中文摘要：

基于2004—2013年我国可再生能源投资、经济总量、产业结构、能源效率、碳排放量等相关数据,运用调节效应模型、状态空间模型等,测量了可再生能源投资总量和结构对碳排放的作用并比较了差异性;在此基础上以上网电价政策为例,进一步分析了可再生能源投资政策对碳减排的引导性。结果显示：（1）可再生能源投资对碳排放没有直接的影响,但通过经济总量和能源效率路径均产生了碳拉动作用;通过结构路径,可再生能源投资总量和结构对碳排放分别产生拉动和抑制作用;（2）考虑单一路径时,投资结构对碳排放的影响较大,而综合考虑多个路径时,投资总量的碳抑制效应优于投资结构;（3）长期内,可再生能源投资通过产业结构与能源效率对碳排放的作用受阻,但通过能源结构路径对碳排放产生了明显的抑制作用,且其抑制作用大于系统中的碳拉动作用;（4）通过分析风电产业的标杆电价政策,发现现有政策对可再生能源投资的碳减排作用具有引导性。

英文摘要：

Based on the data of renewable energy investment, economic gross, industrial structure, energy efficiency, carbon emissions, etc. In the period of 2004-2013 of China, with the methods such as the regulatory effect model and the state space model, this paper estimates and compares the differences of impact of the total investment amount and the structure of the renewable energy on carbon emissions. Besides, by taking the feed-in tariff policy as an example, we further analyse the guidance of renewable energy investment policy for carbon emissions. The research shows that firstly, renewable energy investment amount and structure has no direct impact on carbon emissions, but has carbon-pulling effect through influencing economy aggregate and energy efficiency; besides, through structure channel, the total amount and structure of renewable energy investment respectively results in pulling and depression effect of carbon emissions. Secondly, in terms of the single path, the investment structure has a great impact on carbon emissions, while in terms of the multiple paths comprehensively, the carbon depression effect of the total investment is superior to that of the investment structure. Thirdly, the industrial structure and energy efficiency channel is block in the long term, but through influcing the energy structure, there is significant carbon depression effect of renewable energy investment; and the carbon depression effect is greater than the pulling effect in system. Fourthly, through analyzing the effect of ＂wind power industry benchmark price policy＂, we prove the guidance of existing policy of renewable energy investment for carbon reduction.
