Supply Chain Concentration and Green Innovation Activities of Enterprises——An Empirical Study Based on Panel Data of Chinese Listed Companies

Abstract

Today, China is in an important period from high-speed development to high-quality development. Green development and innovation are important ways for many enterprises to upgrade, transform, enhance their competitiveness and achieve high-quality development. Based on this realistic background, this paper takes the panel data of A-share listed companies in Shanghai and Shenzhen stock exchanges from 2008 to 2019 as the research object, and empirically explores the impact and mechanism of green innovation, an important product feature of enterprise supply chain concentration. The results of this paper show that the higher the concentration of the upstream supply chain of listed companies, the lower their green innovation performance, and the negative effect has always existed and decreased. The further discussion found that the highly concentrated upstream supply chain reduces the input of enterprises' innovation activities and innovation strategy decisions, and thus inhibits green innovation. This paper incorporates green innovation performance and supply chain concentration into the same research system, and theoretically extends the scope of supply chain management research, which has reference and important practical significance for enterprises to carry out green innovation activities and improve their supply chain management and green innovation capabilities.
