随着经济增长与城市化进程的不断加快,建筑业在国民经济中发挥着日益重要的角色。在探析建筑业系统与区域经济系统耦合机理的理论基础上,借鉴物理学耦合度函数构建了建筑业与区域经济增长的耦合协调度模型,并使用我国2008年省级层面数据,对建筑业与区域经济增长的耦合协调发展状况进行了实证研究。结果发现,我国各省区建筑业与区域经济增长的耦合度均处于较高水平,耦合度最低的西藏自治区也达到0.9139;为了避免耦合度指标存在的缺陷而构建的耦合协调度指标则证实,我国各省区建筑业与区域经济增长耦合协调程度存在明显的空间差异,可分为良好协调、中级协调、初级协调和勉强协调四种类型,且大部分省区处于初级协调或勉强协调阶段。
With the accelerating economic growth and urbanization process, the construction industry is playing an increasingly important role in the national economy. Based on theoretical analysis of coupling mechanism between construction industry and regional economic system, the paper builds the coupling coordinative degree model of construction industry and regional economic growth drawing on physical coupling function, using provincial level data of China in 2008, and analyses empirically the coupling coordinative state of the construction industry and regional economic growth. It was found that the construction industry and regional economic growth of China's provinces are at a high level of coupling, with the coupling degree of the Tibet Autonomous Region being 0.9139.The coupling coordinative degree is built in order to avoid defects of coupling degree index, which confirms that the coupling coordinative degrees of provincial construction industry and economic growth have significant spatial differences, which can be divided into four types of good coordination, intermediate coordination, primary coordination and unconvincing coordination, and most of the provinces are in the initial stage of primary coordination or unconvincing coordination.
