摘要
通过构建耦合系统评价指标体系,运用灰色关联技术,对我国人口结构和经济结构的关联度、耦合度和时空演变特征进行测度分析,揭示了两大系统的耦合机理.研究表明:①人口结构与经济结构耦合性强,各要素存在交互影响,但彼此关联强度不等;②中国区域人口结构与经济结构耦合度空间分异明显,呈现出中部高、东西低的弱倒"U"型分布规律.根据区域产业结构特征和耦合度大小,大致将全国31个省区划分为低水平耦合、拮抗、磨合和协调四种类型,其中以拮抗和磨合类型为主;③中国人口结构与经济结构的耦合度在时序上总体表现出递减性趋势.
Through building an evaluation index system and using gray relational technology, the associate degree, coupling and the temporal and spatial evolution of China＇s population and economic structures are studied and mechanism of the coupling of the two systems are revealed. The results show that the coupling effect of the population structure and the economic structure is strong, and interaction exists among various elements, but the strength of relevance is different from each other. The spatial difference of regional population structure and economic structure＇s coupling degree is conspicuous in China, with a weakly inverted ＂U＂-shaped distribution in space. According to the characteristics of regional industrial structure and the degree of coupling, China＇s 31 provinces can be divided into four types, i.e. low-level coupling, confliction, amelioration and harmony, the amelioration and confliction types being dominant. From the time perspective, a diminishing trend exists in the coupling degree of population structure and economic structure in China.
