Unilateral cross-ownership and emission-reduction technology sharing in a duopoly

This study constructs a Cournot duopoly model that considers unilateral cross-ownership and emission-reduction technology sharing, compares the equilibrium results under different cases, explores the impacts of unilateral cross-ownership and technology sharing, and analyzes the boundary conditions for realizing technology sharing. The results indicate that unilateral cross-ownership has complex effects on the equilibrium results. Emission-reduction technology plays a positive role in improving environmental and social welfare. Furthermore, the boundary conditions of technology sharing were found to be affected by the carbon tax, cost-reduction effect of emission-reduction technology, and cross-ownership.
