This paper examines the value of political participation by private entrepreneurs in China. Using a unique sample of all initial public offerings by entrepreneurial firms during 1994-2007 and political participation by the controlling entrepreneurs, we test the hypothesis that firms with entrepreneurs who participate in politics are able to exploit rent-seeking opportunities that normal firms do not have access to. We document that the long-run stock performance after the IPO of firms controlled by entrepreneurs who participate in politics is superior to that of common entrepreneurial firms. Our results also show that political participation has a significant positive effect on change in operating performance and a negative effect on first-day returns. Moreover, we find that economic development and local institutions are important for this value effect. The difference in performance is even larger in regions characterized by more abundant rent-seeking opportunities, indicating that the value effect of political participation likely originates from rent seeking. This finding is consistent with the hypothesis that political participation facilitates entrepreneurs’ rent seeking.
