城市群空间功能分工对经济活力的影响

The Influence of Spatial Function Division of Urban Agglomeration on Economic Vitality

文章以中国七大城市群为样本,利用计量模型从线性和非线性视角研究城市群空间功能分工对经济活力的影响,并探究非线性影响的异质性。结果表明:从线性角度而言,城市群空间功能分工对经济活力存在显著正向影响;从非线性角度而言,城市群空间功能分工对经济活力存在先抑制后促进的“U”型影响,且中心城市的这一影响作用大于外围城市。鉴于此,文章有针对性地提出了推动城市群内产业转移、细化城市群空间功能分工、促进城市群间良性合作的政策建议。

Taking seven major urban agglomerations in China as samples,this paper uses econometric models to study the impact of spatial function division of urban agglomerations on economic vitality from linear and nonlinear perspectives,and to explore the heterogeneity of nonlinear effects.The results show that:from a linear perspective,the spatial function division of urban agglomeration has a significant positive impact on economic vitality;From a non-linear perspective,the spatial function division of urban agglomeration has a"U"shaped impact on economic vitality,which first inhibits and then promotes,and the impact of the central city is greater than that of the peripheral cities.In view of this,this paper puts forward policy suggestions to promote industrial transfer within urban agglomerations,refine the division of spatial functions of urban agglomerations,and promote benign cooperation among urban agglomerations.
