Qualitative indices in multi-objective decision can usually be evaluated and measured by mathematical methods or models, but the obtained results are sometimes inaccurate because of fuzziness of indices. To improve the accuracy and reliability of the evaluation results, set-value statistic principle is applied, and accordingly four evaluation methods are obtained. Meanwhile, these methods are compared briefly.

2011 IEEE International Conference on Waste Recycling,Ecology and Environment(ICWREE 2011)

作者： Chuanhui LIAO * school of economics and management southwest university of science and technology Mianyang China

The author test the relations of carbon disclosure and performance of carbon reduction by regression. Using the data taken from the CDP report 2009, 2010 and Ft500, the results indicate that the relationship between carbon disclosure and the performance of carbon reduction is the significant positive relationship, which means the more the performance of carbon reduction companies, the more disclosure made. The results also found that industries with higher sensitivity to environment do not tend to provide more extensive carbon disclosures;companies with higher market value and asset tend to provide of more carbon disclosure.

Perceived risk is an important concept in consumer behavior in online shopping. It impedes the adopting online shopping. A structure model with seven factors of consumer's perceived risk in online shopping is developed in this paper.

Journal of Southeast university(English Edition) 2008年第S1期24卷 180-186页

作者： Li Yajing1 Zhu Hongquan2 Luan Mingjing2(1 school of economics and management, university of Electronic science and technology of China,Chengdu 610054, China)(2 school of economics and management, southwest Jiaotong university, Chengdu 610031, China)

This paper explores the disposition effect, the tendency of investors to hold losing investments too long and sell winning investments too soon, by analyzing a unique data set that consists of the buying and selling positions of open-end fund investors in China. Results show that investors' buying and selling behaviors are significantly affected by fund performance. The reasons that lie behind such results are mainly related to the non-persistence of fund performance. When fund performance is non-persistent, investors are not clear about the future returns on funds. So, investors, especially individual investors, would have to realize the profits on hand immediately. Meanwhile, fund investors are highly sensitive to fund age and loading fees, but not sensitive to management fees charged by funds when they buy or sell fund shares.
