La diversification économique des villes canadiennes non-métropolitaines entre 1971 et 2016
Bibliographic record
Abstract
La diversification économique fait l’objet d’un intérêt renouvelé depuis la Grande Récession de 2008. Supposée de renforcer la résilience des économies régionales face aux crises, la diversification est poursuivie comme objectif politique par de nombreux acteurs. Les régions non-métropolitaines, qui font face aux défis séculaires liés à la dépendance mono-industrielle, y voient une urgence particulière. Si des travaux précédents ont démontré que la diversification a bien eu lieu dans ces régions—en fait de manière accélérée relativement aux centres métropolitains—ce phénomène reste peu exploré. Afin d’éclairer ces enjeux, deux études sont proposées. Premièrement, une analyse est effectuée de la composition sectorielle de la diversification déjà observée dans les régions urbaines non-métropolitaines canadiennes, à travers une longue période de 1971 à 2016. Cette analyse a permis de constater qu’une bonne partie de la « diversification » observée dans ces régions est un artéfact statistique du déclin des industries antérieurement dominantes, comme celles du papier et de l’aluminium. Deuxièmement, des modèles de régression sont construits afin d’étudier la contribution de différentes variables régionales—la composition industrielle initiale, la diversité reliée et non-reliée, et l’accès à d’autres marchés—au développement de nouvelles industries et spécialisations menant à la diversification. Les résultats de cette analyse ont réaffirmé le rôle de l’accès aux marchés pour le développement régional, mais aussi de la composition industrielle initiale locale, ce qui réitère l’importance de prendre en compte celle-ci dans l’élaboration des politiques de développement régional qui correspondent aux conditions locales. <br /><br /> Economic diversification has experienced renewed interest since the Great Recession of 2008. Believed to strengthen the resilience of regional economies when faced with crises, various actors have pursued diversification as a policy goal. Non-metropolitan regions, confronted with challenges of secular decline resulting from dependence on a single industry, are particularly concerned. While previous works have shown that diversification has indeed occurred in these regions—in fact, more quickly than in metropolitan centres—the phenomenon remains little studied. In order to clarify these issues, two studies are proposed. Firstly, an analysis is conducted of the sectoral composition of the diversification already observed in Canadian non-metropolitan regions, throughout the period from 1971 to 2016. This analysis demonstrated that much of the “diversification” previously observed in these regions is a statistical artefact of the decline of previously dominant industries, such as paper and aluminum manufacturing. Secondly, regression models were constructed to study the contribution of different regional variables—initial industrial composition, related and unrelated diversity, access to the North American market—to the development of new industries and specializations which contribute to diversification. The results of this analysis reaffirmed the importance of market access for regional development, but also of local initial industrial composition. This serves to reiterate the importance of the latter when creating regional development policies appropriate to local conditions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
