长江中游城市群空间结构的经济绩效影响研究

近年来，城市群成为我国新型城镇化的空间主体，研究城市群空间结构具有重要意义。但现有文献大多从人口维度对城市群空间结构进行分析，缺乏多维视角，其结论的参考价值有限。本文以长江中游城市群为研究对象，运用2006-2015年长江中游城市群内部三大城市群的面板数据，通过位序规模法则以及空间基尼系数，从人口与产业两方面对城市群空间结构进行测度，并进一步研究了城市群空间结构对其经济绩效的影响。结果表明，在控制了其他影响因素之后，人口呈多中心分布，产业呈单中心分布对长江中游城市群的经济绩效有显著的促进作用；资本投入、基础设施建设、政府干预、产业结构和人口规模均是影响长江中游城市群经济绩效的关键因素。未来长江中游城市群可运用人口引导产业流动，以推进多中心的发展进程。

THE ECONOMIC PERFORMANCE OF URBAN CLUSTER SPATIAL STRUCTURE IN THE YANGTZE RIVER MIDDLE REACHES

In recent years, urban agglomeration has become the spatial subject of China's new urbanization, and it is of great significance to study the spatial structure of urban agglomeration. However, most existing literatures analyze the spatial structure of urban agglomeration from the perspective of population, which lacks multi-dimensional perspective and has limited reference value. Taking the middle reaches of the Yangtze River middle reaches urban agglomerations as the research object, this paper use the panel data of the Yangtze River middle reaches urban agglomerations from 2006 to 2015 to make an empirical study on the impact of urban agglomeration spatial structure on its economic performance from two aspects:population and industry. To achieve this goal, we use the rule of rank size and the Gini coefficient in space.Theresults show that polycentric spatial structure in population has significant positive influence on economic performance while the industry spatial agglomeration has a positive effect on the economic growth. The research also shows that capital input, infrastructure construction, government intervention, industrial structure and population size are the key factors affecting the economic performance of the Yangtze River middle reaches urban agglomerations.In the future, the Yangtze River middle reaches urban agglomerations can use population to guide industrial flow, so as to promote the multi-center development process.
