This paper uses the change in individual securities accounts as a measure of equity funding supply to examine whether the persistent timing effect on capital structure exists for the Chinese equity market. This new equity timing measure avoids previous criticisms over a timing measure not being independent of a firm's characteristics of capital structure. Our empirical results show that this new measure is an effective market timing variable for issuing equity in the Chinese equity market, and that a persistent effect of equity market timing on firm capital structure exists for more than 7 years. This paper offers evidence that the market conditions of equity funding supply play an important role in corporate financing decisions in China.
