:能源与清洁空气研究中心(CREA)为Carbon Brief所作分析。 如果没有清洁能源行业,中国2025年的GDP增速将仅为3.5%,因此,在经济稳定增长为中国首要目标之一的2025年,清洁能源做出了至关重要的贡献。 下表按行业和活动进行了详细分类。 电动汽车和电池是GDP增长的最大驱动力 2024年,电动汽车和太阳能是最大的增长驱动力。而到了2025年,电动汽车和电池则占据了主导地位,合计贡献了44%的经济效益,以及清洁能源行业一半以上的增长。这主要得益于产出和投资的同步强劲增长。 在未剔除通胀因素的名义GDP口径下,电动汽车的贡献甚至更为突出。这是因为电动汽车价格同比保持相对稳定,而整体经济仍处于通缩环境中。同时,电池制造投资在2024年下滑后于2025年出现反弹。 下图展示了电动汽车和电池的主要贡献,既反映了清洁能源经济的整体规模,也显示了各子行业对年度增量的具体贡献情况。 2022-2025年中国清洁能源行业对国内生产总值(GDP)及其增长的贡献,单位:万亿元。来源:能源与清洁空气研究中心(CREA)为Carbon Brief所作分析。 第二大子行业是清洁能源发电、输电和储能,在2025年占清洁能源对GDP贡献的40%,并贡献了清洁能源产业当年约30%的增长。 在电力领域内部,最主要的增长动力来自风电和太阳能发电装机投资的扩大,以及风电和太阳能发电量的增长;其次是太阳能设备及材料的出口。 作为2022–2023年的重要增长引擎,太阳能组件产业链投资在2025年连续第二年下降,这与政府遏制产能过剩和行业“非理性”价格竞争的政策导向一致。 此外,铁路运输约占清洁能源行业总经济产出的12%,但其同比增长相对温和,2025年其营业收入增长3%,投资增长6%。 需要指出的是,国际能源署(IEA)在其《世界能源投资报告》中估计,中国2025年清洁能源投资为 6270亿美元,而化石能源投资为 2570亿美元。 在采用与IEA一致的行业口径进行测算时,本研究对2025年中国清洁能源投资的估计为 4300亿美元,低于IEA的数值。而本文中所呈现的1万亿美元清洁能源投资总规模,并非源于更激进的单项假设,而是由于纳入了更为广泛的产业和活动范围,超出了IEA报告所覆盖的口径。 电动汽车和电池 2025年,电动汽车与动力电池成为中国清洁能源经济中最大的贡献部分,约占清洁能源行业总值的44%。 其中,纯电动汽车和插电式混合动力汽车的生产在价值规模和当年增长贡献两方面均居首位,产量同比增长29%。排在其后的是电动汽车制造领域的投资,在2024年增速放缓后,2025年投资规模同比增长 18% 电池制造投资在2024年出现下滑后也迎来反弹,这主要得益于电池新技术的涌现以及国内外市场的强劲需求。电池制造投资同比增长35%,达到2770亿元人民币。 到2025年底,电动汽车在全国汽车保有量中的占比预计达到12%,高于一年前的 9%,而在五年前这一比例还不足 2%。 在新车销售中,电动汽车占比进一步提升至 48%,高于2024年的 41%,其中乘用车电动汽车渗透率已突破50%。2025年11月,电动汽车在当月汽车总销量中的占比更是首次突破 60%,并持续成为拉动整体汽车销量增长的主要动力,如下图所示。 中国燃油车与电动车产量,单位:百万辆。电动车包含纯电动车及插电式混合动力车。数据来源:中国汽车工业协会,经Wind金融终端汇总整理。 […]
