重庆市产业结构与土地经济密度的关联协调研究

Research on the Association and Coordination Between Industrial Structure and Land Economic Density in Chongqing

基于1997—2016年的重庆市产业结构与土地经济密度面板数据,运用灰色关联分析和协调度模型分别探讨了产业结构与土地经济密度的相互作用和内在联系,以期为重庆市产业结构优化升级和土地节约集约利用提供决策参考。结果表明:(1)1997年以来,重庆市的产业结构处于不断优化的阶段,三次产业占比呈现出"三二一"的结构特征;(2)产业结构水平对土地经济密度的影响作用最为显著;(3)总体上产业结构与土地经济密度之间存在着失调─弱协调─协调的演化规律,并且土地经济密度变化要滞后于产业结构变化;(4)当产业结构与土地经济密度关联程度达到较高水平或上升趋势时,二者间协调度为正,相互促进。由此得出:重视产业结构水平提升在产业结构优化升级中的影响,并引导产业结构合理化和产业结构高级化有效推进,实现土地资源产出效益最大化和空间上的合理化配置。

Based on the industrial structure and land economic density data of Chongqing from 1997 to 2016,the interaction and internal relations between industrial structure and land economic density were discussed by using gray relational analysis model and coordination degree model,respectively,in order to provide some reference in the optimization of the industrial structure of Chongqing and the conservative and intensive use of land.The results showed that：（1）since 1997,the stage in the continuous optimization of the industrial structure of Chongqing City,three industries accounted for showing the structural characteristics of‘threetwo-one＇;（2）effect of the level of industrial structure influence on land economic density was the most significant;（3）there is an evolution of weak coordination disorder between the industrial structure and land economic density,and the change of land economic density lagged behind the change of industrial structure;（4）when the correlation between industrial structure and land economic density was at a high level or an upward trend,the coordination degree of the two was positive and mutually promoted.In the industrial structure optimization and upgrading,the government should emphasize the level of industrial structure,at the same time,should effectively promote the rationalization and up-gradation of industrial structure,in order to achieve rational allocation of land resources and the maximization of output efficiency.
