摘要：The main aim of this paper is to analyze the changes in productivity and the main intersectoral influences associated with the telecommunications services in the main world economies, such as Germany, Brazil, China, the United States, France, Japan and the United Kingdom. To accommodate this task, we applied two techniques on interregional inputproduct matrices between 2004 and 2014: (i) total factor productivity and (ii) field techniques of influence. The main findings indicate that productivity and efficiency gains in the telecommunications sector can lead to less intersectoral influence on the type of service itself.
