【摘要】 本文从量变和质变双重视角探讨产业链“链主”培育对本地企业核心技术突破的赋能机制与效应。研究结果表明：产业链“链主”培育能够显著促进本地企业核心技术突破，主要表现为核心技术申请量增加以及技术邻近度降低，这一作用有赖于产业生态改善和供应链协同溢出两条机制；异质性检验结果表明，产业链“链主”培育对核心技术突破的赋能效果在数智应用程度更高、内销市场导向、经营环境较差的企业分组中更为明显。进一步研究发现，“链主”国有属性和本地企业议价能力较强时，“链主”培育对本地企业核心技术突破的促进作用更为显著。更多还原

【Abstract】 This paper explores the enabling mechanisms and effects of industrial chain “anchor firm” cultivation on breakthroughs in core technologies of local enterprises from the dual perspectives of quantitative and qualitative changes. The research results indicate that the cultivation of industrial chain “anchor firms” significantly promotes breakthroughs in core technologies of local enterprises, mainly manifested as an increase in core technology patent applications and a decrease in technological proximity. This effect relies on two mechanisms: industrial ecology improvement and supply chain coordination spillover. Heterogeneity tests show that the enabling effect of industrial chain “anchor firm” cultivation on core technology breakthroughs is more pronounced in enterprises with a higher degree of digital-intelligent application, a domestic market orientation, and poorer operating environments. Further analysis reveals that the promoting effect of “anchor firm” cultivation on breakthroughs in core technologies of local enterprises is more significant when the “anchor firm” has state-owned attributes or local enterprises possess stronger bargaining power.更多还原
