辽宁沿海地区海洋经济增长质量空间特征及影响要素

在海洋经济质量转型之期,基于“认知—评价—建构—优化”理念,界定海洋经济增长质量内涵,通过中心-引力模型评价分析2000—2014年辽宁沿海地区海洋经济增长质量空间特征,构建了海洋经济增长质量模型,识别影响其空间特征的相关要素,并根据要素作用程度提出优化建议。研究发现：① 辽宁沿海地区海洋经济增长质量呈“核心—圈层”结构,形成以大连为“领头雁”的雁阵式相互继起模式;“钻石型”引力流结构促成辽宁沿海地区集中化连片发展格局;② 海洋经济增长质量空间特征主要受空间集聚效应影响,海洋资本、海洋基建和海洋产业结构成为推动海洋经济增长质量循环引力流的顺流机制,其中海洋产业结构成为影响辽宁海洋经济增长质量圈层空间集聚效应的关键流;海洋人才成为制约海洋经济增长质量循环引力流的逆流机制;③ 通过路径作用程度的象限划分,提出强化大连中心地职能,针对腹地城市定位及资源禀赋条件提出调控措施,推进沿海区域协调与一体化进程。

Spatial characteristics and influencing factors of marine economic growth quality in Liaoning coastal areas

Under the new normal background, marine economy in China should develop with higher quality and effectiveness. Based on the framework of "knowldege/understanding-evaluation-construction-optimization", this study defined the connotation of marine economic growth quality and used a center-gravity model to analyze the spatial structure of marine economic growth quality in Liaoning coastal areas from 2000 to 2014. A spatial econometric model was used to examine the spatial effects and influencing mechanisms for marine economic growth. Recommendations for path control were proposed according to the extent of factor effects. The study found that: 1) Marine economic growth quality in Liaoning coastal areas exhibits a "core-circles" structure, forming a goose-straddle pattern with Dalian as the leading goose. A diamond-shaped gravitational flow promotes the concentrated development for the area. 2) There is a significant spatial agglomeration effect in the gravitational flow of marine economic growth quality in Liaoning coastal areas. The results of the spatial Durbin model show that the elements of marine capital, marine infrastructure, and marine industrial structure have become downstream mechanisms that promote marine economic growth quality in the area, and marine industrial structure is the main flow for marine economic growth quality, which has obvious influence in spatial agglomeration. However, marine talents have become a constraint flow on marine economic growth quality in Liaoning coastal areas, which restricts the flow of relevant elements. 3) Through the division of path effects, we proposed to strengthen the role of Dalian as the central area, formulate control measures for cities in the hinterland based on their roles and resource endowments in the regional system, and promote the process of coordination and integration in Liaoning coastal areas.
