Abstract
Knowledge sharing (KS) in the green supply chain (GSC) is jointly determined by the KS efforts of suppliers and manufacturers. This study uses the differential game method to explore the dynamic strategy of KS and the benefits of emission reduction in the process of low carbon (LC) technology in the GSC. The optimal trajectory of the knowledge stock and emission reduction benefits of suppliers and manufacturers under different strategies are obtained. The validity of the model and the results are verified by numerical simulation analysis, and the sensitivity analysis of the main parameters in the case of collaborative sharing is carried out. The results show that in the case of centralized decision-making, the KS efforts of suppliers and manufacturers are the highest, and the knowledge stock and emission reduction benefits of GSC are also the best. The cost-sharing mechanism can realize the Pareto improvement of GSC’s knowledge stock and emission reduction benefits, but the cost-sharing mechanism can only increase the supplier’s KS effort level. In addition, this study found that the price of carbon trading and the rate of knowledge decay have a significant impact on KS. The study provides a theoretical basis for promoting KS in the GSC and LC technology innovation.
Highlights
With the frequent occurrence of extreme natural disasters around the world, climate change caused by excessive CO2 emissions has severely hindered the sustainable development of mankind and threatened ecosystems and biodiversity (Aldieri and Vinci, 2020; Hao and Li, 2020)
This paper mainly studies the impact of Knowledge sharing (KS) on low carbon (LC) technology collaborative innovation and green supply chain (GSC) emission reduction benefits
In order to cope with the phenomenon of knowledge decline caused by rapid technological development, suppliers and manufacturers should collaborate in innovation to reduce the time from R&D to commercial application of LC technologies
Summary
With the frequent occurrence of extreme natural disasters around the world, climate change caused by excessive CO2 emissions has severely hindered the sustainable development of mankind and threatened ecosystems and biodiversity (Aldieri and Vinci, 2020; Hao and Li, 2020). Some countries have set carbon peak and carbon neutral targets. The. Chinese government firmly stated that it will reach the peak of carbon emissions by 2030 and achieve the goal of carbon neutrality by 2060. The US government has made it clear that it will achieve carbon neutrality by 2050. The US federal government has not formulated a specific carbon neutral plan. Some state governments have established relatively complete carbon emission systems and carbon market trading systems, such as the California government. What is certain is that the US carbon neutral path mainly focuses on carbon emission reduction in energy applications, while China is more concerned about carbon emission reduction in energy supply. Regardless of the path, LC technology innovation is the fundamental driving force for achieving the goal of carbon neutrality
