摘要:

从县域出发,深化主体功能区概念应用,探究土地资源空间配置效率及其管制策略对深化我国国土空间治理体系具有重要意义。通过梳理主体功能区与土地资源空间配置理论关系,借助C-D生产函数考察江苏赣榆主体功能区土地资源空间配置效率,并差别化提出管制策略。研究表明,主体功能区建设实质是“以地为本”,功能区划理念下土地资源空间配置应遵循边际净收益相等的转化度,具有增进用地效率、减少自发优势竞争效率损失的可能。对赣榆区研究发现,不同主体功能区农用地转为建设用地数量存在过量配置,具有帕累托改进空间,其根源在于现行土地计划管理缺乏弹性机制调节指标,造成实际落地中的空间错配。因此,赣榆区应从全区统筹主体功能定位,协调国土空间发展格局,其中优化开发区“革新土地空间结构,转变经济与产业发展方式”、重点开发区“助力城镇工业化进程,确保土地资源利用效益”、限制开发区“着力粮经产品安全,创新农业生产用地经营模式”、禁止开发区“划定生态空间红线,探索农旅生态用地结构布局”。

Abstract:

In terms of the county area, widening the concept application of main functional areas and exploring the spatial allocation efficiency of land resources and its control strategies are of great significance to deepening China's territorial space governance system. This paper combs the theoretical relationship between main functional areas and land resources spatial allocation, the spatial allocation efficiency of land resources in main functional areas of Ganyu district, a typical county-level unit in Jiangsu province, was investigated with the C-D production function, and the differentiated control strategy was put forward. The result shows that the essence of main functional areas construction is "based on land", and land resources spatial allocation should follow the transformation degree of equal marginal net income based on the concept of functional zoning, which makes it possible to improve land efficiency and reduce the efficiency loss of spontaneous competitive advantage. A study of Ganyu district found that the excessive allocation of agricultural land to development land in different main functional areas has the pareto improvement space, which is rooted in the inelastic mechanism of the current land planning management to regulate the spatial land use index, resulting in the spatial mismatch in the actual landing. Therefore, the effective allocation of land resources in Ganyu should be based on the overall planning of main functions and the coordination of land space development pattern, including: optimizing development areas should renovate the spatial structure of land and transform the mode of economic and industrial development; key development areas will contribute to the industrialization of cities and towns and ensure the efficiency of land resources use in the region; restricted development areas focus on the safety of grain and economic products and innovate the management mode of agricultural production land; prohibited development areas draw the red line of ecological space in development zones and explore the layout and structure of agricultural and tourism ecological land.
