Recent changes in intersectoral relationships: a study of service and industrial activities

Abstract

This study examines the changes in recent decades in the links between the different activities of the economy, especially in those links between manufacturing and services. This research seeks to analyze the linking (directions) and the intensities (value) of the intersectorial linkages in Brazilian economy from 1995 and 2010. The research is structured into two basic points: 1) A review of the theoretical approaches concerning the evolution and the linkage between industrial activities and services in economic, and 2) developing indicators using a combination between the network analysis methodology (Pajek software) and input-output matrix data (WIOD, 2014). Furthermore, we demonstrated that in most countries, the relationship between manufacturing and services are the main components of the network density, quantifying the importance of this relationship in the productive structure.
