| Agriculture is the foundation of the country,and this is the foundation of the country.China is a big agricultural country,and agriculture is in a basic position in China’s social and economic development.Agricultural modernization is the key to national modernization.As the ballast stone of agricultural production,the main grain producing areas in China,the development level of agricultural modernization is of great significance to China’s food security and urban-rural integration development.Therefore,this paper measures the development level of agricultural modernization in major grain producing areas of China and studies its temporal and spatial evolution,analyzes the development situation of agricultural modernization in major grain producing areas and puts forward suggestions for further improvement.This paper is carried out according to the basic framework of "theoretical carding-current situation analysis-calculation measure-research on temporal and spatial evolution-summary suggestion" Based on the theory of agricultural location,the theory of agricultural development stages and the theory of sustainable development,this paper uses the data of statistical yearbook from 2011 to 2020,selects the panel data of 13 provinces,constructs an index system including four dimensions of agricultural output modernization,agricultural input modernization,rural modernization and agricultural production sustainability,and uses entropy method to measure and analyze the development level of agricultural modernization in the main grain producing areas of China.Using kernel density estimation,coefficient of variation and Moran index,the temporal and spatial evolution of agricultural modernization development level in main grain producing areas of China was analyzed.The results show that the development level of agricultural modernization in the main grain producing areas of China is 45.3,which is in the initial stage of realization.Regionally,the average development level of agricultural modernization in the three major grain producing areas in China presents the characteristics of "the middle and lower reaches of the Yangtze River > the Huanghuaihai region > the Northeast region",and there are great differences among the three regions and within the region;Judging from the results of coefficient of variation,the agricultural modernization exhibition level of the provinces in the main grain producing areas of China is in a state of coordinated development,and the growth rate of coefficient of variation is gentle,showing a steady downward trend;From the results of nuclear density estimation,the position of nuclear density curve shows a trend of moving to the right as a whole,and the trend of moving to the right is obvious,and the development level of agricultural modernization in the main grain producing areas of China shows an overall growth trend;According to the results of Moran index,the spatial clustering of the development level of agricultural modernization in China’s major grain producing areas is gradually rising from 2011 to 2020,with HH and LL types as the main types within the region,but the provinces with HH-type clustering still have the possibility of further increase.Based on the above conclusions,some suggestions are put forward to further promote the agricultural modernization development in the main grain producing areas of China:(1)adjust measures to local conditions and promote coordinated spatial development;(2)Coordinate and make overall plans to narrow the regional gap;(3)Optimize the allocation of elements and enhance the spatial connection;(4)Give full play to regional advantages and develop characteristic agricultural industries. |
