Study On Agricultural Green Production Efficiency In China

In recent years,China’s agricultural and rural economic development has made remarkable achievements,but it has also paid a huge price.The problems such as the reduction of cultivated land area,the decline of quality,serious pollution and the shortage of water resources make China’s agricultural development face more and more tight resource constraints.Green development is not only the only way for agricultural and rural sustainability,but also the due meaning of implementing the national concept of green development and realizing rural revitalization.Based on the concept of green development,this paper measures agricultural green production efficiency with agricultural green total factor productivity.Using the national provincial level data from 2004 to 2018,this paper uses environmental production technology,SBM directional distance function,Malmquist Luenberger productivity index and other methods to reasonably calculate China’s agricultural ecological service value,social service value and carbon emission On the basis of carbon absorption level,considering environmental and resource constraints in the traditional agricultural total factor productivity accounting system,scientifically and systematically analyze agricultural green total factor productivity,study China’s agricultural green total factor productivity level,summarize its change track and evolution trend,analyze relevant influencing factors,and identify the key factors affecting the change,The differences of agricultural green production efficiency and spatial convergence between provinces are found.This paper summarizes the important experience and typical models of domestic agricultural green development,and puts forward policy suggestions on accelerating the pace of agricultural green development and practicing the policy of ecological civilization construction.It can be found that in recent years,China’s agricultural green development level has been steadily improved,the agricultural green production efficiency has been continuously improved,and the agricultural production technology has been continuously improved.From 2004 to 2018,the level of agricultural ecological service value and social service value in China was high,showing an overall upward trend,but there were large regional differences.Generally speaking,the ecological service value and social service value of the western region are at the lowest level,while the eastern region and the central region have their own advantages.The ecological service value and social stability value of the central region are the highest,while the social security value of the eastern region is the highest;The overall trend of agricultural carbon budget is stable,the total carbon absorption is slightly higher than carbon emission,and the regional difference is obvious.In terms of agricultural green total factor productivity,the level of agricultural green total factor productivity considering ecological service value and social service value is generally high,but it fluctuates greatly between years and regions.From 2004 to 2018,China’s agricultural green total factor productivity was between 0.7-1.0,showing a fluctuating upward trend on the whole.Among them,the eastern region has the highest agricultural green total factor productivity.Before 2017,the green total factor productivity of agriculture in the central region was higher than that in the west,but after 2017,the central region began to lag behind the West.In terms of changes in agricultural green total factor productivity,the progress of production technology is significantly higher than the improvement of production efficiency in most years.Except for 2004-2005,2006-2009,2010,2012 and2016,agricultural green total factor productivity decreased to a certain extent,and maintained a certain growth rate in other years,indicating the continuous progress of China’s agricultural production technology.From the regional point of view,the change trend of the eastern and central regions is small and generally close.However,the western region has changed greatly,especially in 2013,2015 and 2018,while the eastern and central regions have decreased in the same period.In terms of influencing factors of agricultural green total factor productivity,environmental regulation and economic development are important factors affecting green total factor productivity.The three economic variables of farmers’ per capita net income,per capita financial support for agriculture and environmental problems have a positive impact on the improvement of agricultural green total factor productivity.The results show that,on the one hand,economic factors are important factors affecting agricultural green total factor productivity;On the other hand,the implementation of environmental rules and regulations plays a positive role in agricultural production environment.On this basis,this paper comprehensively analyzes the representative green agriculture development cases in China at the present stage,summarizes the green development model,and puts forward policy suggestions combined with the research conclusions.First,strengthen the research and development of environment-friendly agricultural technology.Technological progress is an important driving force for the change of agricultural green total factor productivity.It is the key to reduce pollution emissions,improve the ecological value,social value and agricultural green total factor productivity of agricultural system,and alleviate the contradiction between agricultural development and resources and environment.It should be actively developed from two aspects of technology and engineering.Second,strengthen the promotion and training of agricultural environment-friendly technologies,and guide more farmers to fully understand the advantages,yield increasing potential and environmental protection of agricultural environment-friendly technologies,so as to effectively reduce the use of chemical fertilizers,pesticides and other chemicals in agricultural production.Third,formulate regional agricultural green development policies.There are great differences in China’s agricultural ecological value,social value and agricultural green total factor productivity among regions,showing obvious regional characteristics.We must formulate agricultural green development policies and reasonably adjust the regional layout of agricultural production according to the natural resource endowment and agricultural structure characteristics of different regions,Promote agricultural specialized production and develop industrial scale and technology suitable for the requirements of agricultural green development.Fourth,improve the system of laws and regulations on rural resources and environment,improve the laws,regulations and institutional norms of agricultural resources and environmental protection that are practical and in line with the principles of market economy,and promote the construction of the standard system of agricultural resources and environmental protection.Fifth,improve the financial policy system for supporting agriculture,accelerate the establishment and improvement of a green and ecological oriented financial policy system for supporting agriculture,build a long-term mechanism for the stable growth of financial investment in supporting agricultural green development,improve the specific operation methods of the paid use system of agricultural resources and environment and the agricultural ecological compensation mechanism in line with China’s national conditions,We will strengthen the supervision system of financial funds for agricultural support for green agricultural development.
