摘要: Improving comprehensive agricultural productivity is an important measure to realize agricultural modernization. Based on the data from Jilin Statistical Yearbook, this study analyzed the spatial and temporal characteristics of comprehensive agricultural productivity discrepancy in the main agricultural production areas of Jilin Province, China. The comprehensive agricultural productivity of 25 county-level administrative units were evaluated by a comprehensive index system based on five aspects which included 20 indicators from 2004 to 2017. The pattern of the discrepancy was analyzed by the spatial differentiation indices and spatial convergence theory. The results were as follows:1) the overall comprehensive agricultural productivity was in a ‘W-type’ rising trend; 2) the discrepancy was in ‘inverted W-type’ trend; 3) the spatial distribution characteristics were mainly discrete plaque and ‘inverted V-type’; 4) the formation of differences was forced by a combination of internal and external driving forces. Our study demonstrates the effectiveness of rising agricultural productivity and the level of economic and social developments in different counties in Jilin Province.
