| 摘 要： 通过产出密度函数构建数理模型，基于黄河流域60个地级市2008—2018年的面板数据，利用两步差分GMM方法和动态面板空间杜宾模型，探究经济集聚对经济环境协同水平、经济高质量增长以及生态保护的影响。结果表明：经济集聚对经济环境协同发展的影响呈倒U型，拐点值为1.91，目前黄河流域经济集聚水平远低于拐点值，经济集聚还存在较大上升空间；经济集聚水平存在一个最优区间，在这个区间内，经济集聚既能促进经济高质量增长和生态保护，又有利于两者的协同发展，但目前黄河流域的经济集聚水平还未处于此区间内；经济集聚还存在显著的空间溢出效应，本地区的经济集聚会阻碍其他区域经济环境协同水平的提高，阻碍周围区域的经济高质量增长，但有利于其他地区的生态保护，邻近区域经济环境协同发展会促进本区域协同水平的提高。需要注意的是，在经济集聚过程中，区域中心城市存在着虹吸效应。在未来的发展中，黄河流域要不断提高经济集聚水平，畅通经济集聚的作用路径，实现经济高质量增长与生态保护的协同发展。 |

| Abstract: This article constructs a mathematical model through the output density function, and, based on the panel data of 60 prefecture-level cities in the Yellow River Basin from 2008 to 2018, uses the two-step differential GMM method and the dynamic panel space Dubin model to explore the impact of economic agglomeration on the economic environment, high-quality growth and ecological protection. The results show that the impact of economic agglomeration on the coordinated development of the economic environment is in an inverted U shape, with an inflection point value of 1.91. The current level of economic agglomeration in the Yellow River Basin is far below the inflection point, and there is still a large room for growth in economic agglomeration. There may be an optimal range for economic agglomeration, which can not only promote high-quality economic growth and ecological protection, but also benefit the coordinated development of the two, but the Yellow River Basin is not currently within this range. Economic agglomeration also has significant spatial spillover effects. Economic gatherings in this region hinder the improvement of the economic environment coordination level of other regions and the high-quality economic growth of the surrounding regions, but it is conducive to the ecological protection of other regions. The coordinated development of the economic environment of neighboring regions will promote the improvement of the level of coordination in the region. It should be noted that in the process of economic agglomeration, there is a siphon effect in regional central cities. In the future development, the Yellow River Basin must continuously improve the level of economic agglomeration, smooth the path of economic agglomeration, and realize the coordinated development of high-quality economic growth and ecological protection. |
