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. Jiang X., Dietzenbacher E. et Los B. Une meilleure estimation des tableaux d'échanges inter-industriels régionaux à partir des méthodes interrégionales, Regional Studies . Beaucoup des tableaux d'échanges inter-industriels régionaux sont estimés à partir des méthodes hors enquêtes. Souvent, les renseignements à la marge du tableau prévu sont complétés par des renseignements détaillés sur des facteurs de production intermédiaires qui proviennent des tableaux relatifs à d'autres régions. Cet article cherche à comparer la performance de quatre méthodes ‘interrégionales’ de ce type. Deux méthodes ont déjà été proposées dans la documentation, alors que les deux autres sont basées sur des développements récents dans le domaine de l'analyse de régressison. On teste ces méthodes non seulement l'une par rapport à l'autre, mais aussi par rapport aux méthodes traditionnelles qui n'emploient pas de renseignements interrégionales. A cette fin, on emploie vingt-sept tableaux d'échanges inter-industriels régionaux pour la Chine de 1997 à 2002.

Verbesserte Schätzung von regionalen Input-Output-Tabellen mit Hilfe überregionaler Methoden, Regional Studies . Viele regionale Input-Output-Tabellen werden mit Hilfe von anderen Methoden als Erhebungen geschätzt. Oft werden die Informationen über die Spannen in der prognostizierten Tabelle durch vollständige Informationen über die intermediären Inputs von den Tabellen für andere Regionen ergänzt. In diesem Beitrag wird die Leistungsfähigkeit von vier solchen ‘überregionalen Methoden’ miteinander verglichen. Zwei dieser Methoden wurden bereits in der Literatur vorgeschlagen, während die anderen beiden auf aktuellen Fortschritten bei der Regressionsanalyse beruhen. Die Methoden werden nicht nur im Vergleich zueinander überprüft, sondern auch im Vergleich zu herkömmlichen Methoden, bei denen keine überregionalen Informationen genutzt werden. Zu diesem Zweck kommen 27 regionale Input-Output-Tabellen für China in den Jahren 1997 und 2002 zum Einsatz.

Estimación mejorada de tablas de insumo-producto regional con ayuda de métodos transregionales, Regional Studies . Muchas tablas de insumo-producto regional se calculan mediante métodos indirectos. Con frecuencia, la información sobre los márgenes de la tabla proyectada se complementa con información exhaustiva sobre los insumos intermedios de las tablas para otras regiones. En este artículo comparamos el desempeño de cuatro de estos métodos ‘transregionales’. Dos de estos métodos ya se han propuesto en la bibliografía mientras que los otros dos se basan en avances recientes del análisis de regresión. Los métodos se comprueban no solamente para compararlos entre sí sino también para compararlos con métodos tradicionales que no emplean información transregional. Para este propósito se utilizan veintisiete tablas de insumo-producto regional para China en 1997 y 2002. Métodos indirectos Métodos transregionales Tablas de insumo-producto regional China
