This article investigates the use of a series of composite indicators as a measure of global competitiveness. Using Spearman and Kendall (1938) rank correlation tests, we show that rankings resulting from those competitiveness indices are highly correlated. Furthermore, a critical analysis of these indicators indicates that they cannot be used as an empirical measure of countries competitiveness. Indeed, the lack of theoretical and empirical basis for the choice of variables and weights inside the indices brings some interpretations problems in terms of economic policy. "Scores" obtained using these indicators have to be taken with caution. These indices have to be rather used as indicatory variables or competitiveness benchmarks resulting in dashboard.
