国内外光伏产业政策绩效对比研究

The International Comparison of Policy Performance in Photovoltaic Industry

本文从政策绩效角度,应用三阶段的DEA和聚类分析对18个国家的光伏产业政策绩效进行了定量研究。结果显示:1外部环境因素对各国光伏产业政策效率有一定的影响,规模效率低是政策效率较低的主因;2中国和德国的光伏产业虽然利用规模较大,但出现了规模不经济;318个国家的光伏产业政策绩效可分为三类,一类:德国、美国和日本等11个国家,政策效率处于相对较高的水平;二类:中国、法国和马来西亚,政策效率处于相对中等的水平;三类:奥地利、比利时、加拿大和丹麦,政策效率处于相对较低的水平。最后,依据实证分析的结果提出了一些建议。

From the perspective of policy performance, this study uses three-stage DEA and cluster analysis to evaluate policy efficiency in photovohaic industry among 18 countries. （1）External environment factors have a certain influence on PE, low scale efficiency is the main reason that leads to a low policy efficiency. （2）The utilizing scale of photovohaie industry in China and Germany is larger, but the scale is not economic. （3）According to policy efficiency, 18 countries can be divided into three categories, the first category： 11 countries such as Germany, United States and Japan, the policy efficiency is at a relatively high level; the second category： China, France and Malaysia, PE is at relatively moderate level; the third category： Austria, Belgium, Canada and Denmark, PE is at a relatively low level. Finally, it puts forward some suggestions based on the empirical analysis of the results.
