本文研究了在气候变化的宏观经济模型中引入内生技术变化对最优CO2减排和碳税水平的影响。我们分析技术变革作为一个功能的累积能力，最近纳入能源系统模型。我们的计算证实，包括内源性创新意味着更早的减排，以满足大气碳浓度的限制。然而，这种影响比文献中提出的要强。此外，发展非矿物能源技术是减少排放的最重要机会。减少化石能源使用的最佳碳税水平低于通常提倡的水平。
This article investigates the impact on optimal CO2abatement and carbon tax levels of introducing endogenous technological change in a macroeconomic model of climate change. We analyse technological change as a function of cumulative capacity, as incorporated recently in energy-systems models. Our calculations confirm that including endogenous innovation implies earlier emission reduction to meet atmospheric carbon concentration constraints. However, the effect is stronger than suggested in the literature. Moreover, the development of non-fossil energy technologies constitutes the most important opportunity for emission reductions. Optimal carbon tax levels, reducing fossil energy use, are lower than usually advocated.
