The impact of corporate social responsibility is very broad, especially on stock prices. This paper takes the 2010-2019 listing cabinet company as a sample to explore the correlation between corporate social responsibility and stock price synchronicity. Experimental results show that corporate social responsibility can reduce the degree of corporate stock price by market factors, and furthermore, with corporate profitability as the threshold variable, it can be learned that compared with the more profitable companies, less profitable companies are more willing to invest in corporate social responsibility, to ensure that the company's stock price is not susceptible to market stock price fluctuations. Finally, under the group holding pattern, it can be learned that the corporate social responsibility of only non-single-family group enterprises is vulnerable to market factors.
