This study uses panel data analysis to examine the relationship between political connections and firm performance in Chinese firms from 2004 to 2008. We define firm‐level political connections and demonstrate a robust result for the positive relationship between political connections and firm performance. In addition, we integrate the effects of ownership structure, related‐party transactions and political connections into our analysis and continue to show a positive relationship. We show that political connections dampen the negative effect on firm value of related‐party transactions. Finally, we demonstrate channels through which the benefits of political connections are realized in terms of greater cash holdings, larger long‐term loans, lower financing costs, larger sales and lower sales costs. Our results indicate that state‐owned and non‐state‐owned enterprises use political connections equally effectively to enhance performance.
