In the Chinese stock market, the price of exchangeable stock is determined by the discounted future uncertain cash flow, while the price of non-circulating stock depends on per book value. In general, because investors holding non-circulating equity maintain the control power, corporate finance and investment decisions reflect their interests. The pricing mechanism of non-circulating stock violates the basic pricing principle of the capital market. Therefore, corporate finance decisions deviate from the NPV (net present value). As a result, excessive equity financing problems would occur in the listed companies.
