A Flexible Mathematical Programming Model to Estimate Interregional Input-Output Accounts*
提出并测试了一个数学规划模型，利用国家投入产出表和区域经济数据来估计区域间的产业交易流，能够从高度扭曲的初始估计中恢复真实的区域间贸易模式。
Abstract. This study implements and tests a mathematical programming model to estimate interregional, interindustry transaction flows in a national system of economic regions based on an interregional accounting framework and initial information of interregional shipments. A national input–output (IO) table, regional data on gross output, value-added, exports, imports, and final demand at sector level are used as inputs to generate an interregional IO account that reconciles regional economic statistics and interregional transaction data. The model is tested using data from a multiregional global IO database and shows remarkable capacity to discover true interregional trade patterns from highly distorted initial estimates.
