Research On The Impact Of Productive Services On The Technical Efficiency Of Corn Production

As one of the most important food crops,corn is the one with the largest planting area and yield,and has a wide range of uses in China.With the continuous advancement of the structural reform of the agricultural supply side,the corn planting area has decreased,but the output has increased steadily,and the unit yield level and production efficiency of corn have increased,which has played an important role in ensuring the domestic corn supply and food security.With the continuous development of urbanization,the proportion of farmers' non-agricultural income is increasing.The advanced agricultural production technology has greatly affected the traditional small-scale agricultural management,which provides opportunities for the development of agricultural productive services.The report of the 19 th National Congress of the Communist Party of China pointed out that "actively promote the agricultural socialized service system and realize the integrated development of small-scale agriculture and modern agricultural development,that is,the future agricultural development will take the agricultural socialized service system as the breakthrough point".Therefore,agricultural productive service is very important for agricultural modernization and scale in China.In this paper,the corn growers in three northeast provinces are taken as the research object.Based on 442 samples of farmers,the current situation of purchasing producer services and the differences of purchasing services in different production links are analyzed.The relationship between agricultural producer services and corn production efficiency is empirically analyzed by using Stochastic Frontier Approach "one-step method".The results show that: first,farmers have a high demand for productive services,and tend to purchase services in part of the production process rather than in the whole process of production;second,due to the different resource endowments of farmers,the choices in different productive services are also different,for example,the older the heads of households,the more non-agricultural income,the larger the operating area,the more land concentrated farmers,the more opportunities There are more productive services in the process of high mechanization and labor demand,and more productive services in the field management for farmers with high education and scattered plots.Thirdly,based on the SFA model,the average technical efficiency score of the sample is 0.932,and the score inclines to the right,indicating that the more productive service links are used,the higher the average technical efficiency is.Fourth,the choice of productive services by farmers has a positive impact on the efficiency of corn production technology,and the impact in different production links is significantly different.The three links of land preparation,seeding and harvesting have a positive impact on agricultural production technology efficiency,and are managed in the field The link has a negative impact on the technical efficiency of agricultural production.Therefore,in order to further promote agricultural productive services and improve the technical efficiency of corn production.First,government departments should strengthen the construction of agricultural productive service system,actively organize technical guidance and training of productive service providers,and vigorously promote agricultural productive services.Second,the agricultural producer service providers should improve their business capacity and the standardization level of each service link in combination with the local situation and the actual needs of their own development.Third,farmers need to improve the sensitivity of access to agricultural information,actively participate in agricultural technology training,and reasonably select agricultural productive outsourcing services in combination with their own needs.
