In this research, the SOLO (Structure of the Observed Learning Outcome) Taxonomy presented by Australian scholars Biggs and Collis (1982) was adopted, and students studying the fifth and sixth grades in Taipei area were chosen as research targets.This study was primarily implemented with a quantitative analysis and supported by a qualitative analysis. In order to carry out the research, a questionnaire had been designed with criteria suggested by Jones et al.(2000), including "describing data","organizing and reducing data","representing data" and "analyzing and interpreting data." This questionnaire consisted of open-ended questions, and after analyzed with qualitative methods, the responses were classified and scored based on standards set in SOLO Taxonomy. Then the quantitative method "Partial Credit Analysis" from Rasch model was adopted in examining the reliability, validity and consistency of outcomes from the qualitative analysis.
提出的统计思维架构-「描述资料」、「组织及简化资料」、「呈现资料」、「分析资料」作为评量试题的向度,题型为开放性问答题,在区分学童的答题表现方面,采用质的分析,参照SOLO(Structure of the Observed Learning Outcome)分类法的分类标准,将学童不同的答题反应进行分类,给予不同的分数,最后再采用Rasch model中的部份给分模式进行量化分析,以量化数据佐证质性分析的信度与效度,以及不同给分的吻合度。

It is on the basis of an analysis of the financing behavior that the author draw a conclusion: the optimal financing strategy is determinedby the tangency point of quantity indifference curve of financing and cost indifference curve of financing, furthermore which means to equal to for random two kinds of the marginal financing cost of financing product.
我国证券市场供求的统计范围应该主要界定为证券的一级市场,供给的统计口径应按照新的融资方式分类标难来确定。在对我国证券市场1987—1999年的实际总供求按新的口径范围计算和分析后表明:我国证券市场的平衡是一种管制性的动态平衡,在供给机制与需求机制不对称的同时,需求大于供给。
