Abstract:

Stimulating enterprises to spontaneously adopt low-carbon technologies by utilizing market-based means is regarded as a way that is more in accordance with the theory of enterprise behavioral decision-making. However， the environment of corporate investment and decision-making increasingly complex under the coupling effects between electricity market and carbon trading market. The change is prone to inducing the risk of rising transaction costs， which affects the dynamic process of low-carbon technology diffusion. Therefore， a coal-fired power enterprises low-carbon technology diffusion decision-making model is constructed based on complex social network and the profit-driven logic. Based on the behavior logic driven by enterprise profit motives， a decision-making model is constructed for low-carbon technology diffusion in coal-fired power enterprises within complex social networks. This explores how market mechanisms and policy tools can be effectively combined under the linkage of electricity and carbon markets to promote the low-carbon transition of coal-fired power enterprises. It is found that an increase in the number of independently decision-making enterprises aids in accelerating technology diffusion； there are significant differences in the impact mechanisms of market incentives on different types of low-carbon technologies， and relying solely on the current internal synergy of the electricity and carbon markets is insufficient to promote the diffusion of carbon capture technologies. Furthermore， differentiated policies and intrinsic carbon pricing mechanisms can steadily advance the diffusion of low-carbon technologies while avoiding transaction risks induced by jagged fluctuations in annual carbon emissions curves.
