資安專利數的影響因素分析：以美國都會區為例

近年來資訊安全產品的需求與重要性逐漸增加。本論文以美國383個都會區為研究樣本，探討各都會區的資安技術創新表現差異及其決定因素。我們以各都會區2015-2017年內申請且核准的資訊安全專利存量為被解釋變數，各都會區的研發能量、人口密度和產業強度等為解釋變數，分別採用OLS與負二項計量方法進行實證分析。本文實證結果發現，資訊安全專利數多寡除受各都會區電腦科學教授人數與研發金費多寡影響外，資訊產業、金融產業與政府部門的產業強度也呈現顯著正相關。

The demand of cybersecurity products have increased dramatically in recent years. In this paper, 383 metropolitan areas in the United States are taken as research samples to explore the differences of cybersecurity technology innovation performance and its determinants. The approved cybersecurity patent stock in each metropolitan area from 2015 to 2017 were our dependent variable. Their research and development expenses and industrial strength were the explanatory variable. The empirical study was conducted by OLS and the Negative Binomial Model separately. The empirical results show that the number of cybersecurity patents is not only affected by the number of computer science professors and the amount of research and development expenses in each metropolitan area significantly, but also by the intensity of the information industry, financial industry and governments with positive relationship.
