中文摘要：

减缓气候变化的成本和速度在一定程度上取决于环境友好型技术在降低未来排放方面的潜力。新技术的发明大多首先出现在高收入国家，而温室气体排放不断上升的发展中国家掌握的减排技术很少。因此，气候政策的关键应该在于鼓励向发展中国家转移先进的气候环境友好型技术。首先分析了环境友好型技术的创新和扩散，其次探讨了影响国际技术转移的因素。同时。还回顾了有关环境友好型技术转移的文献，探讨相关研究结果对发达国家和发展中国家环境政策的启示。

英文摘要：

The cost and progress of climate change mitigation to a certain extent oepenu on the environmental-friendly technologies to reduce future emissions. While greenhouse gas （GHG）emissions are projected to rise primarily in the developing countries, GHG mitigation technologies exist primarily in the industrialized countries. Thus, the challenge for climate policy is to encourage the transfer of these climate-friendly technologies to the developing world. This paper firstly analyzes the innovation and diffusion of environmental-friendly technologies, followed by corresponding policies advice to promote international technology transfer. This study also provides an overview of the economic literature on environmental technology transfer, and discusses the implications of empirical evidence for climate policy-making of developing and developed countries.
