基于OECD政策分类的国际农业支持政策绩效分析

Analysis of the performance of international agricultural support policy based on OECD classification standard

摘要:

本文基于OECD农业支持政策体系分类,采用数据包络分析法,从时间维度,评估18个国家以及欧盟农业支持政策绩效,分析农业支持政策绩效的时序变化规律,探索我国农业支持政策优化路径。计算结果表明,18个国家中日本、新西兰始终保持DEA有效,且规模报酬保持不变。冰岛和智利的综合技术效率最低,2012年仅为0.001,说明其农业支持规模和农业生产规模的优化程度、配置比例较低。从时间的角度来看,各国纯技术效率不断提升而规模技术效率有所下降。由于各个国家的国情不同,纯技术效率与规模效率均有很大的差异。75%的国家处于规模收益不变或递增状态。投入冗余部分主要在纯技术效率方面,且随着时间的推移,投入冗余逐年减少。我国农业支持政策绩效较低的主要原因在于投入、产出不足。

Abstract:

Based on the agricultural support policy system according to the OECD classification standard, this paper evaluated the performance of 18 national agricultural support policy and European Union agricultural support policy ,analyzed the performance of agricultural support policy by using the Data Envelopment Analysis (DEA) in the perspective of time. At the same time, taking advantage of the GIS technology, summarized the spatial-temporal characteristics of the agricultural support policy performance in order to seek the optimization path of China agricultural support policy. It is shown that among the 18 countries just Japan and New Zealand maintain the effectiveness of DEA, and the returns to scale remains unchanged. The crste efficiency in Iceland and Chile is the lowest overall, in 2012 was only 0.001, indicating the optimization degree of its agricultural support scale and the allocate proportion of it to the agricultural production scale are low. In the view of time, vrste efficiency continuously upgrade, but the scale efficiency decreased. Due to the various situations in different countries, the differences in vrste efficiency and scale efficiency are greatly. The 75% countries are in constant returns to scale or increasing state. Redundant input mainly in vrste efficiency, as the passing of time, redundant input reducing. The main reason of China’s agricultural support policy performance is low is the shortfall input and deficiency output.
