Studying the law of spatiotemporal evolution of agricultural total factor productivity is of great significance to formulate the agricultural transformation and upgrading policies rationally. This paper, which is based on the calculation of agricultural total factor productivity growth from 37 counties in Chongqing over the period 2000-2016 by using DEA-Malmquist index model, investigates characteristics of spatiotemporal evolution of agricultural total factor productivity by using spatial analysis and Kernel density estimation methods and identifies the problem regions of Chongqing. The results are listed as follows: (1) From 2000 to 2016, the agricultural total factor productivity is on the rise. The agricultural total factor productivity index has a tendency of "U" type and periodic fluctuation, which shows obvious spatial imbalance. (2) The change trend of agricultural total factor productivity index is similarly consistent with that of technical progress index, which indicates that the technology progress is the main reason for total factor productivity growth. (3) From the view of the whole city, the Kernel density curve of agricultural total factor productivity keeps moving to the right, and the crest height continues to rise. The crest shape changes from "unimodal" to "multi-modal" distribution, which implies that the regional disparity of agricultural total factor productivity shows an increasing trend during the study period. (4) According to the relationship among agricultural total factor productivity growth, technical progress and technical efficiency, three types of problem regions are identified. Then policy suggestions for agricultural transformation and development are proposed for each type of problem region.
