Empirical Analysis of Indirect Impact Factors on Price-Earning Ratio in Chinese Stock Market XU Ming, RONG Cheng-fa 2003, (4):  10-14.  Abstract ( 2084 )   PDF (859KB) ( 2590 )   Save Due to the special structure for equity ownership of Chinese listed companies,the price-earning ratio(PER)is distorted which consequently leads to an untrue reflection of the fluctuation of macroeconomics.This paper empirically analyzes the influence of non-circulating equity ownership,financial deepening structure and commodity price index on PER.The results show that in order to avoid a great impact on the stock market from the fact that the reduction of state-owned shares,the administration has to thoroughly adjust the financial deepening structure,improve the quality of listed companies and reform the related policy and system for the Chinese stock market.

Uncertainty Support Vector Classification for Early-Warning LIU Guang-li, ZHANG Ai-li, DENG Nai-yang 2003, (4):  58-61.  Abstract ( 2002 )   PDF (2221KB) ( 1724 )   Save Support Vector Classification has shown great performance in practice as a two class classification methodologyHowever,it is required that every input must be exactly assigned to one of these two classes without any uncertainty. In this paper,we propose USVC early-warning algorithm on expert advices,which is able to deal with the training data with uncertaintyThe application field of our algorithms is,wider than the SFVM method,although uncertainty is also considered thereMoreover,early warning of grain security is solved by USVC algorithm.
