中文摘要：

制造业作为现代经济活动中最为重要的行业之一,随着发展方式转型升级及结构调整优化呈现出空间分布格局的变化。这种变化特征一方面能够反映其布局的客观规律和发展态势,另外也能从一个侧面刻画出区域的协同发展状况。京津冀区域制造业在区县层面上总体呈现出由中心区域的京津走廊向东部沿海及冀中南腹地扩散的特征,由于各行业要素属性的差异,导致各类型行业的空间格局变动情况各有不同,首先劳动密集型制造业呈现出由中心区域及核心区县向河北全域欠发达地区扩散的特征,资本密集型行业呈现出向东部沿海及冀南区域扩散的特征,而技术密集型行业则呈现出向环京津及冀中南重要城市扩散的特征。影响制造业空间格局变动最重要的因素主要包括要素禀赋、集聚动力以及区域政策。为优化京津冀制造业空间格局,应加快落实区域性产业政策,加快重要节点城市的交通基础设施建设,进一步推进区域产业合作及产业链延伸,促进区域制造业空间格局的多极化发展。

英文摘要：

The manufacturing industry is a very important part in modern economy. The upgrading of the modes of development and readjustment of industrial structure have prompted changes in manufacturing industry＇s geographical distribution. These changes, on the one hand, show the objective rule of manufacturing industry＇s geographical distribution and trend of development, and, on the other hand, reflect from a different perspective the region＇s coordinated development. On the level of municipal districts, the distribution of manufacturing industry in Jing-Jin-Ji Region features a radiating pattern that begins from the corridor between Beijing and Tianjin and reaches into the coastal areas in the east and into the middle and south of the inland in Hebei. Because of the variations in the factors of different industries, the changes of different industries＇ geographical distribution can be different. Labor- intensive manufacturing industry begins to diffuse from central regions or counties towards less developed areas in Hebei, capital-intensive manufacturing industry begins to spread into the coastal regions and the south of Hebei, and technology-intensive manufacturing industry begins to spread in areas surrounding Beijing and Tianjin and into important cities in the middle and south of Hebei. The most important factors that may influence the changes in the geographical distribution of manufacturing industry include regional endowments, gathering momentum and regional policies. In order to optimize the geographical distribution of manufacturing industry in Jing-Jin-Ji Region, the region should speed up its implementation of regional industrial policies, increase the speed of the construction of transportation infrastructure, promote regional industrial cooperation and extend the industrial chain, and propel the multi-polar development of manufacturing industry＇s geographical distribution in the region.
