       论文摘要

    We employ China’s split share structure reform (SSSR) as a natural experiment to examine whether investors’ risk aversion affects firm diversification. Initially the controlling shareholders of Chinese listed firms were prohibited from selling off their holdings through public trading, and this restriction was later lifted through the SSSR. We predict that as the SSSR grants more opportunities to diversify through financial markets, the controlling shareholders have less need to rely on firm diversification to reduce risk. We also predict that this effect of the SSSR should be concentrated on private firms (non-SOEs), rather than state owned enterprises (SOEs), whose controlling shareholders have substantial personal wealth tied to the firms they control. Consistent with these predictions, we find that subsequent to the SSSR, non-SOEs restructure their businesses to reduce the scope and degree of diversification. And along with this change, these firms also display higher fundamental risk and increased industry-relatedness among their segments. We also find the increases in firm value (Tobin’s Q) that are associated with reduced diversification. In contrast, the effects of the SSSR are dampened or even non-existent for SOEs. Our evidence suggests that investors’ risk aversion is a significant force shaping a firm’s boundary.
