基于经济联系对云南省与浙江省空间异质性比较及分析

Comparison and Analysis of Spatial Heterogeneity between Yunnan Province and Zhejiang Province Based on Economic Connection

摘要: 探讨城市间相互作用水平不仅有利于构建布局得当、结构有序、规模合理的城镇体系，而且对推动区域人口、资金等要素快速流动转化和实现区域经济均衡发展起到重要作用。本文通过计算云南省以及浙江省各地级市之间的空间经济联系强度，并辅助地理加权回归对云南省和浙江省各城市之间的空间相互作用水平进行研究，研究结果表明：浙江省形成了东北部和西南部两个经济发展差异明显的地区，经济联系空间格局也呈现出明显的东北–西南的地域分异。而与浙江省对比，云南省昆明市中心地位突出，高首位度特征显著；但城市之间的联系强度整体偏低、空间联系不够紧密。提出一些云南省城市间相互作用水平提高的优化举措，以期给云南省城镇化建设和经济发展提供建议。

Abstract: Discussing the level of interaction between cities is not only conducive to the construction of an urban system with proper layout, orderly structure, and reasonable scale, but also plays an im-portant role in promoting the rapid flow and transformation of regional population, capital and other factors and realizing the balanced development of regional economy. In this paper, by cal-culating the strength of spatial economic linkages between Yunnan Province and prefecture-level cities in Zhejiang Province, and assisting geographically weighted regression to study the level of spatial interaction between Yunnan Province and Zhejiang Province cities, the research results show that: Zhejiang Province has formed two regions with obvious differences in economic de-velopment in the northeast and southwest, the spatial pattern of economic connections also pre-sents a clear northeast-southwest regional differentiation. Compared with Zhejiang Province, the city center of Kunming in Yunnan Province has a prominent position and high primacy; however, the connection strength between cities is generally low and the spatial connection is not close enough. Some optimization measures to improve the level of interaction between cities in Yunnan Province are put forward, in order to provide suggestions for urbanization construction and eco-nomic development in Yunnan Province.
