运用重心分析方法考察了中国公路货物运输与制造业重心的空间分布和变化特征,探讨了二者间的相互关系。研究发现:我国公路货物运输重心表现为缓慢的南下东进特征,移动距离由剧烈走向缓和;与几何重心比较,公路货物运输和制造业空间分布一直处于不均衡状态,公路货物运输发展水平与制造业发展水平的区域差异总体上在扩大;与我国制造业重心变化轨迹相比,公路货物运输重心变化轨迹相似度较高,但公路货物运输重心变化具有先导性,且先导性程度日趋减弱,说明公路交通发展对制造业空间布局发展具有重要的影响作用,但随着公路交通的进一步发展,其引领与拉动作用逐渐减弱;公路货物运输和制造业区域差异受国家空间经济产业布局政策及由其导致的开放程度、开放时序的差别影响较大。 Using the method of center of gravity analysis, the spatial distribution and change characteristics of the center of gravity of China’s road freight transport and manufacturing are investigated, and the interrelationship between the two is explored. The research shows that: the center of gravity of highway freight transportation in our country shows the characteristics of slow southward eastward movement and the moving distance from intense to moderate; compared with the geometric center of gravity, the spatial distribution of highway freight transportation and manufacturing has been in an unbalanced state; the development and manufacture of highway freight transportation As a whole, the regional differences in the level of industrial development are expanding. Compared with the trajectory of manufacturing center of gravity in our country, the trajectories of the center of gravity of highway freight transportation have high similarity. However, the changes in the center of gravity of highway freight transportation are leading and the degree of leading declines gradually, The development of highway traffic has an important influence on the spatial distribution of manufacturing industry. However, with the further development of highway traffic, its leading and pulling role is gradually weakened. The regional differences of highway freight transportation and manufacturing industry are affected by the national spatial economic industrial layout policy and by The degree of openness and opening up caused by the difference has a great impact.
