A Note on Adjusting National Input‐Output Data for Regional Table Construction
比较了四种区域表构建基础数据的方法，发现Jackson和Comer（1993）的表格分解与调整方法优于未调整的基准表、价格更新基准表和汇总年度更新表。
Regional analysts face a trade‐off between timeliness and detail of commodity‐industry data. The trade‐off exists because the Bureau of Economic Analysis national aggregated annual update tables are published for years more recent than those for which the disaggregated benchmark accounts are available. Conventional wisdom holds that regionalization should precede aggregation, so a disaggregated foundation table is preferred to an aggregation of that same table. This paper shows that the Table Disaggregation and Adjustment (TDA) method of Jackson and Comer (1993) produces a better foundation for regionalization than an unadjusted benchmark, price‐updated benchmark, or aggregated annual update table.
