摘要
本文考察产业集聚及其不同集聚模式对企业减排的影响。研究表明:产业集聚显著降低了企业污染排放强度,且这主要是专业化集聚带来的,多样化集聚的影响并不显著。在加入产业集聚二次项和三次项后并未发现现有宏观数据得到的非线性关系的存在,突出了从微观视角理解集聚减排效应的必要性。深入集聚外部性,通过专业化集聚释放的劳动力蓄水池、中间投入共享和知识溢出三个外部性降低中间品价格、改善企业生产率、提高企业污染处理技术水平是产业集聚实现企业减排的重要机制。
This study investigates the influence of industrial agglomeration and its different agglomeration modes on firm emission reduction. The results show that industrial agglomeration significantly reduces firm emission intensity, which is mainly caused by specialized agglomeration. After adding industrial agglomeration’s secondary and tertiary items, the non-linear relation obtained from existing macro data is not found. Probing into agglomeration externalities, reducing input price, improving firm productivity, and upgrading firm pollution treatment technology are the important mechanisms of industrial agglomeration to reduce firm emission intensity through the three externalities of labor pooling, input sharing and knowledge spillovers generated by specialized agglomeration.
