中国农村土地交易效率测度及其空间分布特征研究

Study on the Measurement of Rural Land Transaction Efficiency and Its Spatial Distribution Characteristics in China

运用加入时间变量的熵值法对中国农村土地交易效率进行测度,并借助探索性空间数据分析法探究农村土地交易效率综合指数及其一级指数的空间分布特征。结果表明:中国农村土地交易效率整体呈上升趋势,但土地供给是其关键薄弱环节;各省域之间农村土地交易效率差异显著,且均存在与地区特征相匹配的优势与短板;农村土地交易效率综合指数及其一级指数在空间上呈现不同程度的集聚特征,主要表现为“高-高”“低-低”二元分布模式。据此,应坚持完善农村土地交易市场,加大农业基础设施投入力度,优化农村土地投入要素,进一步深化农村土地资源配置改革,因地制宜制定农村土地交易效率提升策略。

This paper uses the entropy method with time variables to measure the efficiency of rural land transaction in China,with the help of exploratory spatial data analysis method to explore the spatial distribution characteristics of the comprehensive index of rural land transaction efficiency and its primary index.The results show that the overall efficiency of rural land transaction in China shows an upward trend,but land supply is the key weak link.There are significant differences in rural land transaction efficiency among provinces,and there are advantages and weaknesses that match the regional characteristics.The comprehensive index of rural land transaction efficiency and its primary index show agglomeration characteristics in varying degrees in space,mainly in the dual distribution mode of “high-high” and “low-low”.Therefore,this paper proposes some suggestions,such as improving the rural land transaction market,increasing investment in agricultural infrastructure,optimizing the elements of rural land investment,further deepening the reform of rural land resource allocation,and planning the strategies to improve the efficiency of rural land transaction in various regions according to local conditions.
