碳排放主要源于微观企业的生产经营活动,双碳目标最终实现要依靠企业低碳转型、降耗减碳的实际行动。为了解企业低碳转型现状和金融支持情况,本文通过线上问卷调查获取了1472家企业有效问卷,并对54家省重点排放企业、相关政府部门和金融机构进行实地走访。结果表明:一是企业普遍对双碳背景下的低碳转型冲击认知不足,观望情绪严重。二是受碳市场约束不强,技术、人才制约等多因素影响,企业低碳转型动力不足。三是绿色金融需求不足与供给不充分并存,金融支持绿色发展成效并未充分显现,环境数据获取、组织制度安排、绿色金融人才等业务基础存在短板。为此,建议强化顶层设计,引导稳定企业预期;加强绿色金融产品和服务创新;夯实基础工作,完善政策保障。
