The involvement of major energy-exporting countries in geopolitical conflicts can easily lead to volatility in international energy markets and have an impact on the world economy. Based on a macroeconomic model and using counterfactual analysis and vector autoregression, the differential impacts of geopolitical conflicts on different economies through the volatility of the energy market was analyzed, and China's response measures based on the perspectives of energy security and national security was put forward. The results show that geopolitical conflicts have negative impacts on different economies through crude oil market volatility, with the European economy, which is more dependent on Russian energy, being affected to a greater extent. It is recommended to pay great attention to the risk of geopolitical conflicts, accelerate the formation of a diversified pattern of crude oil imports and energy consumption, stabilize investor expectations, improve the construction of the capital market and maintain the stability of the RMB exchange rate, so as to prevent the negative impacts that geopolitical conflicts may have on China's energy security.
