Improved Estimation of Regional Input-Output Tables Using Cross-regional Methods

JIANG X., DIETZENBACHER E. and LOS B. Improved estimation of regional input-output tables using cross-regional methods, Regional Studies. Many regional input-output tables are estimated by means of non-survey methods. Often, information on the margins of the projected table is complemented by full information on intermediate inputs from tables for other regions. This paper compares the performance of four of such 'cross-regional' methods. Two of these were already proposed in the literature, whereas the other two are based on recent advances in regression analysis. The methods are tested not only against each other, but also against traditional methods that do not employ cross-regional information. To this end, twenty-seven regional input-output tables for China in 1997 and 2002 are used.
