%X This study aims at presenting a new computation index, which simultaneously measures the time and space variation of the various economic indices. The elaboration method of the space-time index is based on a matrix construct, the time and space variation of the analyzed economic index being represented via a system of vectors in plane. The practical application of the compound index is exemplified by employing the data on the growth rate of the GDP/inhabitant, calculated for two spatial entities: Romania and the European Union, for the period 1999-2008. The obtained findings confirm the fact that the proposed space-time index is a good analysis tool for the measurement of the time and space variation related to the various economic indices, as well as for testing the economic convergence for discrete time moments.
