Study On Evaluation And Promotion Path Of Agricultural Ecological Efficiency In Shandong Province

Building a strong agricultural country is a major decision anddeployment made at the 20 th National Congress of the Communist Party of China.In order to achieve a strong agricultural country and comprehensively promote the rural revitalization strategy,it is necessary to adhere to solving the "three rural" issues as the top priority in our work.Agriculture is the most fundamental production sector in the nationaleconomy,andthedevelopmentofagriculturalecologyisacruciallinkinagriculturaldevelopment.Agriculturalecologypaysmoreattentionto "resourceconservation" and "environmentalpollution",which means that "only GDP" is no longer suitable for the evaluation of agricultural production in the new era.Thesimpleeconomicoutputvaluecannotspecificallymeasuretheinputandoutputofagriculture,anditis necessary to comprehensively measure agricultural development from the perspectives of economy,ecology,resources and environment.As a major agricultural province in China,Shandong Province ranks first in terms of agricultural output value and plays a crucial role in agricultural production.Therefore,the research on the agricultural ecological development of Shandong Province has significant theoretical and practicalsignificance.Based on the theories of agricultural ecology,sustainable development,and ecological economic system,this article first explains the relevant concepts of agricultural ecological efficiency,and then summarizes and analyzes the current situation of agricultural ecological development in Shandong Province.Secondly,using the SBM model including undesired outputs,select labor,land,pesticides,fertilizers,agriculturalfilm,agriculturalmachinerypower,andirrigationfactorsasinputindicators,takethe total agricultural output value as expected output indicators,and use carbon emissions and agricultural non-point source pollution as undesired output indicators to comprehensively calculate the ecological efficiencyvaluesofvariouscitiesin Shandong Province,andusethistoconstructa Tobitregressionmodel.Select the level of financial support for agriculture,urban-rural income gap Indicators such as agricultural mechanizationlevel,proportionofprimaryindustry,farmland irrigationrate,andindustrialization levelare used as explanatory variables to analyze the influencing factors of agricultural ecological efficiency in Shandong Province.During the analysis process,in-depth research was conducted by roughly dividing Shandong Province into eastern,central,and western regions according to the terrain.The research conclusions are as follows: First,from 2011 to 2020,the agricultural ecological efficiency of Shandong Province gradually improved,with a clear trend and significant progress,indicating that the agricultural developmenttrendin Shandong Provinceisgoodandtheoveralllevelofagriculturaldevelopmentishigh.This is mainly due to the agricultural ecological protection measures taken by Shandong Province in the process of agricultural development.From the data measured by the CRS and VRS models,due to the overall situation of undesired output,the contribution of pure technical efficiency to overall efficiency is limited.Moreover,from the perspective of regional difference analysis,efficiency is uneven,with higher levels in the central region,lower levels in the western region,and a median level of efficiency in the central region.Secondly,based on the analysis of factors affecting agricultural ecological efficiency in Shandong Province,it is found that from 2011 to 2020,there was a significant regional imbalance in agricultural ecological efficiency among 16 cities in Shandong Province.And the effects of relevant influencing factors are significantly different.From the specific empirical results,the level of agricultural mechanization,farmland irrigation rate,and financial support for agriculture,which represent production efficiency,havea significantpositivedriving effectontheagriculturalecologicalefficiency among various cities in Shandong Province.On the contrary,the effect of urban-rural income ratio on agricultural ecological efficiency in Shandong Province is negative.Finally,relevant suggestions are proposed for the conclusions.
