Analysis of the Main Factors Affecting National Vulnerability based on Principal Component Analysis
Download as PDF
To analyze the impact of climate change on national stability, this paper established a national vulnerability model that was analyzed by principal component analysis. It proposes seven climate vulnerability risk indicators, including competition for local resources, insecurities and migration of life, extreme weather events and disasters, fluctuating food prices and supplies, transboundary water management, sea level rise and coast The combined effects of degradation and climate policy. The improved principal component analysis is used as a basic model for assessing national vulnerability. A new variable SF is introduced as a composite score for a country vulnerability. Through the eigenvectors, the main factors affecting the vulnerability can be obtained.
