    International audience; Avant de se propager à l’échelle mondiale, l’épidémie de coronavirus est apparue dans la province du Hubei. Pour contenir la propagation du virus, le gouvernement chinois a imposé des mesures de quarantaine, entraînant un ralentissement de l’activité économique. Nous étudions ici la manière dont ce ralentissement de la production, initialement limité à la province de Hubei, se diffuse à l’économie mondiale via les chaînes de valeur internationales. La dépendance à l’égard des intrants chinois a augmenté de manière spectaculaire depuis le début des années 2000. De ce fait, la plupart des pays sont exposés au ralentissement de l’activité en Chine, à la fois directement via leurs importations de produits intermédiaires chinois et indirectement, du fait de la valeur ajoutée chinoise incorporée à d’autres intrants à la production. Cette note quantifie l’exposition totale de la France comparée à celle d’autres pays. Dans un premier temps, nous calculons la part de la valeur ajoutée chinoise dans la production française. Ensuite, nous utilisons des données au niveau des pays et des secteurs pour quantifier l’impact des mesures de quarantaine sur le PIB français.

    The Second ENCORE European conference in October 2021 in Paris, France, has gathered two communities, the Risk Perception and Behaviour Survey of Surveyors (Risk-SoS) and the H2020-DRS01 Cluster on risk perception and adaptive behaviour (a grouping of several Horizon Europe – Disaster Resilient Societies projects, most notably RESILOC, BUILDERS, ENGAGE, LINKS, CORE and Risk PACC). During the Covid-19 pandemic lockdowns in 2020 and 2021 the monthly Risk-SoS webinars have been keeping the risk perception and adaptive behaviour research community together with panels on the role of theories in research on hazards adaptation, resilience and vulnerability. Topics were on risk perception and behaviour across challenges and time, across disciplines and methods, as well as panel and longitudinal approaches, and workshops on theories and methods to advance the design of a collective surveying approach with potentially common questions and answers’ scales to foster comparability. The Risk-SoS webinars have also been discussing the results of the Survey of Surveyors and sustaining the collective effort to build a harmonised approach for risk perception and adaptive behaviour assessment. In an hybrid format, the Second ENCORE conference has gathered 25 researchers and experts from 10 countries (Austria, Belgium, France, Germany, the Netherlands, Poland, Spain, Sweden, Switzerland and the United Kingdom) at the Ministry of Research in Paris, France.

    International audience; Before spreading globally, the Covid-19 epidemic was concentrated in the Hubei province. To contain the spread of the virus, the Chinese government has imposed quarantine measures and travel restrictions, entailing the slowdown of economic activity. We study the propagation of this geographically concentrated productivity slowdown to the global economy, through global value chains. Reliance on Chinese inputs has dramatically increased since the early 2000s. As a consequence, most countries are exposed to the Chinese productivity slowdown, both directly through their imports of Chinese inputs and indirectly, through other inputs themselves produced with some Chinese value added. This note aims at quantifying the total exposure of France compared to other countries. First, we compute the share of Chinese value added in French production. Then, we use data at the country and sector levels to quantify the impact of travel restrictions on French GDP.
