In the second place, this paper uses the financial data reported by China's private listed companies and statistical analysis skills to test the theories and hypotheses. The research collects all required data from 2000 to 2002, examines the profit ability, the gain ability, the repay ability, and the cost control ability for all sampling listed companies by using Paired-Samples T test in the quantitative analysis section. The results show that these listed companies'profit decreases, income increases, repay ability enhances after the companies go public. Finally the paper takes the non-operating expenses as the illustrating index for the cost control capability of the companies to demonstrate that there is an obvious increase of non-operating expenses after getting great amount of money in IPO, in this sense it can be stated that there is the intendancy of low capital utility rate in private companies.

研究选用了描述性统计分析方法对样本企业IPO前后时段的财务指标进行了对比考查，并运用配对样本t检验方法进行了显著性检验，研究结果表明民营企业在IPO前后的盈利水平总体上是显著下降的；同时研究也显示虽然获利水平出现了小幅上升，但这是由于企业通过IPO融资增加了投资规模导致的；企业的偿债能力在IPO之后有明显的好转；研究最后以营业外支出作为企业成本控制能力的解释指标，发现企业在IPO上市融得大量资金后对主营业务以外的支出有明显的增多，可以判断民营企业存在资本利用效率低下的现象。

Three-way data analysis (Chapter 1 to 5 of Part Ⅰ): In terms of the symmetry of trilinear model, several statistical criteria including coupled vectors resolution errors and slice-wise diagonalization error are proposed for statistically plausible resolution of trilinear data. These criteria form the basis for the development of novel trilinear analysis procedures. In Chapter 1 the coupled vectors resolution method is developed for second-order calibration.
