    Modèle intersectoriel du Québec

    Economic and environmental impact for Québec for a selection of productive sectors

    The Québec input-output model is an analytical tool that measures the economic impact of spending projects on the Québec economy. The model assesses the impact of various types of expenditures, also called shocks, on labour, added value, imports, and other outputs.

    The results estimated by the input-output model make it possible not only to assess the economic impact of a sector, but also to compare this impact to that of other sectors of activity in the Québec economy.

    Several additional calculations can thus be performed using the economic impact results tables produced using the input-output model. The proportion of Québec content and the value-added and labour ratios are the most frequently used additional calculations. The Institut de la statistique du Québec has also expanded its impact studies to include greenhouse gas (GHG) emissions generated by economic activity.

    The comparison exercise is carried out using simulations of the average spending structures in the productive sectors of the economy at the aggregate level. The level of aggregation used is called level X.

    The economy is broken down into six major categories of productive sectors: the primary sector, utilities, construction, manufacturing, other services, and non-commercial sectors. The model performs simulations in increments of $100 million in operating expenditures for each of the six sectors based on the 2016 Supply and Use Tables and the 2020 adjustment parameters (average wages and fiscal and para-fiscal parameters).

    The bulletin presents the methodology used and the results for six aggregated sectors of the economy.
