As at the end of 2020, about 1600 Chinese firms with a total market capitalization of $5.3
trillion are listed in stock exchanges outside Mainland China. This paper investigates the
motives and market valuation of overseas listed Chinese firms, and how they are affected by
the policy distortions in China’s capital market. Using an endogenous treatment effect model,
we find contrary to the valuation premium generally found in the literature for overseas listed
firms, Chinese firms listed in the US and Hong Kong stock market have a 50% valuation haircut
compared with their domestically listed counterfactual, and this effect persists even five years
after listing. Exploiting exogenous policy variations or shocks and firm heterogeneities, we
examine the effects of three policy distortions on this valuation haircut: restrictions on foreign
investment; administrative approval IPO system; and capital outflow controls. We find firms
affected by such policy distortions face greater valuation discounts.
