The weak growth of global economy and trade, combined with the vicious cycle of global high debt and low growth, has led many commercial banks to start tightening their loans, which makes the financial constraints faced by enterprises more and more obvious. In order to help enterprises cope with financial problems, many practitioners and scholars have shifted their focus on the power of supply chain itself recently. Based on the theory of supply chain dynamic capabilities while following the theoretical logic of “dynamic capabilities-cooperation strategy-capital flexibility”, this paper explored the specific mechanism of supply chain capabilities to affect enterprise capital flexibility. This paper validated its hypotheses by Structural Equation Model with 249 enterprise samples. The results indicated that in order to improve capital flexibility of supply chain members through supply chain arrangements, firstly, supply chain members need work together to build supply chain dynamic capabilities (knowledge accessing capability, coordination capability, reconstruction capability).
