The impact of China's protectionist policies on the capitalization of Chinese technology companies

In my research, I study the impact of China's protectionist policies on the market value of Chinese technology companies. The presented dataset covers the period from 2014 to 2024 and contains quotes from 14 Chinese technology companies and 3 market indexes: Shenzhen Component Index, Shanghai Stock Exchange and Hong Kong Stock Exchange. In this time period, I study the impact of 20 laws that could potentially have an impact on the capitalization of Chinese technology companies.
