Working Paper 11-18 - Value chain integration of export-oriented and domestic market manufacturing firms - An analysis based on a heterogeneous input-output table for Belgium

For a finer analysis of competitiveness and value chain integration, this working paper presents a micro-data based breakdown of manufacturing industries in the 2010 Belgian supply-and-use and input-output tables into export-oriented and domestic market firms. The former are defined as those firms that export at least 25% of their turnover. Analyses based on the resulting export-heterogeneous IOT reveal differences between the two in terms of input structures and import behaviour: export-oriented manufacturers have lower value-added in output shares, and they import proportionally more of the intermediates they use. Moreover, exports of export-oriented manufacturers generate a substantial amount of value added in other Belgian firms, in particular providers of services. The policy implication of these results is that Belgium's external competitiveness depends not only on exporters but also on firms that mainly serve the domestic market. To maximise the impact of export promotion in terms of domestically generated value added, the entire value chain for the production of exports must be taken into account.
