摘　　要：基于2013—2020年中国25个省份的面板数据,采用基准回归模型、门槛模型和工具变量法,实证分析产业集聚对中国林产工业碳排放强度的影响机制。结果表明:产业集聚与林产工业碳排放强度呈现显著的倒“U”型关系,初期产业集聚度的上升会加剧碳排放,但当集聚水平跨越门槛值后逐步降低。异质性分析表明,相较于其他行业,造纸行业因资源依赖度高、能耗大,碳排放强度对产业集聚水平更敏感;由于不同地区的资源禀赋和经济结构存在差异,西部和东北地区的产业集聚与林产工业碳排放强度呈现“U”型关系。此外,产业集聚带来的技术创新和研发投入能够显著降低碳排放强度。据此,建议结合区域林产工业实际情况,推进林产工业产业集群建设,提升区域经济发展质量和优化产业结构;构建低碳技术创新体系,推动技术突破和产学研合作;促进区域联盟合作,提高产业链效率与竞争力。Based on the panel data of 25 provinces in China from 2013 to 2020,this article uses the benchmark regression model,the threshold model and the instrumental variable method to empirically analyze the impact of industrial agglomeration on the carbon emission intensity of China’s forest products industry.The results show that there exists a significant inverted U-shaped relationship between industrial agglomeration and carbon emission intensity of forest product industry,and that the increase of agglomeration degree aggravates carbon emission in the initial stage before it gradually decreases after crossing the threshold value.Heterogeneity analysis shows that compared with other industries,the carbon emission intensity of paper industry is more sensitive to the agglomeration level due to its high resource dependence and high energy consumption.Due to the different resource endowments and economic structures in different regions,the industrial agglomeration in the western and northeastern regions shows a U-shaped relationship with the carbon emission intensity of the forest industry.Additionally,technological innovation and R&D investment brought about by industrial agglomeration can significantly reduce carbon emission intensity.Therefore,it is suggested to strengthen the construction of industrial cluster of forest products industry and promote regional economic development and industrial structure optimization according to the actual situation of regional forest products industry.Furthermore,it is necessary to build a low-carbon technological innovation system,facilitate technological breakthroughs,foster industry-university-research cooperation,and promote regional alliances to improve the efficiency and competitiveness of industrial chains.
