OUTSOURCING AND FRAGMENTATION IN SINGAPORE'S MANUFACTURING INDUSTRY

This paper studies the impact of outsourcing on productive performance of manufacturing industries in Singapore. The paper develops an outsourcing measure based on the narrow definition of intermediate imports given by Feenstra and Hanson (1996, 1999). Based on the input-output tables, the study uses 5-digit industrial-level classifications to measure the impact of outsourcing on productivity of the manufacturing industries in Singapore from 1995–2004. The outsourcing measure is further decomposed by import of services, import of IT services and import of business services. This decomposition allows us to study the impact of outsourcing of services in addition to the cross-border fragmentation of products and components. The results suggest strong positive impact of cross-border sourcing on the productivity of the manufacturing sector. The decomposition of outsourcing measure indicates that the manufacturing industries are more involved in cross-border sourcing of services, particularly in business services.
