| 摘要: |
| 为探究辽中南-哈长城市群生产功能、生活功能以及生态功能(简称“三生”功能)耦合协调时空演化规律，从农业生产、非农业生产、经济发展、空间承载、生活水平、公共服务、生态压力、生态维持以及环境净化9个方面选取30项指标测算“三生”功能，并结合修正后的耦合协调模型与灰色关联度模型分析2000—2020年城市群“三生”功能耦合协调时空分异规律及影响因素。结果表明:1)辽中南-哈长城市群“三生”功能整体提升，哈长城市群仅生态功能发展优于辽中南城市群。其中:生产功能、生活功能、综合功能高值区主要为沈阳、大连等核心或沿海城市；生态功能高值区主要为牡丹江、吉林等内陆或沿边城市。此外，2015年以后“三生”功能优势区扩张趋于减缓甚至停滞，部分城市生产功能与生活功能明显降低，并且城市群交汇处“三生”功能整体持续偏低。2)城市群“三生”功能耦合协调性逐渐提升，辽中南城市群协调性整体优于哈长城市群。核心城市“三生”功能协调性主要为中级协调，非核心城市由轻度失调转为基本协调为主；轻度失调型城市空间分布由南向北转移，最终围绕哈尔滨和长春两大核心城市分布。3)对本研究所选取的9项影响指标测算结果表明，城市群“三生”功能耦合协调时空差异前三大影响因素为绿色全要素生产率、财政分权、年均降雨量。综上，本研究结果可为新时期的东北地区“三生”功能协调优化提供科学依据。 |

| Abstract: |
| In order to explore the spatial and temporal evolution law of coupling and coordination of “production-living-ecological” functions in the central-southern Liaoning and Harbin-Changchun urban agglomerations, a total of 30 indicators were selected from 9 aspects of agricultural production, non-agricultural production, economic development, space carrying, living standard, public service, ecological pressure, ecological maintenance and environmental purification to calculate “production-living-ecological” functions. The revised coupling coordination model and the grey relational model were combined to analyze the temporal and spatial differentiation and influencing factors of the “production-living-ecological” functional coupling coordination in urban agglomerations from 2000 to 2020. The results show that: 1)The “production-living-ecological” functions of the central-southern Liaoning and Harbin-Changchun urban agglomerations are improved as a whole, and only the development of ecological function of Harbin-Changchun urban agglomeration is better than that of the central-southern Liaoning urban agglomeration. Among them, high-value areas with production, living and comprehensive functions are mainly the core or coastal cities such as Shenyang and Dalian; The areas with high ecological function are mainly inland or border cities such as Mudanjiang and Jilin. In addition, after 2015, the expansion of “production-living-ecological” functions advantage areas tend to slow down or even stagnate, the production function and living function of some cities are significantly reduced, and the “production-living-ecological” function at the intersection of urban agglomerations continues to be low. 2)The coupling and coordination of "production-living-ecological" functions of urban agglomeration has gradually improved, the coordination of the central-southern Liaoning urban agglomeration is better than that of the Harbin-Changchun urban agglomeration. The coordination degree of the “production-living-ecological” functions of the core cities were mainly intermediate, non-core cities have changed from mildly maladjustment to general coordination. The spatial distribution of mildly imbalanced cities transfer from south to north, and finally distributes around the two core cities of Harbin and Changchun. 3)The calculation results of the nine impact indicators selected in this study show that: the top three influencing factors of the spatial and temporal differences in the coupling and coordination of “production-living-ecological” functions of urban agglomerations include the green total factor productivity, fiscal decentralization and average annual rainfall. In summary, this study can provide scientific basis for the coordinated optimization of “production-living-ecological” functions in Northeast China in the new era. |
