Research On The Impact Of Agricultural Productive Services On Grain Production Efficiency In Henan Provinc

People’s food is the foundation of the economy,and food security is the cornerstone to ensure rapid and stable economic development.As a service provider of food production,agricultural productive services are an important driving force to promote resource conservation and improve food production,and the degree of their development will have a profound impact on food production efficiency.Therefore,how to use productive services to improve grain production efficiency in Henan Province has become an urgent problem to be solved at present.This paper uses the theory of labor division and production frontier theory to analyze the favorable conditions for the development of producer services in Henan Province.This paper firstly explains the characteristics of grain production in Henan Province,then analyzes the regional changes of grain production,and finally describes the grain production characteristics of various cities.Based on the data from the 2011-2019 "Henan Provincial Statistical Yearbook",the DEA-SBM analysis was carried out to calculate the agricultural grain production efficiency of Henan Province;Then take the grain production efficiency of Henan Province as the dependent variable,agricultural productive services as the main variable,labor supply services and financial support services for agriculture as the control variables,using stata16.0 to explore the impact of agricultural productive services,labor supply services and financial support services on grain production efficiency in Henan Province.This paper innovatively adopts macro data to find out the input status of food production by calculating the weight,and then explores the influence of input factors in productive services on the comprehensive technical efficiency of food production,hoping to supplement the lack of research in related fields to some extent.Through exploring the influencing factors of agricultural productive services on grain production efficiency in Henan Province,this paper draws the following conclusions: the grain production efficiency in Henan Province is higher in the sample range,but the efficiency of different cities has its own characteristics.Xinyang City,Kaifeng City and Shangqiu City need to increase scientific and technological investment to improve the utilization of production factors,while Zhoukou City,Zhumadian City,Sanmenxia City and Xinxiang City need to appropriately expand the production scale,Optimize the production scale close to the production frontier.The subdivided industries of agricultural productive services,such as agricultural financial services and agricultural machinery services,agricultural marketing services and agricultural circulation services,will have an impact on the grain production efficiency of Henan Province,indicating that the improvement of these industries can effectively improve the grain production efficiency of Henan Province.
