北京市从2004年起实施的粮食补贴政策,对稳定粮食生产和提高农民收入作用显著。补贴资金投入能否有效地获得产出是补贴政策制定者所关心的一个问题,科学测算资金投入的效率能够为政策的优化调整提供理论依据。本研究首先梳理了北京市粮食补贴政策的资金投入情况,然后基于DEA模型的投影分析测算了北京市粮食补贴政策资金投入的投入冗余和产出亏空。结果表明北京市粮食补贴资金投入的效率较高,但通过优化补贴结构、创新补贴项目等方式存在进一步提升的空间。 The grain subsidy policy implemented by Beijing Municipality since 2004 has played a significant role in stabilizing grain production and raising farmers’ incomes. Whether the input of subsidy funds can get the output effectively is a question that the subsidy policy makers care about. Scientifically calculating the efficiency of the capital investment can provide the theoretical basis for the optimization and adjustment of the policy. This study firstly combs the capital investment of Beijing Grain Subsidy Policy, and then based on the projection analysis of DEA model, it estimates the input redundancy and output deficit of Beijing Grain Subsidy Policy. The results show that the capital subsidies for food in Beijing are more efficient, but there is room for further improvement through such measures as optimizing the structure of subsidies and subsidizing innovative projects.
