| 摘要: |
| 关注沿海地区的蓝色碳汇优势，提高绿色全要素生产率，对于沿海城市生态宜居、增强竞 争力有独特而重要的作用。文章基于政府工作报告和百度搜索指数测算蓝色碳汇关注度，利用2011—2022 年中国 53 个沿海城市的面板数据，实证分析蓝色碳汇关注度对沿海城市绿色全要素生产率的作用机制。研究发现： 蓝色碳汇关注度的增加有利于提升沿海城市绿色全要素生产率， 且相较于公众关注，政府对蓝色碳汇关注度的促进作用更为突出；绿色技术创新能力超过门槛值 时，蓝色碳汇关注度对绿色全要素生产率的促进作用将显著增强；蓝色碳汇关注度通过增加绿色 信贷和抑制污水排放提升绿色全要素生产率；南、北方沿海城市蓝色碳汇关注度对绿色全要素生 产率的影响存在差异。研究结论可为沿海城市推动绿色发展提供理论支撑和经验证据。 |

| Abstract: |
| Leveraging the advantages of blue carbon sinks in coastal regions to enhance green total factor productivity
（GTFP）plays a unique and vital role in achieving ecological livability and improving competitiveness in coastal cities． Using government work reports and the Baidu Search Index to measure blue carbon sink attention，this study employs panel data from 53 coastal cities in China from 2011 to 2022 to empirically analyze the impact of blue carbon sink
attention on green total factor productivity．The findings are as follows．（1）An increase in blue carbon sink attention improves GTFP in coastal cities，with government attention exerting a more significant promoting effect compared to public attention．（2）When green technological innovation capacity exceeds a certain threshold，the positive effect of blue carbon sink attention on GTFP is significantly enhanced．（3）Blue carbon sink attention improves GTFP by expanding green credit and reducing wastewater discharge．（4）The promoting effect of blue carbon sink attention on GTFP varies between southern and northern coastal cities．These research findings provide theoretical support and empirical evidence for promoting green development in coastal cities. |
