The efficiency evaluation of food financial subsidy policies to Food Quantitative Security

We must consider not only the effect of policies, but also their costs on the study of food financial direct subsidies´ efficiency. This paper utilize DEA model which is researched the standard efficiency problem evaluate Chinese current food financial direct policies to Food Quantitative Security with system efficiency and technological efficiency. We can get the basic conclusions, which include: System effective provinces concentrated in most major grain producing areas, and non-effective provinces concentrated in rapid economic developmental provinces and poor provinces. System effective provinces are all scale effective. And the return to scale of non-effective provinces is increasing. The analysis of the ineffective provinces´ slack variable shows that there is a definite relation between input redundancy and output shortage of food subsidies, and improving efficiency is changing from the non-efficient cause, such as fair use of Subsidy for planting superior crop varieties, subsidy for farm machinery purchase, food comprehensive subsidies´ standard, rice well-bred subsidies´ standards. This will directly affect the increase of the total grain output, per capita amount of gain, and the farmers´ enthusiasm.
