我国各省市农业投入与产出的效率评价

EVALUATION OF AGRICULTURAL PRODUCTIVITY IN CHINA BASED ON INPUT-OUTPUT

发展两型社会农业的重要前提就是对农业生产效率进行评价。将DEA评价方法应用于2008年我国31个省市农业生产的效率评价。通过各个省市农业生产的投入与产出数据的分析,发现北京等5个省市农业生产的产出已达到规模最优,农业生产在投入结构上也是技术有效的;我国其它的26个省市农业生产效率还比较低,这些省市农业生产投入结构不够合理。总体上,我国农业生产的技术化程度还不高,在技术效率和规模效率方面需要加强。

The application of Data Envelopment Analysis（DEA） in economic system is virtually probing resource allocation problems.The study employs DEA theory to evaluate agricultural production efficiency of 31 provinces and cities in China in 2008.Via empirical study on input-output data of agricultural production,this paper concludes that Beijing and five other provinces have reached the optimal scale of agricultural production and their investment structure is effective as well;Due to investment in agricultural production structure is not reasonable,26 other provinces and cities are still relatively low in agricultural productivity.Overall,two-oriented society agriculture degree of agricultural production in China is not very high,scale efficiency and technical efficiency need to be improved,to further increase investment in agricultural technology and modernization.
