Their model estimates a significant promoting effect at the local level and finds evidence of positive spatial spillovers, meaning that agricultural digitisation in one city is linked with development in nearby areas. The supplied findings do not provide numerical effect sizes or define the geographic structure used to measure those spillovers. Threshold analysis showed that the enabling effect does not follow a uniform, linear pattern.

Instead, the model identifies two thresholds, indicating that the relationship between new quality productive forces and agricultural digitisation changes as conditions vary. The available abstract does not report the threshold values or identify the variables used to define them, so the specific transitions cannot be assessed from the supplied material. Two mechanisms emerged in the analysis: labour skills and innovation capacity both mediate the relationship between new quality productive forces and agricultural digital transformation.

The model therefore links the broader productive forces to local digitisation through pathways involving workforce capabilities and innovation. The findings do not state the contribution of each pathway or establish whether they operate independently. Huang and Guo interpret this variation as a basis for regional coordination, talent cultivation and development suited to local conditions.

The study offers a city-level account of a national-scale process, but the supplied abstract does not detail the model specifications or causal-identification procedures. As a result, the strength of causal inference cannot be evaluated from the abstract alone, even though the study reports a significant promoting effect, positive spatial spillovers, mediation through labour skills and innovation capacity, and a double-threshold pattern.
