基于聚类分析确定评价我国生物柴油企业效率的投入及产出变量的主导因素，建立 CA - DEA 四阶段模型，以排除环境效应和随机误差的影响，准确真实测度效率。选取39家企业进行实证分析，数据调整后，总体上纯技术效率更好，规模效率和综合技术水平较差。结合规模报酬状态普遍处于递增阶段，说明企业管理方面较为成熟且规模普遍偏小。从样本个体来看，个别企业纯技术效率或规模效率大幅下降，表明还需在现有基础上提高管理水平、扩大产业规模。

To excavate the dominant factors based on the cluster analysis,it was identified that the leading factors of the input and output variables about biodiesel enterprise’s efficiency evaluation in China. Establishing the four - stage CA -DEA model is helpful for eliminating the effects of environmental effects and random error on the efficiency value,measur-ing the efficiency of enterprises and management level in a more exact and real way. The empirical analysis chose 39 biodiesel enterprises’efficiency of the various provinces and cities throughout China in 2012. According to the research, after data adjustment,the pure technical efficiency became better,while the comprehensive technical efficiency and scale efficiency fell. Combined the increasing returns to scale in general,it could be illustrated that the management in the biodiesel enterprise was more mature and the scale was generally small. Based on the individual sample,a small quantity of enterprises’pure technical efficiency or scale efficiency dropped sharply. It indicated that,on the basis of the existing foundation,it was necessary to improve the management ability and to expand the scale of the industry.
