基于脱钩理论的建设占用耕地与经济发展关系研究——以安徽省为例

目的]对安徽省建设占用耕地与经济发展的脱钩情况进行分析,旨在为安徽省实行差别化土地政策提供理论依据。方法]基于脱钩系数框架,以安徽省2002—2013年建设占用耕地变化情况为基础,采用省级时间序列开展。依据2013年各市脱钩系数差异对安徽省的16个地市进行区域划分,详细剖析不同区域的脱钩特点及其形成原因。结果]安徽省建设占用耕地与经济发展脱钩状态在时间上呈现波动态势,其中农业经济发展与建设占用耕地偏强脱钩型,非农经济与建设占用耕地的脱钩态势仅仅在2005—2007年出现好转迹象,从2008年开始均出现反弹现象;2013年的脱钩情况在区域间存在明显差异性,且脱钩类型分布情况与区域产业分工情况之间存在较强对应关系。结论]政府应加强对建设占用耕地的审批和监管力度,加大对现代农业的支持力度,提高耕地的利用率和产出率,积极推进产业结构调整和主体功能区建设,从而实现建设占用耕地与经济发展的强脱钩。

Relationship Between Cultivated Land Occupied by Construction and Socio-Economic Development Based on Decoupling and Re-coupling Theory -A Case Study in Anhui Province

Objective] The decoupling evolution of the construction of the land and economic development in Anhui Province was analyzed to provide theoretical basis for implement differentiation of land policy in Anhui Province. Methods] First, time-series data were used to explore the evolution of decoupling between the cultivated land occupied by construction and economic development of Anhui Province in 2002 to 2013. Then, regionalization of 16 cities was conducted in Anhui Province according to their decoupling coefficients. Then a detailed analysis of the decoupling characteristics of different regions was made and the corresponding causes were given. Results] Decoupled state of the cultivated land occupied by construction and the economic development in Anhui Province fluctuated over time. The decoupling between agricultural economic development and the cultivated land occupied by construction belonged stronger decoupling type. The situation of decoupling between non-farm economy and the cultivated land occupied by construction was not optimistic, it got slight improvement in 2005-2007, but rebounded from 2008 on. There was obvious regional differences in decoupling between the cultivated land occupied by construction and the economic development. And there was a strong correspondence between the distribution of decoupling type and regional industrial division. Conclusion] The government should strengthen the supervision of the construction approval of the cultivated land occupation, and other measures as to increase the support for modern agriculture, to improve the efficiency and productivity of arable land, and to actively promote industrial restructuring and the construction of the main functional areas. All these measures are helpful to achieve the strong decoupling between economic development and the cultivated land occupation by construction.
