Spatial Distribution and Efficiency Evaluation of Agricultural Recycling Economy in Cangzhou City

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.
