Abstract
With the increasing popularity of digital technology in Chinese
enterprises, how digital transformation affects the external green innovation
of enterprises has become a question worth exploring. This study focuses on the
upstream and downstream relationship to explore whether the digital
transformation of downstream enterprises is related to the green innovation
behavior of upstream suppliers under China's "dual carbon" policy. Based on the matching
supply chain data of listed companies in China, the analysis shows that when
the digital transformation of downstream partners is higher, the number of
green patent applications of upstream enterprises is usually higher. The
results of the study show that there is a direct causal relationship, but that
this model is related to changes in the way of information exchange and
coordination within the supply chain, which can reduce the uncertainty of green
innovation activities. This relationship is more obvious in upstream
enterprises in non-heavy pollution industries and enterprises with relatively
strong technological foundations, which may be more flexible in innovative
activities. In summary, the research results show that the digital
transformation within the supply chain may affect the green innovation decision-making
of the enterprise in a way that goes beyond the individual characteristics of
the enterprise.
