With the development of the green food industry, land conflicts are gradually escalating, and the coordinated development of competitiveness level and land use efficiency is crucial to the green food industry. The competitiveness level of China’s green food industry at the provincial level between 2011 and 2020 was measured by constructing an index system using the entropy method and VlseCriterion Optimisation and Compromise Resolution (VIKOR) method, and then the land use efficiency was evaluated using the super efficiency Slacks-based Measurement (SBM) model, and the coupling coordination degree was analyzed using the coupling coordination model based on the results of both measurements. The results showed that the competitiveness level of the green food industry was “high in the west and low in the east”; most provinces and cities were with the middle competitiveness level. Land use efficiency generally showed a trend of rising and then falling and leveling off, and the average value of the three regions was ranked as eastern (1.13) > western (0.84) > middle (0.63). The mean value (0.82) of the overall coupling coordination in China floated at the boundary of high-quality coordination, and all three regions showed a trend of rising and then falling and leveling off, and the number of provinces and cities in high-quality coordination in China was shifting from the north to the south during 2011–2020. This study can provide theoretical support for the coordinated development between industrial development and land use, and provide feasible suggestions for the intensive and efficient use of resources.
