This paper constructs quantitative measures of global competitiveness and linkages in order to assess their association for high-tech clusters in HSIP. We apply the Balassa’s revealed comparative advantage (RCA) concept to measure competitiveness. Ranking by RCA, there are half of top 20 traded goods belong to the semiconductor cluster. We investigate cross-cluster linkages using financial statements from annual company reports of HSIP firms. We find that semiconductor manufacturing strongly links backwardly to the semiconductor equipments and materials cluster and forwardly to the integrated circuit design cluster. Furthermore, These results reveal that a high ranking in global competitiveness for some high-tech clusters may positively associate with their strong cross-cluster linkages.
