产业结构优化与土地集约利用耦合协调研究——以四川省为例

Coupling of Industrial Structure Optimization and Land Intensive Use and Its Coordinated Development——A Case Study of Sichuan Province

测度产业结构的优化调整与土地集约利用度间的耦合协调性,能够为促进产业分区集聚、高质量发展提供有科学性和针对性的决策与指导.采用四川省21个地级行政区2007,2012和2017年指标数据,在测度各地区产业结构与土地集约利用水平基础上,借助耦合协调度模型研究二者的耦合协调关系并进行分区优化.①四川省产业结构优化与土地集约利用水平呈平稳上升态势但区域差异明显,东部明显优于西部;②两系统间以中、低度耦合协调为主,时间序列上表现为提升趋势,空间上形成以绵(阳)—成(都)—攀(枝花)为界,“东高西低”的分异格局;③产业发展分区优化策略可分为I类辐射带动式、II类优质提升式、III类产业转型式和IV类绿色产业式4种类型.基于产业结构优化与土地集约利用间的正向交互作用,结合区域差异,采取不同的产业发展策略,是实现产业与土地优质协调发展的有效途径.

The scientificity and pertinency of industrial clustering and high-quality development are described by coupling and coordinating degree between industrial structure optimization and land intensive use.The paper deals with the coupling relationship and partition optimization results between industrial optimization and land intensive use with the date of 21 prefectural-level division of Sichuan Province in the years of 2007,2012 and 2017,and based on the analysis of industrial structure characteristics and land intensive using level.The results show that,①The level of industrial structure optimization and land intensive use show a steady upward trend,but the regional difference is obvious,which the east area is higher significantly than the western region.②The coupling coordination relation of the industrial structure optimization and land intensive use are mainly in medium-low degree,it show an upward trend in the time series and“high in the east and low in the west”in the spatial pattern,which takes the Mian(yang)-Cheng(du)-Pan(zhihua)as the boundary.③The industrial zoning development strategy can be divided into four types:type I area adopts the radiation driving strategy;type II area adopts the quality improvement strategy;type III area should adopt the industrial transformation strategy;and type IV area should adopt green industry development strategy.Based on the positive interaction between industrial structure optimization and land intensive use,and different industrial development strategies are adopted which combination with regional differences,it is an effective way to achieve coordinated development between industry and land.
