The optimal quantity decision and complex analysis of duopoly game under low-carbon transformation

This paper explored the equilibrium relationship between technology investment and profit return when the duopoly green transformation. The investment in low-carbon technology can increase profits and provide low-carbon products for society. However, the low-carbon level of products may be reduced simultaneously when both companies undergo a low-carbon transformation. Counterintuitive, by analyzing the feasible region of parameters, it can be found that joint decision-making is not necessarily the best choice. Moreover, we expand the static single-period game to the multi-period game and discuss the complex dynamic behaviors and characteristics.
