Abstract:The changeable market environment will make the enterprise strategy in the process of dynamic adjustment. Based on this realistic background, combined with the strategy type and the strategic radicalism, this paper studies the impact of strategy dynamic adjustment on enterprise innovation performance. Firstly, we distinguish two strategic adjustment directions: conservative direction and offensive direction, and focus on enterprise innovation performance. Taking the A-share listed enterprises in Shanghai and Shenzhen during 2011-2019 as the research object, we measure the degree of strategic adjustment in different directions, and use the curve regression model with moderating effect to discuss the influence mechanism of financial flexibility on the shape and inflection point of the inverted U curve. The results show that in the process of adjustment towards the offensive direction, the positive influence interval of strategic adjustment on innovation performance will be prolonged. Therefore, enterprises should timely make relevant strategic adjustments along with the market environment, and pay attention not only to the possible economic consequences of the adjustment, but also to the direction and amplitude of the adjustment.
