能源效率视域下集聚经济的空间衰减研究

Research on Spatial Attenuation of Agglomeration Economy from the Perspective of Energy Efficiency

在文献综述的基础上,使用固定效应模型,研究空间集聚对制造行业能源消费行为的影响,结果表明,空间集聚能显著降低企业的能源强度。就全国总体而言,当研究区域的半径扩大时,集聚的调节作用呈现空间衰减趋势。分区域研究发现,东部地区集聚效应的衰减与全国总体趋势一致;中部地区在60公里范围内呈空间增强趋势;西部地区的衰减趋势较为平缓,但总体仍呈下降趋势。异质性分析表明,集聚的节能作用对外资企业和私营企业更明显。

Based on the literature review,a fixed effects model was used to study the impact of spatial agglomeration on energy consumption behavior in the manufacturing industry.The results showed that spatial agglomeration can significantly reduce the energy intensity of enterprises.Overall,as the radius of the research area expands,the moderating effect of agglomeration shows a spatial decay trend.Regional studies have found that the attenuation of agglomeration effects in the eastern region is consistent with the overall trend nationwide;the central region shows a spatial strengthening trend within a range of 60 kilometers;the attenuation trend in the western region is relatively flat,but overall it still shows a downward trend.Heterogeneity analysis shows that the energy-saving effect of agglomeration is more significant for foreign-funded enterprises and private enterprises.
