Based on the trade off theory, the paper analyzes the impact of the level of risk taking on the rate of corporate working capital target structure call back. The results of empirical research show that the increase of enterprise’s risk taking level will accelerate the call back rate of corporate working capital target structure, and the increase of real money supply level can significantly slow down the call back rate of corporate working capital target structure. At the same time, the improvement of the level of real money supply can reduce the risk exposure brought by the level of corporate risk taking, so as to reduce the impact of corporate risk taking on the call back rate of target structure of working capital. The paper further examines the effects under different risk preferences, that is, corporate risk taking and real money supply under different risk taking on the target structure of working capital. The test results show that the level of risk taking is positively correlated with the call back rate of target structure of working capital for enterprises with risk preference tendency. With increasing of the level of enterprise risk taking, the deviation degree of working capital target structure will be further increased by corporations with risk aversion tendency. In addition, corporations with a risk appetite, the increase of the actual money supply level will magnify the deviation degree of the target structure of corporation working capital, and have a greater impact on low risk taking enterprises. In risk averse corporations, the rate of target adjustment of working capital structure does not show a significant sensitivity to the actual money supply level, and shows a similar effect in high or low risk taking corporations.
