摘要
制造业和生产性服务业协同集聚已成为降低碳排放进而实现双碳目标的重要推手。基于30个省市2008—2019年的数据,运用双向固定效应模型实证分析制造业和生产性服务业协同集聚对碳排放强度的影响及行业异质性,结果表明:产业协同集聚对碳排放强度影响呈倒U型,即具有先促进后抑制的作用,当产业协同集聚度低于3.142,产业协同集聚会提高碳排放强度;当产业协同集聚度跨过拐点值3.142,产业协同集聚会降低碳排放强度。基于行业异质性,高端产业协同集聚和低端产业协同集聚都能降低碳排放强度,但高端产业协同集聚的碳减排效果要优于低端产业协同集聚。
The co-agglomeration of manufacturing and producer services has become an important driver to reduce carbon emissions and achieve the dual carbon goal. Based on the data of 30 provinces and cities from 2008 to 2019, the two-way fixed effect model is used to empirically analyze the impact of co-agglomeration of manufacturing and producer services on carbon emission intensity and industry heterogeneity. The results show that the impact of industrial co-agglomeration on carbon emission intensity is inverted U-shaped, that is, it can promote first and then inhibit. When the degree of industrial co-agglomeration is lower than 3. 142, the industrial co-agglomeration can improve carbon emission intensity;When the industrial co-agglomeration degree crosses the inflection point value of 3. 142, the industrial co-agglomeration will reduce the carbon emission intensity. Based on industry heterogeneity, both high-end industrial collaborative agglomeration and low-end industrial collaborative agglomeration can reduce carbon emission intensity, but the carbon emission reduction effect of high-end industrial collaborative agglomeration is better than that of low-end industrial collaborative agglomeration.
