基于熵值法和DEA的农业循环经济发展水平评价研究

The research on evaluation of the agricultural circular economy development level based on the entropy value and the DEA method

摘要:

采用熵值法与DEA相结合的评价方法对我国1993年至2011的农业循环经济发展水平进行了评价。通过将熵值法与DEA相结合,克服了现有研究对于多指标赋权问题人为主观赋值的弊端,同时兼顾了总体评价和效率评价全面分析,实现了完全采用客观求权重的方法评价农业循环经济发展水平。分析结果表明,农业循环经济发展水平的提高与资源减量子系统和社会经济发展子系统的良好运行有着紧密的联系,而循环利用子系统和生态环境子系统的贡献较小,这是今后发展农业循环经济应该高度重视的方面,除此之外,我国农业循环经济发展水平存在效率低下,常年存在投入过剩和产出不足的情况。最后给出了政策建议。

Abstract:

The entropy value method combined with DEA evaluation method is used to evaluate the agricultural circular economy development from 1993 to 2011 in China. By combining the entropy value method and DEA, realized fully adopting the method of objective weights for evaluation of agricultural circular economy development level, overcomed the disadvantages of subjective assignment for more weighting of existing research, and took full account of comprehensive evaluation and efficiency evaluation. The results showed that good operation of resources reducing subsystem and the social and economic development subsystem is closely linked to the improvement of agricultural circular economy development. Meanwhile, contributions of the recycling subsystem and ecological subsystem environment are still small, it should attach great importance to the development of agricultural circular economy. In addition, the efficiency of agricultural circular economy development level is low, because the shortage of perennial excess exists between inputs and outputs. Finally, gives the policy suggestions.
