摘　　要：运用工业企业数据和海关统计数据,考察研发投入对中国制造业贸易网络中心度影响。实证研究表明,研发投入增加对企业贸易网络中心度提升产生显著正向影响,机制分析表明,研发投入可以通过优化要素投入结构、促进企业创新和提升国内增加值率来推动贸易网络中心度攀升,而企业吸收能力、融资约束程度和市场竞争程度对研发投入提升中心度起调节作用;异质性分析发现,在出口高技术产品、有外资参与、没有政府补贴的企业中,研发投入对企业贸易网络中心度促进作用更大。通过推进高水平对外开放、扩大贸易伙伴范围、优化外贸产品结构、强化企业创新主体地位等措施可以增进我国国际分工地位。This study utilizes industrial enterprise data and customs statistical data to explore the impact of R&D investment on the centrality of China's manufacturing trade network.The analysis of the impact mechanism reveals that R&D investment enhances trade network centrality by optimizing factor input structures,fostering enterprise innovation,and increasing the domestic value-added rate.Empirical results indicate that increased R&D investment significantly and positively impacts the centrality of enterprise trade networks.Additionally,enterprise absorptive capacity,financing constraints,and market competition play moderating roles in this relationship.Heterogeneity analysis shows that R&D investment has a greater impact on trade network centrality in enterprises exporting high-tech products,involving foreign capital,or lacking government subsidies.Measures such as advancing high-level openness,broadening the scope of trade partnerships,optimizing the structure of foreign trade products,and strengthening enterprises as innovation entities can enhance China's position in the international division of labor.
