Abstract:

This paper constructs an interpretive framework for the input-output of cultivated land among farmers with different scales of operation, utilizing survey data from farmers in the peripheral areas of desertification in four prefectures of Southern Xinjiang. By employing the Super-SBM model for unexpected outputs and the Tobit model, the study analyzes the efficiency of cultivated land use and its influencing factors among farmers. The results indicate that: (1) There is a significant difference in the input-output of cultivated land among farmers in desertification areas based on their operation scale, with medium-scale farmers having relatively lower unexpected outputs, which is more conducive to desertification prevention and control; the comprehensive technical efficiency value of farmers' cultivated land is relatively low, with the pure technical efficiency value being only 43.36% of the scale efficiency value. (2) The probability function curves of the pure technical efficiency value and scale efficiency value for farmers' cultivated land show an increasing and then decreasing trend with the expansion of cultivated land area, with the pure technical efficiency value (1.1 hm2) reaching its peak faster than the scale efficiency value (4.4 hm2). (3) Medium and large-scale farmers are affected by the most factors, with medium-scale farmers being influenced by variables such as input in cultivation, age of labor force, employment status, ethnicity, etc., while large-scale farmers are also affected by their preference for cultivated land protection. Policies for desertification prevention and control need to incentivize peripheral farmers to transition towards intensive farming practices, focus on moderate scale operations, timely assess the impact of cultivated land transfer systems and changes in management methods on desertification prevention and control, vigorously promote digital agricultural technologies, reduce agricultural non-point source pollution and over-extraction of groundwater, strengthen training in language and skills for the labor force, and promote the green development of cultivated land in the peripheral areas of desertification.
