The Impact of Volkswagen Dieselgate on the Taiwanese Automotive Market

福斯柴油門事件對臺灣汽車市場之影響

本文研究2015年福斯柴油廢氣造假醜聞對臺灣汽車市場之影響。利用差異中差異實證策略與新車登記資料，我們發現在自用小客車市場，福斯汽車之季銷售下降超過20%，但一年後銷量很快就回復。在營業用小客車市場，並未對該醜聞產生反應。在群體聲譽方面，我們並未發現對其他德國汽車品牌之外溢效果，顯示在臺灣對污染之擔憂並未延伸至其他同國家之品牌。

This study examines the effects of the 2015 Volkswagen diesel emissions scandal on the Taiwanese new-car market. Using a difference-in-differences empirical strategy and administrative data on new-car registrations, we determined that Volkswagen’s quarterly sales fell by more than 20% in the self-use market. However, Volkswagen’s sales recovered after one year. Business buyers in the B2B market did not respond to emissions scandal. Regarding collective reputation, we found no evidence of spillover to other German brands, indi-cating that environmental concerns in Taiwan did not extend to other brands within the same country.
