Abstract:

It is of great significance to study the coordination relationship between agricultural green production and new urbanization including carbon absorption from the perspective of low carbon to achieve the goal of agricultural green development and urban-rural integration. Based on the super-efficiency SBM model and entropy method, the agricultural green production efficiency and new urbanization level of 17 provinces (autonomous regions, municipalities directly under the central government) along the Silk Road Economic Belt from 2002 to 2021 were calculated, and the coupling coordination model was used to study the coupling and coordination relationship between the two. The results showed that during the sample period, the new urbanization level in the Silk Road Economic Belt showed that the eastern region was better than the western region, and the growth of agricultural green production efficiency depent more on the progress of agricultural technology. The coupling coordination degree of the system increased steadily during the study period, and in recent years, it showed the spatial distribution pattern of southeast>northwest>southwest>northeast. Finally, combined with the grey GM (1,1) model to predict the change trend of the coupled system of the Silk Road Economic Belt in 2022-2032, it is found that the southeast, northeast, southwest and northwest regions will enter the coupled coordination stage in the future, and the regional differences in space will continue to be maintained. Therefore, policy suggestions such as raising the level of new-type urbanization, strengthening agricultural green science and technology innovation, and establishing regional cooperation mechanisms are put forward.
