中文摘要:
      基于耕地利用生态效率的内涵界定,运用DEA效率混合测度模型和协调发展度模型,分析2001—2016黑龙江垦区耕地利用生态效率及其非效率来源,探究耕地利用生态效率的内部协调性。研究表明:2001—2016年研究区耕地利用生态效率呈波动上升趋势,变化幅度不大,各管理局耕地利用生态效率差异明显;耕地利用效率损失的主要原因为投入非效率、社会产出非效率和环境产出非效率,且投入非效率普遍高于社会产出非效率和环境产出非效率,耕地投入冗余对耕地利用效率的负向影响最大;耕地利用经济和社会效率相对于环境效率滞后,是影响耕地利用生态效率内部协调性的主要原因。认为耕地利用生态效率是耕地利用经济、社会和环境效率的综合体现,并从内生性角度分析耕地利用非效率来源及其变化趋势,为提高耕地利用效率提供有效指导,即通过优化研究区耕地投入结构,减少耕地投入冗余,提升其耕地利用经济和社会效率,以实现耕地利用经济、社会和环境效率的协调发展。
英文摘要:
      Based on the definition of eco-efficiency of cultivated land use and application of DEA efficiency mixed model and coordinated development degree model,this paper analyzed the eco-efficiency and non-efficiency sources of cultivated land use in Heilongjiang reclamation area from 2001 to 2016,so as to explore the internal coordination of the eco-efficiency.The results showed that:(1) From 2001 to 2016,the eco-efficiency of cultivated land use in study area showed a slight upward fluctuation with obvious differences among various administrative bureaus.(2) The main reasons for the loss of efficiency in the study area included inefficiency in input,social output and environmental output,with the former remarkably higher than the rest two.The input redundancy had the greatest negative impact on cultivated land use efficiency.(3) Compared with environmental efficiency,the lag of economic and social efficiency affects the internal coordination of eco-efficiency of cultivated land use.The eco-efficiency of cultivated land use is the comprehensive embodiment of the economic,social and environmental efficiency.Exploring the sources and trends of inefficiency from the endogenous perspective,this paper provided measures to improve the efficiency,mainly including to optimize the structure of cultivated land input in the study area,to reduce the redundancy of cultivated land input,and to improve the economic and social efficiency of cultivated land use so as to achieve the coordinated development of economic,social and environmental efficiency.
