In recent years,ports in China have increasingly become one of the ideal investment locations for international *** analysis of the relationship between foreign direct investment and market structure of ports in China has a certain reference value for the further study of the development of port market *** also helps to make proper port policies for our *** this paper,we take port group of the Pearl River Delta for instance,two independent variables,the whole amount of foreign direct investment and enterprises number,are selected in the regression model to test the relationship between FDI and market concentration,which is based on the calculating of related coefficient between *** is concluded that foreign direct investment promotes the concentration of port markets to some extent,aggravating port market monopoly.

Using fuzzy c-means clustering procedure to find a condensed set for Parzen windows estimation (Parzen FCMC ) is proposed in this *** full Parzen windows estimator usually requires more computation and ***,the experimental simulations show that the significant increase of reference data may not improve the estimation performance of Parzen windows method *** addition,the theoretical analysis validates the traditional Parzen windows estimator is sensitive to noise ***,in order to improve the generalization capability (i.e.,the adaptability to nosie data) of Parzen windows estimation,we try to find a condensed dataset to conduct the probability density estimation by adopting the following measures: 1) clustering the original dataset by using fuzzy c-means;2) estimating the underlying density function based on the condensed reference ***,the experimental results on the synthetic datasets obeying Uniform,Normal,Exponential,and Rayleigh distributions show the usefulness and effectiveness of proposed Parzen FCMC .The significant savings on computation and storage can be achieved with only minimal mean integrated squared error (MISE) degradation.
