摘要：经济高质量发展对企业创新能力提出了更高要求，企业需要将内部能力与外部环境有效结合以提高创新效率。基于知识基础和复杂网络理论，本文构建知识网络效率、要素市场化与新产品开发的理论模型，并利用我国汽车制造企业的面板数据，通过双向固定效应负二项回归模型对研究假设进行实证检验，研究结果表明：知识网络全局效率与企业新产品开发绩效呈正向关系，知识网络局部效率与企业新产品开发绩效呈负向关系；高水平资本市场化程度削减全局效率对企业新产品开发绩效的促进作用，高水平劳动力市场化程度增强全局效率对企业新产品开发绩效的促进作用，高水平技术市场化程度增强局部效率对企业新产品开发绩效的抑制作用。因此，本文提出相应的政策建议：全面推进要素市场化配置改革的纵深发展以强化企业创新主体地位；技术融合是实现发明创造的主要途径，企业应根据自身情况选择不同的知识组合策略，同时注重组合策略与各类要素市场化发展的匹配程度以提升新产品开发绩效。

Abstract: High-quality economic development puts forward higher requirements for firms' innovation capabilities. Firms need to combine internal capabilities with external environment to improve innovation efficiency. Based on the theories of knowledge baseand complex network, this paper constructs the model of knowledge network efficiency, factor marketization and new product development (NPD). Using panel data of China's automobile manufacturers, proposed hypotheses are empirically tested by two-way fixed effect negative binomial regression model. The results showthat global efficiency of knowledge network is positively correlated with NPD performance, and local efficiencyof knowledge network is negatively correlated with NPD performance. Higher capital marketization reduces thepromotion of global efficiency on NPD performance, higher labor marketization enhances the promotion  f global efficiency on NPD performance, and higher technology marketization strengthens the inhibition oflocal efficiency on NPD performance. It is suggested that the in-depth reform of factor marketization is needed to strengthen the firms' dominant position in the innovation system. Technology convergence is vital forinventing,and firms should choose different strategies of knowledge combination. Meanwhile,firms should also take factor marketization into consideration in order to improve NPD performance.
