以Cobb-Douglas生產函數分析新冠肺炎後台灣半導體產業研發投入與獲利能力之關聯性

Use Cobb-Douglas to Analyze the Pertinence of R&D Investment and Profitability of Semiconductor Industry after the COVID 19

摘要


本文以Cobb-Douglas生產函數來探討新冠肺炎發生後,台灣半導體產業研發投入與獲利能力之關聯性。2020年新冠肺炎席捲全球, 對於企業的影響是全面性的,國際研究暨顧問機構Gartner表示由於新冠肺炎衝擊半導體供應鏈及需求,2020年全球半導體營收年減少0.9%,成長大幅衰退,進而降低企業的投資意願,甚至影響研發投資, 而研發投資是企業技術創新的來源,也是半導體產業競爭力的泉源與持續發展的動力。本文以台灣證券交易所上市之13家半導體產業為研究對象,研究期間從2016年一月至2020年十二月,蒐集7800筆資料,透過相關資料的整理與統計分析,利用多元迴歸模型與Cobb-Douglas生產函數檢驗新冠肺炎發生後,研發投資強度、技術人員投資強度與專利權數對半導體產業獲利能力的影響,研究發現即使新冠肺炎發生,半導體產業揭露的研發投資對企業獲利能力仍有正面的影響,且研發投資對企業獲利能力也是正向影響並存在遞延效果。

This article used Cobb-Douglas Production Function to analysis the relationship between the Pertinence of R&D investment and profitability of semiconductor industry in Taiwan after the COVID 19. The COVID19 in 2020 had a comprehensive impact on companies, thereby reducing the willingness of companies to invest, and even affecting R&D investment. This article took the semiconductor industry listed on the Taiwan Stock Exchange as the research samples, and the research period was from 2016 January to 2020 December. Through the collection, sorting and statistical analysis of relevant data, and the use of multiple regression models and Cobb-Douglas production to examine the impact of R&D investment intensity, technical personnel investment intensity, and patent rights on the profitability of the semiconductor industry after the COOVID 19.It was found that even if the COVID19 occurred, that R&D investment disclosed by enterprises has a positive promotion effect on profitability of enterprises, and there is a lagging effect of R&D investment on the promotion of profitability of enterprises.
