系统重心迁移的贡献度分解方法

Contribution Decomposition Approach to A System'S Gravity Movement

社会经济系统的重心迁移轨迹可以刻画系统空间演化的发展方向和平衡问题。为分析重心迁移的主导因素,发现并指出了简单分解、方差分解和微分分解等常用的贡献度分解方法在重心法研究中的不适用性及其原因,提出了一种基于夏普里值的、适用于重心法的分解方法。并用中国经济重心迁移对该方法做了验证。

Gravity moment of a social and economic system can describe its spatial evolution and balance.Since general contribution decomposition approaches,based on simple,variance and differential principle respectively,are not suitable in gravity centre method analysis,we propose a new decomposition approach based on Shapley Value.Gravity of China＇s economy is analyzed based on this decomposition approach as an example.
