摘要
引入区域重心的概念、模型及计算方法,采用2002~2009年中国各省(市、区)体育用品制造业及分支行业的资产总计数据,推算出各年该行业重心的空间演变轨迹,并从重心移动距离、移动方向等角度阐述了此行业重心的动态变化及空间联系。结果表明:2002~2009年我国体育用品制造业及各分支行业重心均远偏离中国的几何中心(东经103.50°,北纬36°),且各重心向西和向南移动的频率较高。体育用品制造业及各分支行业重心在经纬度方向上的变化幅度和直线移动距离存在明显差异,其重心的累计实际移动距离、年均迁移距离与年际移动距离也都具有较显著的差异性。
By introducing the concept, model and calculation method of regional gravity and using the 2002 - 2009 data of China' s total assets of sporting goods industry and its branch industries, the paper calculates the spatial evolution track of the industry' s gravity of each year and illustrates the dynamic changes and spatial correlation of the industry ac cording to the movement distance and direction of the gravity. The results show that from 2002 to 2009, the gravity of China's sporting goods manufacturing industry and its branch industries deviated from the geometric center of China ( longitude 103.50°, latitude 36°) and the westward and southward gravity demonstrated much higher frequency. There exist significant differences between the changes in latitude and longitude of sporting goods manufacturing industry and the distance of straight - line movement, with the total actual movement distance, the average annual migration distance and the interannual distance also indicating significant differences.
