中国民族乐器制造企业的空间格局

Spatial Pattern of National Musical Instrument Manufacturing Enterprises in China

运用探索性空间数据分析、最邻近指数以及核密度等分析方法,并基于点与面2个方面对中国民族乐器制造企业的空间格局特征进行分析,结果表明:基于点的方面,中国民族乐器企业及其分类别的民族乐器企业的空间分布均呈显著集聚状态,且集聚度较高,其中吹奏乐器企业集聚度最低,而长三角、珠三角、环渤海地区以及滇、豫等区域是其重要的集聚区;基于面的方面,中国民族乐器企业及其分类别民族乐器制造企业分布均呈弱集聚状态;其热点区数量均很少,且分布与基于点的集聚区分析结果基本一致,而全国绝大部分的城市为冷点区域。中国民族乐器制造企业空间格局的影响因素可归纳为资源禀赋、历史基础以及集聚经济效应3个方面。

In order to make a quantitative analysis on spatial pattern of national musical instrument manufacturing enterprises in China, Arc GIS 9.2 and the related technology of exploratory spatial data analysis, the nearest neighbor index and the nuclear density index are applied in this paper based on spatial pattern of point and region. The results show that：1） As for the point aspect, the distribution of musical instrument manufacturing enterprises as a whole and different types of the instrument manufacturing enterprises in China presents a spatially congregated pattern significantly. In terms of the degree of the agglomeration of the national instrument manufacturing enterprises, the overall degree of agglomeration is quite high, while that of the wind instruments the lowest. The Yangtze Delta Region, the Bohai Sea rim, the Pearl River Delta region, Yunnan and Henan are important agglomeration regions. 2） As for the region aspect, the spatial pattern of all the national instrument manufacturing enterprises and different types of the enterprises in China is characterized by weak concentration. The number of hotspot regions is quite small, and their distribution is consistent with the results in the point agglomeration analysis above. However, the majority of the cities in China belong to coldspot regions. And specifically,the hotspot regions of national instrument manufacturing enterprises in China concentrate in three cities, which are Yangzhou, Hangzhou and Kunming, and Yangzhou is the only hotspot region of plucked string instruments manufacturing, while Hangzhou and Kunming are the hotspot regions of wind instruments manufacturing. Besides, the hotspot regions of percussion instrument are in two cities, which are Langfang and Luoyang. The number of hotspot regions of stringed instruments manufacturing is large by contrast, which include eight cities, they are Beijing, Tianjin, Cangzhou, Hengshui, Linyi, Suzhou, Wuxi and Yangzhou. On the basis of the above results, the factors that impact the spatial pattern of national instrument manufacturing enterprises in China could be summed up as three aspects： resource endowment, historical basis and agglomerative economy effect.
