基于经济视角的乡村“人、地、业”转型耦合协调性差异研究——以重庆市渝北区两镇为例

Coupling and Coordinationof Rural“People,Land and Industry”Transformationfrom the Perspective of Economic Gradient——A Case Study of Two Towns in Yubei District of Chongqing

从经济水平差异角度探索乡村“人、地、业”3要素转型的耦合协调性.构建“人、地、业”转型评价指标体系,运用耦合协调度模型测算重庆市渝北区两镇2010年、2013年和2017年的“人、地、业”转型及其两两间的耦合度、耦合协调度.结果显示:①经济水平与耦合度呈正相关,经济水平越高的地区乡村“人、地、业”转型耦合度越呈高水平阶段波动且幅度较大,反之则越小;耦合协调度与耦合度存在一致性,经济水平高的区域耦合协调度高,并且呈现出由低到高的有序增长演进趋势;经济水平低的区域耦合协调度低,呈现由低到高跨越式波动的演进特征.②从整体可以发现,人口—产业转型耦合度高于人口—土地利用、土地利用—产业耦合水平,并且经济水平高的区域人口—产业、土地利用—产业转型耦合度演进过程更为有序;人口—土地利用转型耦合度波动大,而经济水平低的区域则与之相反.明确乡村所处的发展阶段,合理配置有限的乡村资源,扶植乡村产业发展是实现乡村协调发展的关键.

The coupling and coordination of rural"people,land and industry"transformation are studiedfrom the perspective of economic gradient.First,anevaluation index system of"people,land and industry"transformation is constructed.Then,the coupling and coordinating degree modelis used to calculate"people,land and industry"transformation in two towns in Yubei District of Chongqing in 2010,2013 and 2017 and the coupling and coordinating degreesbetween the three elements.The results show that the higher the level of economic development,the larger the fluctuation of rural"people,land and industry"transformation coupling degree is in the high-level stage,and the smaller the fluctuation is in the low-level stage;the degree of coordinating and the degree of coupling are associated,the regions with higher economic development havehigher degree of coupling coordinating and the evolution process is more stable.In contrast,the regions with lower economic development have lower degree of coupling coordinating.and the evolution process shows a dramatic improvement from thelow level to thehigh level.The regions with high-level economic development havehigh coupling degree of population-industry transformationandhigh stability of evolution stage and evolution process,the evolution process of their land use-industry transformation coupling degree is more orderly,and the coupling degree of population-land use transformation fluctuates greatly,whereas the regions with low level of economic development exhibit an opposite picture.The authors point out at the end of the paper that in order toachieve a coordinated development of rural areas,it is essentialto clarify the development stage of the rural area,rationally allocate itslimited resources and support the development of rural industry.
