社会经济统计数据空间化研究进展

A review on the spatial disaggregation of socioeconomic statistical data

社会经济统计数据通常是以各级行政区为单位的汇总数据,它虽然能反映统计单元之间的差异但却不能反映统计单元内部的异质性,在实际应用中,无法满足统计任意区域内的社会经济数据的需求,而社会经济统计数据空间化则是有效解决该问题的一条重要途径。本文对现有社会经济统计数据的空间化方法、社会经济统计数据空间化过程所依赖的辅助数据、现有主要的社会经济空间化数据产品进行了归纳总结,并从空间化方法的制约因素和改进方向、新型辅助数据的探索和多源辅助数据的综合利用、高时空分辨率和高精度数据产品研发3个方面展望了社会经济统计数据空间化的未来发展趋势。研究结果可为社会经济统计数据空间化方法的选择与改进、辅助数据的选择与综合利用、社会经济空间化数据产品的选择与改进提供参考。

Socioeconomic statistical data is usually aggregated in units of administrative regions.The socioeconomic statistical data can reflect the heterogeneity between statistical units,but it cannot reflect the heterogeneity within a statistical unit.The socioeconomic statistical data cannot meet the needs of socioeconomic departments concerned in arbitrary regions.The spatial disaggregation of socioeconomic statistical data is an effective way to solve this problem.This study summarizes the existing methods of spatial disaggregation of socioeconomic statistical data,the auxiliary data used in methods for obtaining spatial disaggregation of socioeconomic statistical data,and the main socioeconomic grid data products.This study also predicts future development trends of the spatial disaggregation of socioeconomic statistical data in three aspects:the constraints and improvement directions of methods,the exploration of new auxiliary data and the comprehensive utilization of multisource auxiliary data,the development of high temporal and spatial resolution and highprecision grid data products.The research results can provide references for the selection and improvement of spatial disaggregation methods of socioeconomic statistical data,the selection and comprehensive utilization of auxiliary data,and the selection and improvement of socioeconomic grid data products.
