This study explored the spatial disequilibrium of farmland conversion level and its corresponding formation mechanism. In addition, it identified the deciding influence factors of the farmland conversion level of Chongqing and its subordinate area. Based on the panel data of Chongqing City and affiliated 37 districts and counties (excluding Yuzhong District) during 1997-2013, the spatial disequilibrium of farmland conversion level of Chongqing City (China) and its corresponding formation mechanism were analyzed using Dagum Gini coefficient and geographical detector model from an interdisciplinary perspective. The following results were obtained: the farmland conversion level of Chongqing City presented significant temporal-spatial differences. In detail, it was characterized by a spatial pattern of “center-periphery” with region I as the center, region II as the central expansion area, and regions III and IV as the periphery; the reason that the spatial distribution of the farmland conversion level of Chongqing was highly unbalanced mainly owes to interregional differences. The spatial disequilibrium displayed obvious wave-shaped variations during the research period; the formation mechanism of the spatial disequilibrium of the farmland conversion level in Chongqing differed in different districts and counties. The farmland conversion level was subjected to the influences of a variety of complex factors. The factor endowment, economic development level, social development status and policy system environment therein acted as the basic conditions, intrinsic impetus, backbone force and external conditions for the spatial disequilibrium of the farmland conversion level of the research region respectively; the dominant factors affecting the farmland conversion level in different districts and counties were obviously different. In summary, the farmland conversion level of the research region was significantly unbalanced in space due to the influences of diverse factors. Moreover, the deciding factors of farmland conversion level were apparently disparate in different regions. Therefore, it was of great significance to investigate the spatial disequilibrium and corresponding formation mechanism of the farmland conversion level in different regions for the management and control of farmland conversion.
