摘要

基于多区域输入-输出（MRIO）表进行网络分析的研究人员无法避免深入讨论的过滤问题，这意味着识别最重要和最重要的贸易联系。什么是合适的过滤方法的问题仍然存在。本文在评估现有MRIO表过滤方法的基础上，扩展了现有的讨论，并带来了新的见解。主流文献中的六种过滤方法被确定为相关的，并在已发布的MRIO表上进行了测试：EORA26和EXIOBASE。案例研究验证了这一结果。评估表明，基于Weaver–Thomas指数的容忍极限方法和滤波器是最具限制性的。Leontief滤波器和基于整体精度的滤波器可以部分推荐。对绝对交易价值和平均交易的筛选可以被推荐为“好”方法。

Filter methods for MRIO tables: an evaluation

Researchers who deal with network analysis based on multi-regional input–output (MRIO) tables cannot avoid the intensively discussed issue of filtering, which means identification of the most important and significant trade connections. The question of what is an appropriate filter method remains. This paper expands the existing discussion and brings new insight based on the evaluation of existing filter methods for MRIO tables. Six filter methods from the prevailing literature are identified as relevant and tested on the published MRIO tables: EORA26 and EXIOBASE. The results are verified by a case study. The evaluation shows that the Tolerable Limit approach and filter based on the Weaver–Thomas Index are the most restrictive. The Leontief filter and the filter based on holistic accuracy can be partially recommended. The filter on absolute trade values and average transactions can be recommended as ‘good’ methods.

期刊介绍： Economic Systems Research is a double blind peer-reviewed scientific journal dedicated to the furtherance of theoretical and factual knowledge about economic systems, structures and processes, and their change through time and space, at the subnational, national and international level. The journal contains sensible, matter-of-fact tools and data for modelling, policy analysis, planning and decision making in large economic environments. It promotes understanding in economic thinking and between theoretical schools of East and West, North and South.
