摘要

本文建立了一个统计框架,利用卫星夜间灯光(DN)数据来增强官方GDP测量,并给出了DN与GDP之间的非线性替代关系。本文采用人口加权变异系数下的二维分解方法,利用DN代替GDP对中国区域发展不平衡进行测度。该方法使我们能够在提出的框架下分析DN分量对区域内和区域间不平等的贡献,我们可以得出结论,区域间的不平衡而不是区域内的不平衡是中国IRD影响全国的主要原因。

Measuring the Imbalance of Regional Development from Outer Space in China
Abstract We develop a statistical framework to use the data of night-time-lights (DN) from satellite to augment official GDP measures, and a non-linear substitution relationship between DN and GDP is given. In this paper, we take advantage of DN instead of GDP to measure the imbalance of regional development (IRD) in China by using the method of bi-dimensional decomposition under the population-weighted coefficient of variation. The method enables us to analyze the contributions of DN components to within-region and between-regions inequality under the framework which has been proposed, we can get the conclusion that the imbalance between-regions rather than within-region is the main reason for the influence of IRD for the whole country in China.
