Business efficiency.

In the era of the digital economy, building an internationally competitive manufacturing industry with intelligent manufacturing as its main focus is the only way to promote the transformation of a country into a manufacturing power and achieve high-quality economic development. To explore whether Digital transformation can improve the core competitiveness of traditional manufacturing enterprises, and what factors affect this process, this study establishes the core competitiveness system of enterprises through the principal component analysis(PCA) method and discusses the above issues through the construction of a double difference model. The results of this research from China’s traditional manufacturing industry are as follows. (i) The digital transformation of enterprises has significantly improved their core competitiveness and has a certain time lag effect. (ii) In the process of enterprise digital transformation, enterprise management capabilities, environmental uncertainty, and enterprise operational efficiency will positively enhance the results of enterprise digital transformation. (iii) The enhancement of core competitiveness caused by digital transformation is more significant for the market leaders and laggards. (iv) Compared with non-state-owned enterprises, the Digital Transformationn of state-owned enterprises has a more obvious effect on promoting their core competitiveness. (v) In comparison with enterprises with low government subsidies, the Digital Transformation of enterprises with high government subsidies plays a more significant role in promoting their core competitiveness. In addition, this study proposes policy guidance and practical guidance for digital transformation to accelerate the promotion of core competitiveness of traditional manufacturing industry.数字经济时代，以智能制造为核心打造具有国际竞争力的制造业，是推动一国向制造强国转型、实现经济高质量发展的必由之路。为探究数字化转型（Digital Transformation）能否提升传统制造企业核心竞争力，以及哪些因素会对这一进程产生影响，本研究通过主成分分析（PCA）方法构建企业核心竞争力评价体系，并借助双重差分模型对上述问题展开探讨。基于中国传统制造业的本研究结果如下：(i) 企业数字化转型可显著提升其核心竞争力，且存在一定时滞效应；(ii) 在企业数字化转型进程中，企业管理能力、环境不确定性与企业运营效率可正向强化数字化转型的赋能效果；(iii) 数字化转型对核心竞争力的提升效应，在市场领先者与市场落后者群体中更为显著；(iv) 相较于非国有企业，国有企业的数字化转型对其核心竞争力的提升作用更为显著；(v) 相较于获得低额政府补贴的企业，获得高额政府补贴的企业开展数字化转型对核心竞争力的助推作用更为显著。此外，本研究针对数字化转型提出政策指引与实践路径，以期加快传统制造业核心竞争力的提升进程。
