碳锁定的空间非均衡性及动态演进分析——以江苏为例

Analysis on Spatial Imbalance and Dynamic Evolution of Carbon Lock-in: Taking Jiangsu Province as an Example

从城市尺度出发,以江苏省13个地级市为研究对象,利用泰尔指数及其嵌套分解方法、空间自相关法探究江苏碳锁定的空间非均衡及动态演进特征。结果显示:江苏碳锁定分布具有明显的空间非均衡性,城市之间发展不平衡,具有明显的区域差异特征,泰尔指数由高到低依次为苏南地区、苏中地区和苏北地区,并且区内差异的贡献率远大于区间差异的贡献率,三大地区内部发展的非均衡是江苏碳锁定产生差异的主要动因。江苏各城市碳锁定状况存在空间关联特征,空间发展格局集中性不断上升,马太效应有所增强。

This paper uses the Thiel index and its nested decomposition method and spatial autocorrelation method to explore the spatial imbalance and dynamic evolution characteristics of carbon lock-in in 13 prefecture level cities in Jiangsu Province.The results show that the carbon lock-in distribution of Jiangsu Province has obvious spatial imbalance,the developments of cities are unbalanced,and there are obvious regional differences.The Theil index from high to low is southern Jiangsu,central Jiangsu and northern Jiangsu,and the contribution rate of regional differences is far greater than that of interval differences.The imbalance of the internal development of the three regions is the main reason for the difference of carbon lock-in in Jiangsu Province.There are spatial correlation characteristics in the carbon lock-in status of cities in Jiangsu Province,the concentration of spatial development pattern is rising,and the Matthew effect is enhanced.
