生产性服务业集聚与全球价值链地位攀升

结合中国工业企业数据和城市经济数据，运用工具变量回归从专业化和多样化层面探讨中国生产性服务业集聚对制造业全球价值链地位的影响。研究发现，从整体上看，不论是专业化还是多样化，生产性服务业集聚均能够显著提升中国制造业的全球价值链地位。分样本检验显示，生产性服务业集聚对全球价值链地位的提升作用主要存在于沿海省份、资本和技术密集型行业以及中小企业。在作用机制方面，生产性服务业专业化集聚主要通过提高创新水平和推动全要素生产率促进全球价值链地位的提升，而多样化集聚则通过加快要素流动和推动全要素生产率来提升全球价值链地位。

Producer Services Agglomeration and the Global Value Chain Status

This paper discusses the dynamic influence of producer services agglomeration on the global value chain status of manufacturing enterprises in China. The results show that producer services agglomeration has a significant positive effect on the global value chain status of manufacturing enterprises, both at the perspective of specialization and diversification. Sub sample test shows that the positive relationship between producer services agglomeration and the global value chain status mainly exists in coastal provinces, capital and technology intensive enterprises, and small and medium sized enterprises. In terms of paths, the specialization agglomeration of producer services promotes the global value chain status of manufacturing industry by improving the level of innovation and promoting total factor productivity, and diversified agglomeration promotes the global value chain status of manufacturing industry by accelerating factor flow and promoting total factor productivity
