长株潭城市群产业协同度测度及影响因素研究

城市群是城市化发展到高度水平的产物，在城市群发展过程中，产业结构发展状态直接关系到城市群的可持续发展。长株潭城市群于1997年正式开始规划建设，发展至今，三市在融合发展上取得了较好的成效，但也存在着产业结构相似导致区域内部竞争、行政区域划分弱化合作机制、传统产业比重过大而高新技术产业发展较慢等问题。针对这些问题，利用熵权法计算长株潭城市群和长株潭三市三次产业发展的有序度，并建立复合系统模型计算长株潭城市群和长株潭三市的产业协同度，再利用随机效应模型分析长株潭城市群产业协同度的影响因素。结合产业协同发展的影响因素，提出加强产业结构规划、加强合作机制建设、完善市场资源配置等建议，以不断优化长株潭城市群产业协同。

Study on the Industrial Synergy Degree Measurement of Changsha-Zhuzhou-Xiangtan City Cluster and its Influencing Factors

Urban agglomeration is a product of the high level of urbanization. In the process of urban agglomeration development, the state of industrial development is directly related to the development of urban agglomeration. The planning and construction of Changsha-Zhuzhou-Xiangtan city cluster was officially initiated in 1997. So far, the three cities have achieved good results in the integration development, but there are also some problems such as similar industrial structure leading to regional internal competition, weakening cooperation mechanism in the division of administrative regions, too large proportion of traditional industries and slow development of high-tech industries. In response to these problems, using entropy weight method to calculate the order degree of the three industrial development of Changsha-Zhuzhou-Xiangtan city cluster and that of the three cities respectively, and establish a composite system model to calculate the industrial coordination degree of these three cities, then the random effect model is adopted to analyze the influencing factors of the industrial synergy of Changsha-Zhuzhou-Xiangtan city cluster. In combination with the influencing factors of industrial coordinated development, this paper puts forward policy suggestions to strengthen industrial structure planning, strengthen cooperation mechanism construction and improve market resource allocation, continuously optimizing the industrial coordination of Changsha-Zhuzhou-Xiangtan urban agglomeration.
