Abstract:

The large-scale transfer of agricultural population to cities and secondary and tertiary industries causes other agricultural production factors to change, ultimately affecting the efficiency of cultivated land use. In this study, 11 cities in Jiangxi Province were used as research areas. The super-EBM (Epsilon Based Measure) model was used to measure the utilization efficiency of cultivated land from 2007 to 2016. On this basis, taking the proportion of agricultural transferred population in agricultural population as the threshold variable, the impact of agricultural population transfer on farmland utilization efficiency was analyzed through the panel threshold model. The study indicates that during the inspection period, the agricultural transfer population and the cultivated land use efficiency of the cities in Jiangxi Province showed an upward trend, and the regional differences were significant. In 2016, the impact of agricultural population transfer on the efficiency of cultivated land utilization in most cities of Jiangxi Province showed a threshold effect. Before and after the threshold value (0.428), agricultural population transfer always promoted the efficiency of cultivated land use, but its impact coefficient decreased from 0.5089 to 0.2495. The promotion effect is reduced by 51%. According to whether the degree of agricultural population transfer is across the threshold, the countermeasures for improving the utilization efficiency of cultivated land for different regions are proposed.

Key words: agricultural population transfer, land use efficiency, panel threshold model, super-EBM (Epsilon Based Measure) model, Jiangxi Province
