Empirical analysis on impact of FDI on the level of urbanization in costal areas
Purpose: There is a close relationship between FDI and the level of urbanization. the
objective of this research is to analyze the relationship between FDI and the level of
urbanization in Jiangsu and Guangdong provinces in costal areas.
Design/methodology/approach: The author uses the modern econometric methods by
panel unit root test, cointegration test, random effects models and fixed effects models, and the
data of FDI (2000-2012), urbanization rate, industrial structure and regional GDP of Nanjing,
Xuzhou, Suzhou, Wuxi and other 13 cities in Jiangsu Province, Guangzhou, Shenzhen and
other 19 cities in Guangdong province, researches the relationship between FDI and
urbanization rate.
Findings: Models show, FDI was closely correlated with urbanization rate in Jiangsu province
and Guangdong province, the highly correlated with industrial structure, while it negatively
correlated with the growth of GDP, and the degree of correlation is not high in Jiangsu
province, but the high negative correlation in Guangdong province. The results shows the
industrial structure and the urbanization rate mainly cause FDI growth.
Research limitations/implications: There are many provinces in costal areas of China, this
paper just research the relationship between FDI and the level of urbanization in Jiangsu
province and Guangdong province, there are some limitations in the study areas and results.Peer Reviewe
Correlations in interference and diffraction
Quantum formalism of Fraunhofer diffraction is obtained. The state of the
diffraction optical field is connected with the state of the incident optical
field by a diffraction factor. Based on this formalism, correlations of the
diffraction modes are calculated with different kinds of incident optical
fields. Influence of correlations of the incident modes on the diffraction
pattern is analyzed and an explanation of the ''ghost'' diffraction is
proposed.Comment: 16 pages, 2 figures, Latex, to appear in J. Mod. Op
