Is the Stock Market Just a Side Show? Evidence from a Structural Reform
The 2005 split-share reform in China mandated the conversion of previously non-tradable shares into
tradable status. The reform was swift and changed investors?ability to trade corporate equities in
a US$400 billion market. This paper examines the e¤ects of the 2005 stock market reform on ?rms?
real and ?nancial outcomes. It does so exploiting multiple institutional features of the conversion
program. We ?rst examine a small pilot trial conducted at the beginning of the reform, which we are
able to replicate using the same data and selection criteria that was used by regulators. We also take
advantage of the staggered nature of the larger conversion schedule, whereby over a thousand ?rms
converted their outstanding shares at di¤erent times within a pre-speci?ed window. These various
wrinkles produce counterfactuals against which to gauge the economic e¤ects of secondary equity
trading. Using a time-varying treatment estimation approach, we identify increases in corporate
pro?tability, investment, value, and productivity as pre-existing shares were allowed to trade in or-
ganized exchanges. We also identify changes in ?rms?propensity to issue new shares, pay dividends,
and engage in merger deals. Our ?ndings provide new insights on the role of stock markets in shaping
corporate behavior and on the impact of regulation on economic growth.
