产业链链主何以赋能本地企业全要素生产率?

How Can Industrial Chain Owners Empower the Total Factor Productivity of Local Enterprises?

在现代市场竞争已经由企业间竞争转变为产业链间竞争的背景下,发挥产业链链主的生态主导力是提升产业链现代化水平和保障产业链稳定的重要举措。利用2010—2020年中国时间序列投入产出表和A股制造业上市企业数据,通过产业链头部企业数量和投入产出关联系数界定产业链链主指标,探讨产业链链主对本地制造业企业全要素生产率的影响。研究发现,产业链链主能够显著提升本地企业全要素生产率,并且该提升作用在沿海地区、市场化水平高的地区、劳动密集型行业、技术密集型行业以及非国有企业中更为明显。机制检验发现,产业链链主可以通过集聚渠道、成本渠道和创新渠道提升本地企业全要素生产率。研究结论深化了对产业链链主动力优势的认识,验证了链主企业能够通过“以大带小”的方式带动本地企业发展,为政府制定相应的政策方针提供了有益的启示。

Competition in the modern market has changed from inter-enterprise competition to inter-industry chain competition,and the ecologically dominant force of the industrial chain owner can enhance the level of modernization of the industrial chain and guarantee its stability.Using a 2010—2020 time-series input-output table and data from listed manufacturing enterprises,this article defines the industry chain master indicator through the number of lead enterprises of the industry chain and the input-output correlation coefficient,and explores the impact of the industry chain master on the total factor productivity of local manufacturing enterprises.Industrial chain owners can significantly enhance the total factor productivity of local enterprises,and this enhancement is more obvious in coastal areas,areas with high marketization levels,labor-and technology-intensive industries,and non-state-owned enterprises.The mechanism test found that industrial chain owners can enhance the total factor productivity of local firms through the agglomeration,cost,and innovation channels.Our findings have deepened our understanding of the advantages of industrial chain initiatives and verified that chain master enterprises can drive the development of local enterprises by“bringing up the small with the big”,which provides useful insights for future governments to formulate corresponding policy guidelines.
