The Evolution Of Economic Spatial Structure In Pearl-river-delta City Region From2000to2010

In recent years, globalization has made a great influence on the urban systems of variouscountries and regions, and is changing the world political and economic situation greatly. Onone hand, the space economic structure has qualitatively changed from―industry chain‖characterized structure to―value chain‖characterized structure. On the other hand, in thenetwork era created by globalization and information technology, more and more regions andcountries have been brought into the global economic network, in the global network, formeda multi-polar, multi-level urban network system has come into being consequently. Denseurban area cored on the international metropolis has become the principal parts ofinternational competition.This study focuses on the causal mechanism of the industry restructuration and theevolution of economic spatial structure in PRD9cities brought by globalization.Conventional methods are adopted here. First, by constructing the index system ofglobalization, and analyzing these factors, especially the foreign direct investment and theevolution of international trade, the effect of globalization brought to the9cities is estimated,which shows us the level of―global value chain‖the cities stand at. Secondly, the evolution ofeconomic spatial structure is estimated by analyzing the industry structure evolution andnetwork associates in the9cities. Third, complex network analysis tools are used here tomeasure the complex network features of the Pearl River Delta urban areas, such as the nodedegree distribution, linkage direction and the nodal assortativity. At the last, the dynamicmechanism of the formation of polycentric pattern of economic spatial structure in urbanareas, and the features of globalization typical urban industrial clusters are both discussed inthe essay.
