| Summary: | The evaluation system of China’s high-quality agricultural development is constructed from four aspects: efficiency improvement, innovation-driven, green development, and coordinated sharing, which level is measured based on the entropy weight method (EWM), Besides, using the Theil index decomposition, spatial clustering and convergence theory, this paper analyzes the temporal-spatial evolution characteristics of high-quality agricultural development from 2003 to 2017. The results show that it has obvious spatial agglomeration and convergence in China. First, the quality of China’s agricultural development has steadily improved; besides, the provinces with it are mainly concentrated in the major grain-producing areas in the Northeast Plain and the Yangtze River Basin. Second, it is characterized by conditional convergence in China, and there are also club convergence in major grain-producing areas and non-major grain-producing areas. Third, the conditional convergence rate is 0.067-0.071, the half-life is about 11-12 years, the conditional convergence rate of the main and the non-main production area are 0.095 and 0.075, and the half-life is about 8 years and 10 years, respectively. Finally, combined with the specific statistical indicators, this paper sorted out the reasons restricting the high-quality development of agriculture in various regions and put forward the corresponding countermeasures.
