文摘Under the assumptions that investment return increases with the increase of the cash-flow rights held by the controlling stockholder, and the increase of investment return decreases the marginal profit-diverting cost. This paper designs a model to show that: below a threshold level, with the increase of the cash-flow rights held by the controlling stockholder, the profit-diverting shares will probably go up, and the Tobin's Q of a listed company maybe go down; Only after that threshold point, does the profit-diverting share become a decreasing function of the cash-flow rights held by the controlling stockholder, and hence does Tobin's Q become an increasing function of the cash-flow rights held by the controlling stockholder.
