Can Carbon Emission Permit Trade Policy Promote Green Technology Innovation in Advanced Manufactur⁃ing Enterprises?

碳排放权交易政策是促进制造业企业绿色创新的重要内容。选取2010—2021年碳排放权交易试点地区A股上市公司数据,运用双重差分模型考察碳排放权交易政策对先进制造业企业绿色技术创新的影响。研究发现:碳排放权交易政策对先进制造业企业的绿色技术创新具有显著促进作用,但是当企业债务融资成本更高时,碳交易政策对先进制造业企业绿色技术创新的促进作用有所降低;企业无形资产越多,碳交易政策对其绿色技术创新的促进作用越明显。相较于小型企业、低竞争度市场中企业,碳交易政策对大型企业、高竞争度市场中企业的绿色技术创新具有更明显的促进作用。
