Cross-Hauling and Regional Input-Output Tables: The Case of the Province of Hubei, China

Data for the Chinese province of Hubei are used to assess the performance of Kronenberg’s CHARM, a method that takes explicit account of cross-hauling when constructing regional input-output tables. A key determinant of cross-hauling is held to be the heterogeneity of the products of individual sectors, which is estimated using national data. However, contrary to the authors’ earlier findings for Finland, CHARM does not generate reliable estimates of Hubei’s sectoral exports, imports and volume of trade. It is crucial, therefore, especially in relatively small regions, to make adequate allowance for any known divergence between regional and national technology and heterogeneity.
