Methods for regionalizing input-output tables

The present paper introduces the most common methods of regionalizing national input- output tables. First we describe the different groups of methods based on our review of the international literature regarding regionalization. Then we focus on particular methods that can be applied for Hungarian counties highlighting their advantages and disadvantages and synthetize the empirical results of them again based on the literature. On the basis of these experiences we attempt to create a complex method fitted to the available Hungarian regional data. For better understanding in th e end we apply our method on an illustrative example consisting of three regions with hypothetical sectors and data.
