A service sector classification scheme using economic data
Using economic data, this paper recreates a previously published service industry classification scheme that was derived using discursive data from interviews with industry experts. It triangulates the earlier results using a different methodology, and extends earlier classification schemes in a comprehensive, objective way. A principal component analysis of six sector parameter sets from a regression analysis of a productivity data set covering 14 countries produces three sector factors, the 'capital type', the 'innovation type' and the 'quality type', which form the basis of the classification scheme. A high degree of conformity is found between this and the previously published discursive-based scheme.
