摘要:

在构建城市间经济联系网络基础上,从网络密度、中心性、核心-边缘结构、QAP分析等角度对1988~2012年长江经济带经济网络结构演变及其驱动机制进行深入分析。结果表明:长江经济带经济联系网络结构日趋成熟,三大经济地带内城市内聚性显著增强但地带间差异逐渐缩小,经济网络向均衡化发展;城市度中心性整体持续下降,经济网络出现多核心趋势,城市介中心性高值区的梯度推移特征明显;“核心-边缘”结构分析显示核心度高值区呈片状格局,高核心度城市由“质大量少”向“质小量多”转变,经济网络的“核心-边缘”结构呈组团式发展,组团内形成各自核心城市;QAP分析显示经济全球化、要素集聚与扩散、产业升级、交通技术创新与城市群建设等机制共同驱动着长江经济带经济联系网络的演变及优化重组。

Abstract:

The Changjiang River Economic Zone is the second largest economy belt, followed Chinese coastal economic regions, which has the most competitive and the great development potential. The development of Changjiang River Economic Zone plays the important exemplary role and is strategically significant for regional harmonious development, new urbanization construction and ecological civilization construction in China. The analysis on the economic network evolution of the Changjiang River Economic Zone can effectively grasp the stage of regional development and make up urban and regional developmental strategy. With the aid of UCINET and ArcGIS, this article analyzed the evolution of economic network and its driving mechanism from density, centralization, “core-edge” structure and QAP (Quadratic Assignment Procedure) analysis based on economic construction data of city during 1988-2012. The result shows that: economic contacts’ network structure tends to be mature, cities’ inner cohesion enhances in three sub-zones, difference continues to narrow between sub-zones, and economic network develops to be balanced gradually. Network degree continues to decline, shows the tendency of many cores and forms the spatial pattern which contains three "highland", one "highland interlocking region" and one "low interlocking region". The areas with high value of betweeness centrality have an obvious grade feature which experiences three phases: equilibrium, non-equilibrium and relative balance. The core-edge analysis shows that the difference of cities’ individual core-degree tends to decrease and the zone shapes plate pattern with high core-degree. The city with high core-degree has a change from “Big size but little” to “Small size but more”. The “core-edge” structure of economic network was divided into many blocks which include the middle-lower reaches and the upper reaches of the Changjiang River. There has many core-cities formed in each block and the number of isolated cities rapidly reduces in the economic network. Economic ties remain to be strengthened between the two blocks. The economic network characteristic is roughly consistent with the situation of economy development pattern in the Changjiang River Economic Zone. The QAP (Quadratic Assignment Procedure) analysis shows that many factors drove economic network to evolve and optimize which contains transportation way’s innovation, economic elements agglomeration and diffusion and construction of urban agglomeration, economic globalization, etc.

Key words: modified gravitation model, social network analysis (SNA), economic network structure, the Changjiang River Economic Zone
