Abstract:

Globalization is not a one-way and homogeneous process, but the state of multi-dimension and the co-exist development in integration and fragmentation. Along with the global flow of capital, the global expansion of multinational corporations and the formation of world production network, globalization has become an important driving force to promote and shape the development of urban areas. However, the current study of urban regions more focuses on the function and nature of large cities, less mentions the spatio-temporal intra-regional transformation of globalization process, in the meantime, indicators involved in the study mainly concentrate in more urban economic function and less composite indicators. With the development of the integration of the world economy, urban regions, taking metropolitan area as the core region, is increasingly becoming a basic spatial unit of global competition, the spatio-temporal evolution and spatial disparity of globalization process of the specific space is particularly important. Over the past decades, the globalization development of some cities in China has made rapid development, more and more world urban researchers have become increasingly concerned about the globalization development of cities and regions in China and other developing countries. At the same time, as the country's largest urban agglomerations, the Changjiang River Delta is in a position of the forefront of China's participation in economic globalization, and is more sensitive and directly affected by the impact of external economy. In the light of above studies, regarding the Changjiang River Delta as the research object, including Jiangsu, Zhejiang and Shanghai, for a total of 25 prefecture-level cities, the article builds the index system from 4 aspects of economic contact, personnel flow, information communication and government cooperation, considering existing studies on the globalization index, combined with the concept of world cities and global cities, as well as the stage of global development in the Changjiang River Delta. Based on the index system above, the article assesses the spatio-temporal differences and dependence between different cities and spatial autocorrelation characteristics of globalization process of the Changjiang River Delta, and more importantly, spatio-temporal evolution characteristics of the different indicators are analyzed in detail. The results show that subject to the positive impact of accession to the WTO in 2001 and Shanghai World Expo held successfully in 2010, the negative impact of SARS in 2003 and the financial crisis in 2008, the globalization of the Changjiang River Delta expresses the characteristics of different stages. From the time series from 2000 to 2009, the performance of the globalization process showed accelerated increasing, steady rising and downward trend, but the different indicators showed different characteristics. From the spatial pattern, the globalization of the Changjiang River Delta gradually tend to be a balanced development of more reasonable from more concentrated state, backward regions develop quickly, and urban system is more reasonable under the influence of globalization. Using analytical methods of ESDA and Getis-Ord G_i*, the findings are that, the globalization process of the inter-county exhibits a strong dependence on the spatial concentration. Meanwhile, it is found that market and administrative jointly promote the process of globalization.
