Research On The Coordinated Development Of Agricultural Structure Optimization And Agricultural Modernization In Main Grain-producing Areas

Since 2012,China's grain output has been stable at more than 600 million tons for years.In 2018,China's per capita grain supply reached 477.21 kg,exceeding the world average.The self-sufficiency rate of rice,wheat and corn has been kept above 98 percent,which is largely attributable to the major grainproducing areas.However,for a long time,China has mainly ensured food security by increasing grain output and enhancing grain production capacity,ignoring the important supporting role of output capacity of main grain-producing areas,agricultural industrial structure and agricultural comprehensive competitiveness to food security.The grain output in major grain-producing areas is increasing,but the agricultural economic benefit is low,and the economic level is more and more backward compared with the non-major grain-producing areas.A series of problems are particularly prominent in major grainproducing areas,such as farmers increasing production but not increasing income,the contradiction between supply and demand of agricultural products,and the unreasonable structure of agricultural industry.It is an important development strategy for China at present and for a long time to come to promote the coordinated development of agricultural industrial structure optimization and agricultural modernization.In essence,agricultural modernization and agricultural industrial structure optimization are internally unified,mutually coordinated and mutually promoted.Agricultural modernization is an important basic guarantee for optimizing agricultural industrial structure,and agricultural industrial structure optimization is a booster for developing agricultural modernization,which can effectively drive the development of agricultural modernization.Coordinating and promoting the optimization of agricultural industrial structure and the development of agricultural modernization is of great significance to ensuring food security and meeting consumer demand.Henan province,located in the central plains of China,is not only a big traditional agricultural province,but also an important main grain producing area in China.This study takes Henan province as a typical province to study the agricultural modernization and the optimization of agricultural industrial structure in the main grain-producing areas.Firstly,the overall situation of major grain-producing areas,optimization of agricultural industrial structure and development level of agricultural modernization in Henan province were studied.Second,to develop the agricultural industry,agricultural industry structure adjustment and agricultural industry integration as the subsystem of the degree of evaluation of the agricultural industry structure optimization,selection of agriculture modernization,modernization of agricultural production,rural social economic modernization and agricultural ecological modernization as the subsystem of the evaluation of agricultural modernization,on this basis,with the variation coefficient method to determine weights,using multi-objective linear weighting method,for major grainproducing areas as a whole and degree of agriculture industry structure optimization in henan province and evaluate the level of agricultural modernization;Again,use coordination degree model,to the agricultural industrial structure optimization and the measure and evaluation on the coordinated development of agricultural modernization,summarizes the major grain producing areas and henan province agriculture industrial structure optimization and the space-time evolution characteristics of the coordinated development of agricultural modernization,to explore the major grain producing areas and henan province agriculture industry structure optimization and coordinated development of agricultural modernization constraints;Finally,based on the research conclusions,the overall level of major grainproducing areas and the development direction of agricultural industrial structure optimization and agricultural modernization in Henan province are proposed.
