考虑碳减排成本的内生经济增长路径研究

The Optimal Endogenous Economic Growth Considering the Abatement Cost of Carbon Dioxide Emissions

为了分析碳减排对内生经济增长的影响,将碳减排比例引入生产函数,将对气候变化的警惕意识引入效用函数,建立了考虑碳减排成本的内生经济增长模型,比较分析了各参数对经济增长路径的影响.长期来看,碳强度、碳减排比例与经济增长之间呈负向关系.低碳技术应用越广泛,研发成果对技术积累贡献率越大,消费者对当前消费的偏好程度越小,人们对气候变化的警惕意识越强,越有利于经济可持续发展.

In order to analyze carbon dioxide abatement impact on the endogenous economic growth, the rate of carbon dioxide abatement was put into the production function. Alert awareness towards climate change was put into utility function. An endogenous economic growth model of considering the abatement cost of carbon dioxide emissions was established. The influence of various parameters on path of the optimal economic growth was analyzed. In the long term, carbon dioxide emissions intensity and rate of carbon dioxide abatement have mutual negative linear relationship with economic growth. Widely using low carbon technology, improving the contribution of technology accumulation from research and development, reducing preference to the current consumption, and strengthening awareness towards climate change would be beneficial to promote economic sustainable development.
