Abstract

With the gradual approach of the era of negative interest rates and the large-scale outbreak of the epidemic, the fragility of the global financial market has suddenly increased, and the stock market with strong interest rate and capital sensitivity has been greatly affected. my country’s stock market is characterized by its high resilience and resistance. Risk capability has become an important channel for capital flows, and the instability of the stock market has also increased, and its vulnerability has seriously affected financial security and the stable, healthy and sustainable development of the economy. However, most of the existing research stops at discovering the overall vulnerability of our country’s stock market and putting forward countermeasures. Few scholars have conducted identification and prevention research on the vulnerability of a certain sector of the stock market, resulting in a lack of generalizable vulnerabilities in specific sectors. Based on the 2010-2020 GEM data, this paper uses factor analysis and the fuzzy comprehensive evaluation of angle cosine weighting to examine the vulnerability of the GEM and construct a quantifiable GEM vulnerability index—the GEM Comprehensive Risk Index. While innovating the vulnerability evaluation index system of a single sector, it has also enriched the vulnerability research system of the financial market, providing reference for the research of other sectors, especially the science and technology innovation board, which shoulders important missions and great expectations. Furthoremore, it is undoubtedly a scientific and reasonable reference for supervisory authorities.
