供应链集中度对专精特新企业创新效率的影响研究

Research on the Impact of Supply Chain Concentration on Innovation Efficiency of Specialized,Elaborative,Characteristic and Innovative Enterprise

企业与主要供应商和客户在合作中相互产生嵌入性行为可为专精特新企业创新带来新的发展契机。本研究从关系嵌入性视角出发,同时考虑供应商集中度和客户集中度,以2017—2021年中国专精特新上市企业的样本数据为例,探究供应链集中度对专精特新企业创新效率的影响,以及企业规模和行业竞争度的门槛效应。研究发现:①供应商集中度和客户集中度均正向促进专精特新企业创新效率;②在供应商集中度与专精特新企业创新效率的门槛效应分析中,企业规模的门槛具有单一性和双重性,而行业竞争度仅有双重性;③在客户集中度与专精特新企业创新效率中,企业规模存在单一门槛效应,行业竞争度则存在单一和双重门槛效应。本研究为企业供应链管理与专精特新企业创新决策的制定提供依据。

The embedding behavior between enterprises and major suppliers and customers in cooperation can bring new development opportunities for innovation in Specialized,Elaborative,Characteristic and Innovative enterprises.This paper considers the view of relational embeddedness and incorporates supplier concentration and customer concentration into a unified analysis framework by using the Specialized,Elaborative,Characteristic and Innovative enterprises from 2017 to 2021 as sample enterprises to explore the impact of supply chain concentration on the innovation efficiency and the threshold effect of enterprise size and industry competition degree.The conclusion indicates the following.①Both supplier concentration and customer concentration have significant positive impact on the innovation efficiency of Specialized,Elaborative,Characteristic and Innovative enterprises.②In the analysis of the threshold effect between supplier concentration and innovation efficiency of sample enterprises,the threshold for enterprise size has a single and double threshold effect,while industry competition only has a single threshold effect.③In terms of customer concentration and innovation efficiency of sample enterprises,there is a single threshold effect for enterprise size,while there are single and double threshold effects for industry competition.The research conclusion provides empirical guidance for supply chain management and the formulation of innovative decision-making for Specialized,Elaborative,Characteristic and Innovative enterprises.
