加速产业集聚,构建产业集群已成为促进地方经济快速发展的重要途径。制造业集聚程度与环境之间究竟是什么关系?利用我国制造业分行业1999—2012年共14年的面板数据,构建多重门槛回归模型考察制造业产业集聚的不同阶段对环境的影响,结果表明:我国制造业分行业在产业集聚的不同阶段对环境的影响不同,目前我国环境污染指标(工业的排放量)与制造业聚集水平的关系是处于N型曲线的两个转折点之间。
Accelerating industrial agglomeration and building industrial clusters have become important ways to promote the rapid development of local economies. What is the relationship between the level of manufacturing concentration and the environment? Using the panel data of China's manufacturing industry for a total of 14 years from 1999 to 2012, a multi-threshold regression model was constructed to examine the impact of different stages of manufacturing industry agglomeration on the environment. The results showed that : China's manufacturing sub-sectors have different impacts on the environment at different stages of industrial agglomeration. At present, the relationship between China's environmental pollution indicators (industrial emissions) and the level of manufacturing concentration is between the two turning points of the N-type curve.
