【摘要】 以2009～2019年305家上市制造企业为样本，通过建立固定效应回归模型，研究发现：随着吸收能力的增强、商业模式的改善和组织惯性的增大，制造企业开放式创新的“最优开放度”逐渐增加。进一步地，在内生性检验和稳健性检验，以及分行业回归模型中该研究结论也得到了支持。对于制造企业而言，随着其综合能力的提升，应动态调整自身开放度以提升创新绩效。更多还原

【Abstract】 Taking 305 listed manufacturing enterprises from 2009 to 2019 as samples, this study establishes a fixed effect regression model. The empirical analysis shows that with the enhancement of absorptive capacity, the improvement of business model and the increase of organizational inertia, the “optimal openness” of open innovation of manufacturing enterprises gradually increases. Further, the results of this study have passed the endogenous test and robustness test, and have been supported in the regression model of different industries. Therefore, for manufacturing enterprises, with the improvement of their comprehensive ability, they should adjust their openness dynamically to improve their innovation performance.更多还原
