    摘要: 自1970年代石油危機以來，各國傳統內燃引擎車(ICEV)的銷售佔比逐漸下 降，而油電混合動力車(HEV)和電池電動車(BEV)的比例顯著提升。本文利 用專利新穎性指標衡量汽車產業的技術創新，並通過專利數據了解各類型汽車的 專利分佈。基於 Verhoeven 和 Bakker 等人(2016)計算專利新穎性的方法，我 們使用來自八個專利局的資料，並新增兩個時間窗口(10年及20年)來建構專利 新穎性指標。我們分析了各國傳統車廠及中美電動車廠在1990年至2023年間於美 國專利局的專利申請，發現Tesla在專利新穎性方面顯著領先於其他美國電動車 廠、中國電動車廠及傳統車廠;而比亞迪雖不及Tesla，但在專利創新程度上領先 於其他美國及中國電動車廠，並且超越了中國的傳統車廠。
    Since the 1970s oil crisis, the sales share of traditional internal combustion engine vehicles has gradually declined, while the proportion of hybrid and electric vehicles has significantly increased. This study utilizes patent novelty indicators to measure technological innovation in the automotive industry and examines the distribution of patents across different types of vehicles through patent data. Based on the method for calculating patent novelty by Verhoeven and Bakker et al. (2016), we use data from eight patent offices and introduce two additional time windows (10 years and 20 years) to construct the patent novelty indicators. We analyzed the patent applications of traditional automakers and electric vehicle manufacturers from China and the U.S. at the United States Patent and Trademark Office (USPTO) from 1990 to 2023. The findings reveal that Tesla significantly leads other U.S. electric vehicle manufacturers, Chinese electric vehicle manufacturers, and traditional automakers in terms of patent novelty. Although BYD lags behind Tesla, it surpasses other U.S. and Chinese electric vehicle manufacturers and outperforms traditional Chinese automakers in terms of patent innovation.
