| 采用投入强度和技术效率评估方法对陕西省省域、区域、市域不同尺度的耕地开发利用强度和驱动因子进行分析。结果表明：（1）从陕西省单位耕地面积投入要素的强度分化指数P值来看，劳动力和机械投入差距不大（P值分别为0.409和0.649）且在不同尺度上相对均匀，而生物化学要素投入表现出较大的分化特征，化肥、农药和农膜要素的P值分别为0.847、1.026和1.472；（2）从影响因素的解释力q值来看，影响陕西省耕地开发强度分化的驱动力表现为：城镇化率（0.866）>耕地质量（0.855）>农民人均可支配收入（0.551）>耕地地形起伏（0.485）>GDP（0.210）>劳均耕地面积（0.202），社会经济条件和耕地自然基本条件对耕地利用强度的影响高于耕地经营利用因素，且社会经济条件是决定耕地利用强度的主导因素；（3）陕西省87.85%县域的耕地开发强度基本处于最高收益配置，生物化学投入要素是陕西省耕地生产效率的主要限制因素。 |

| In this study, investment intensity and technical efficiency evaluation methods were employed to analyze the intensity of cultivated land development and utilization, as well as the driving factors, across different scales in Shaanxi Province, including provincial, regional, and municipal levels. The results showed that: (1) From the perspective of the intensity differentiation index P value of input factors per unit cultivated land area in Shaanxi Province, there was not much difference in labor and machinery input (P=0.409 and P=0.649, respectively) and they were relatively uniform at different scales. However, the input of biological chemistry exhibited significant differentiation characteristics, with P values of 0.847, 1.026, and 1.472 for chemical fertilizer, pesticide, and agricultural film elements, respectively. (2) Based on the explanatory power (q value) of the influencing factors, the driving forces affecting the differentiation in cultivated land development intensity in Shaanxi Province were ranked as follows: urbanization rate (0.866) > cultivated land quality (0.855) > per capita disposable income of farmers (0.551) > cultivated land topography (0.485) > gross domestic product (0.210) > cultivated land area per laborer (0.202). The influence of socio\|economic conditions and natural basic conditions of cultivated land on the intensity of cultivated land utilization was higher than that of cultivated land management and utilization factors, and the socio\|economic conditions were the dominant factors determining cultivated land utilization intensity. (3) The development intensity of cultivated land in 87.85% of counties in Shaanxi Province was basically in the highest profit configuration, and biological chemistry input factors were the main limiting factors for cultivated land production efficiency in Shaanxi Province. |
