基于引力模型的长三角城市群电影经济格局研究

Research on the Spatial Pattern of the Yangtze River Delta Film Economy Based on Gravity Model

文化产业发展趋势表明,空间集聚和空间相互作用是其发展的重要特征之一。利用城市引力模型,对长三角城市群电影经济的空间联系结构和相互作用格局进行分析。结果表明:长三角城市群主要城市间的电影经济引力不断增强,且上升幅度较大;太湖平原和杭嘉湖平原的核心城市引力始终最强,特别是距离较近的上海与苏州;长三角城市群的城市电影经济联系呈现出发展不平衡、地理邻近区域联系较密切的特点;长三角地区电影经济的空间集中性较明显,呈现出“东强西弱、多极崛起”的特点。

The trend of cultural industry in recent years shows that spatial agglomeration and interaction have become a significant feature in this regard.Adopting gravity model,this paper is intended to analyze the spatial linkage structure and interaction pattern of the film economy in the Yangtze River Delta.The results show that the“gravity”(attractiveness)of film economy among cities in this area is ever increasing by a large margin;the“gravity”of core cities in the Taihu Plain and Hang-Jiaxing-Huzhou Plain is always the largest,especially between Shanghai and Suzhou,which are closer to this area;the film economy in the cities along the Yangtze River Delta features unbalanced development and a closer connection among the neighboring area;it also shows an obvious feature of geospatial agglomeration with“multi-polar growth”,“stronger in the east and weaker in the west”.
