In the context of the national strategic goal of innovation-driven high-quality development, binary innovation is an important strategic choice for enterprises to realize long-term development and maintain business performance. However, not all managers as strategic decision makers of enterprises have long-term strategic vision. Based on the high-order echelon theory and time-oriented theory, China's A-share listed companies was selected as the research object, the relationship between managerial myopia and corporate binary innovation was explored, and the moderating effects of managerial freedom and environmental uncertainty on it was empirically tested. It is found that managerial myopia significantly inhibits firms' binary innovation. Managerial freedom strengthens the inhibitory effect of managerial myopia on firms' binary innovation. And environmental uncertainty weakens the inhibitory effect of managerial myopia on firms' binary innovation. By expanding the correlation between managerial myopia and corporate binary innovation, this paper has some practical implications for the appointment of high-level managerial talents and the strategic choices of enterprises.
