Abstract: The sustainable utilisation level of agricultural land resources is closely related to people's lives. In this study, an evaluation method based on double difference method is proposed to analyse the factors affecting the sustainable utilisation level of agricultural land resources. Taking Sichuan Province as the research area, the problems in the process of ecological resources information and land use were analysed. A basic model including explanatory variables, core explanatory variables and control variables is constructed by using double difference method, and the sustainable utilization level under different indicators is evaluated. The results show that the sustainable utilisation level of agricultural land resources in the experimental group considering comprehensive evaluation index is improved by about 1.2% compared with the control group considering only a single evaluation index. At the same time, parallel trend test and process specification model-dynamic integrity dimension (PSM-DID) grouping matching test show that this method has strong robustness.

Keywords: double difference method; agricultural land resources; sustainable utilisation; evaluation model; explanatory variables; control variable.
