Evaluation of Foreign Exchange Rate Exposure for Publicly Listed Firms of Chinese A Shares
Abstract
This study's objective was to evaluation the issue of exchange rate exposure about publicly listed firms of Chinese A Shares. A new model of Measure and Calculate with lagged exchange rate variable is proposed. The new model can estimate the dynamic relation between exchange rate movements and firm value, hence overcome the deficiency of Jorion's model. The compare of the two models' empirical results indicates that the new model is more useful and effective in estimating the foreign exchange rate exposure. The following conclusions:⑴ 43.59% of the sample firms are highly exposed to lagged foreign exchange risks and 85.29% of them benefit from the depreciation of RMB; ⑵ not to find the significant relation between firm size and exposure; ⑶ to consider the more degree of foreign exchange rate exposure for manufacturing firms. Key words: foreign exchange rate; risk exposure; risk evaluation model; Chinese A Shares; public listed firmsRésumé: L'objectif de cet article est d'évaluer les problèmes du risque de change des sociétés chinoises cotées aux actions A. Un nouveau modèle de mesure et de calcul avec une variable retardée de l'exposition au risque de change est proposé. Ce modèle peut évaluer les effets dynamiques des fluctuations de taux de change sur les rendements boursiers et compenser les insuffisances du modèle de Jorion qui n'arrive pas à détecter les défauts de l'exposition au risque de change des sociétés cotées en Chine. En comparant le nouveau modèle avec le modèle de Jorion, nous constatons que le nouveau modèle peut expliquer mieux le problème de l'exposition au risque de change des sociétés cotées en Chine: ⑴ 43,59% des entreprises sélectionnées sont exposées aux risquex de change retardés de premier ordre et 85,29% d'entre elles bénéficient d'une dépréciatin de RM; ⑵ Il n'y a pas de corrélations significatives entre la taille de l'entreprise et l'exposition au risque de change; ⑶Les sociétés chinoises de manifacturation assument une exposition importante exposition au risque de change.Mots-clés: devise étrangère; exposition au risqué; modèle d'évaluation des risqué; actions A, sociétés cotées
