Abstract:

In order to explore the reality of China’s high-quality agricultural development, and realize rural revitalization, agriculture and rural modernization, an evaluartion index system for the development level of high-quality agriculture in China’s major grain-producing areas was established based on the concept of high-quality development and five development concepts. The entropy weight TOPSIS method was used to comprehensively evaluate the agricultural high-quality development level in major grain-producing areas. After that the spatial-temporal evolution characteristics were discussed. The results showed that the level of high-quality agricultural development in main grain-producing areas in China was low and the trend of fluctuation was rising. Meanwhile, Jiangsu had maintained its first position for a long time. The number of medium-high level areas in China’s main grain-producing areas showed an obvious increasing trend. The medium-high level areas expanded from China’s coastal areas to the central region, such as Hubei, Hunan and Jiangxi. The positive agglomeration trend of high-quality agricultural development in major grain-producing areas had continued to increase. Most of the main grain-producing areas had weak connection with each other, showing a trend of isolated development. Hot spots for high-quality agricultural development were shrinking and then expanding. Hot spots had evolved and strengthened from north to south, from the eastern coastal region to the central region. Therefore, it was necessary to adjust the structure of agricultural industry, increase input in agricultural technology, promote regional cooperation in agriculture, and realize green development of agriculture in order to improve the level of high-quality agricultural development in China.

Key words: high-quality agricultural development, major grain producing area, development level, comprehensive evaluation, spatial and temporal evolution
