摘要：

生产效率是竞争力的一种体现，评价中国绿茶种植的生产效率，对中国茶产业的发展有重要意义；本文选用DEA方法，将中国绿茶十个主产省作为决策单元，对中国十省绿茶种植投入产出的有效性进行了评价；一方面得出浙江等省绿茶生产为非DEA有效，并分析了各非DEA有效单元原因所在，从规模来看，各决策单元都处于规模报酬递增阶段；另一方面根据投影分析测算了各单元投入冗余量；最后为茶农优化茶叶生产决策提出了建议。

Abstract:

Productivity is a reflection of the competitiveness. Evaluating the production efficiency of green tea plantings in China is important to the development of tea industry in China. In this paper the DEA method was used to evaluate the input-output efficiency, the ten main producing provinces of China green tea as a decision-making unit. One side, from the DEA analysis the production of green tea such as Zhejiang province is non-DEA efficient and the reasons of non-DEA efficient units, each unit is increasing returns to scale; on the other side, the input redundancy was calculated according to the analysis of projection. Eventually, several propositions and policies were derived for the improvements of farmers’ production decisions.
