滇中城市群产业结构与用地结构关联研究

Study on Relationship between Industrial and Land Structure of Yunnan Central Urban Agglomeration Area

城市群产业结构与用地结构的协调发展有利于提高滇中城市群用地的空间绩效,优化城市群产业结构,提升城市群的整体功能。运用比例变化指数和Granger因果关系方法研究了滇中城市群产业结构和土地利用之间的变化关系:滇中城市群产业结构变化滞后于城市土地结构变化,城市土地结构变化和产业结构变化的差距呈先增加后减少的趋势,即滇中城市群产业结构和土地利用结构由非同步变化逐渐进入同步变化轨迹;短期内,滇中城市群产业结构变化促进了优化土地利用,土地利用变化又反作用于产业结构,但滇中产业结构和用地结构未出现同步变化规律,说明滇中产业结构和土地的因果关系结构要在长期发展才可能实现。

The coupling relationship between industrial and land structures of Yunnan Central Urban Agglomeration Area was important for increasing land use benefit, optimizing industry structure and advancing urban function. This paper used proportion change index and Granger method to discuss the relationship between industrial and land structures of Yunnan Central Urban Agglomeratios Area. The conclusions showed that industry structure change lagged behind urban land use change, the difference took on ascend- descend trend. In short - term, urban land use change drove industry structure, then industry structure fed back urban land use structure. The coupling relationship between urban land use structure and industry structure didn＇t appear in the long time harmony, it would come true.
