Through an in-depth analysis of key financial policy tools such as interest rates and money supply, it reveals how these policies trigger different responses in the stock market during periods of economic expansion and contraction, such as changing factors such as the cost of capital, corporate earnings expectations, market liquidity, and investors’ risk appetite. In addition, from the perspective of global financial market integration, this paper studies the linkage effect of international financial policy changes such as the Federal Reserve’s decision-making on China’s stock market, and analyzes its transmission path. It is pointed out that in the complex international environment, the uniqueness and independence of domestic financial policies are important, and timely adjustment of financial policies, improvement of risk prevention mechanisms and strengthening market supervision are of great significance to maintaining the stability of the stock market and guiding its healthy development.
