| 摘 要： | 运用超效率DEA（Super-efficiency Data Envelopment Analysis，SE-DEA）模型建立沧州市农业循环经济效率投入产出指标体系，分析评价了沧州市14个县（市）1995、2000、2005、2010和2014年农业循环经济效率有效性，利用Malmquist指数对各县（市）农业循环经济效率进行动态对比分析，并借助ARCGIS10.0平台，测算并分析各县（市）农业循环经济效率的空间差异及演变规律，并提出改进方案。结果表明，沧州市农业循环经济整体处于较良好水平，各县（市）的综合效率、纯技术效率、规模效率有效DMU占到60%、88.57%和14.29%，多年平均分别在1.216 2和1.449 1和0.938 3左右。综合技术效率空间变化呈现低效双中心由西部向东南部海兴县、东光县过渡的格局。1995—2014年循环农业全要素生产率增长率TFP值都＞1，年均增长率为12.53%。2005—2014年，技术进步是主要促进农业循环经济效率增长的内在动力，综合技术效率下降是制约TPF增长的主要因素。因此，循环型农业作为今后沧州市农业发展的新型模式，提升农业资源的利用效率，推进农业产业化合理经营，确定最优的农业投入产出比，实现生态、经济和社会效益的最大化。

| Abstract: | SE-DEA model was applied to evaluate effectiveness of efficiency of agricultural recycling economy in 14 counties in Cangzhou city during the year 1995，2000，2005，2010 and 2014 with establishment of input-output index system.Malmquist index was used to compare and analyze the economic efficiency of recycling agriculture for counties.Spatial difference and development law of agricultural recycling economy efficiency was calculated and analyzed based on ARCGIS10.0 platform，and improvement plan was put forward.Results showed that overall agricultural recycling economy was positive in Cangzhou city，comprehensive efficiency，pure technical efficiency and scale efficiency efficient DMU in the counties accounted for 60%，88.57% and 14.29%，its average for those were at about 1.2162，1.4491 and 0.9383，respectively.Spatial variation of comprehensive technical efficiency took on double-inefficient center transitioning from the west to the southeast，Haixing county and Dongguang county.Growth rate of total factor productivity （TFP value） was more than 1 from 1995 to 2014，with annual growth rate averaging 12.53%.Technical progress was mainly inner motivation to promote efficiency of agricultural recycling economy from 2005 to 2014，while technical efficiency was the factor restricting the growth of TPF.Recycling agriculture can be insisted for long-term development as a new model in Cangzhou city，it should develop ecological agriculture，manage on a moderate scale for agricultural industry reasonably and enhance utilization of efficiency on agricultural resources and determine the optimal agricultural inputs and outputs，meanwhile，it could maximize the benefits of ecology，economy and society. |
