【摘要】：研究目的:分析土地整治对促进农业现代化水平的影响程度及其区域特征。研究方法:采用基于向量自回归模型的脉冲响应和方差分解法量化土地整治对农业现代化水平的影响,采用因子分析法识别土地整治对农业现代化有显著影响的区域的自然、社会和经济特征。研究结果:(1)从全国层面看,土地整治面积、新增耕地面积和整治投资额对促进农业现代化水平均有正向作用,相应的方差贡献率分别为13.1%、1.1%和8.3%;(2)从区域层面看,在经济发展相对滞后、城镇化水平较低、耕地质量较差、土地开发程度较低的区域,土地整治对农业现代化水平的影响较为显著。研究结论:土地整治对农业现代化水平的提升具有正向作用,但区域差异较为显著,应针对不同地区在自然条件、社会状况、经济发展水平等方面的特征,开展差异化整治,特别是在土地整治对农业现代化提升作用不显著的地区,应对整治方式、后期利用等方面进行反思,慎重开展土地整治工程。
[Abstract]:Objective: to analyze the influence of land reclamation on promoting agricultural modernization and its regional characteristics. Methods: the impulse response based on vector autoregressive model and variance decomposition method were used to quantify the effect of land reclamation on agricultural modernization level, and factor analysis was used to identify the nature of areas where land reclamation had a significant impact on agricultural modernization. Social and economic characteristics The results are as follows: (1) at the national level, land reclamation area, new cultivated land area and renovation investment have positive effects on promoting agricultural modernization, the corresponding variance contribution rates are 13.1% and 8.3%, respectively; (2) from the regional level, In the areas where the economic development is relatively lagging, the level of urbanization is low, the quality of cultivated land is poor, and the degree of land development is low, the impact of land renovation on the level of agricultural modernization is more significant. Conclusion: land regulation has positive effect on the improvement of agricultural modernization level, but the regional difference is more significant. In view of the characteristics of natural conditions, social conditions, economic development level and so on, different renovation should be carried out in different regions. Especially in the areas where land renovation has no significant effect on agricultural modernization, it is necessary to reflect on the methods of land regulation and to carry out land regulation projects carefully.
