区域高质量发展的空间联系及辐射效应研究——以辽宁沿海经济带为例

Spatial connection and radiation effect of regional high-quality development:A case study of the Liaoning coastal economic belt

推动辽宁沿海经济带高质量发展,对促进辽宁发展、东北振兴、东北亚区域合作均具有重要意义。在梳理高质量发展内涵的基础上,论文构建高质量发展评价指标体系,运用熵权TOPSIS法测度2006—2020年辽宁沿海经济带高质量发展水平;利用改进引力模型探讨高质量发展的空间联系结构及引力格局,结合威尔逊模型对城市高质量辐射范围测算。结果表明:(1)研究期内辽宁沿海经济带高质量发展水平呈波动上升趋势,发展水平空间差异显著,同时呈现“以大连为高地,黄海翼、渤海翼两大低谷连绵区”的空间分布格局。(2)各维度指标发展动力主要来源于协调发展、深化改革和绿色发展;创新发展、动能转换和共享发展呈大连一核引领的空间分异,绿色发展和协调发展呈渤海翼领先发展的空间分异,开放发展和深化改革呈黄海翼领先发展空间分异特征。(3)空间联系网络结构复杂,但仍需进一步创新辽宁沿海经济带、沈阳经济区、辽西北三大区域协调发展机制,提升城市空间联系等级。(4)辽宁沿海经济带呈现出对外辐射型、对外依赖型、辐射依赖相当型3类城市空间联系结构;并将经济带划分为“一核引领、两翼协同、多点支撑”的引力格局;大连是唯一的对外辐射型城市,空间辐射范围也呈对外扩张趋势。

Promoting the high-quality development of the Liaoning coastal economic belt is of great significance for the development of Liaoning Province,the revitalization of Northeast China,and the regional cooperation in Northeast Asia.On the basis of clarifying the connotation of high-quality development,this study constructed an evaluation indicator system of high-quality development,and used the entropy weight TOPSIS method to measure the high-quality development level of the Liaoning coastal economic belt from 2006 to 2020.Furthermore,using the improved gravity model,this study explored the spatial connection structure of highquality development and the division method of gravity pattern,and combined the Wilson model to measure the radiation range of cities with radiation capacity.The results show that:1)During the study period,the highquality development level of the Liaoning coastal economic belt showed a slightly fluctuating upward trend,and the spatial difference of development level was significant.2)The driving factors of the development of each dimension were coordinated development,deepening of reform,and green development.Innovation development,kinetic energy conversion,and shared development showed a spatial differentiation led by Dalian City;green development and coordinated development showed a spatial differentiation of leading development in the Bohai Wing;and opening-up and deepening reform showed a spatial differentiation of leading development in the Yellow Sea Wing.3)The complexity of the spatial connection network structure is increasing year by year,but it is still necessary to further innovate the coordinated and interactive development mechanism of the three major regions of Liaoning coastal economic belt,Shenyang economic zone,and Northwest Liaoning,to improve the level of urban spatial connection.4)The Liaoning coastal economic belt presents three types of urban spatial connection structure:external radiation type,external dependence type,and balanced radiation and dependence type.Dalian is the only external radiation city,and the spatial radiation range also shows an outward expansion trend.
