在我国的房地产交易中、购房者总是对商品房质量存在很大的疑虑、这主要由于开发商总是试图掩饰商品房的缺陷及其不利因素,购房者对于房屋的实际质量和价值缺乏足够的认识,并且在一定程度上．这种知识的缺乏不是单纯靠购房者的努力能够弥补的．因此我们有必要对商品房交易行为进行一定的分析。本文即用不完美信息动态博弈对此进行了分析,为规范商品房交易提供了一些可资借鉴的建议。 相似文献

The mediating role of consumer trust in an online merchant in predicting purchase intention 总被引：1，自引：0，他引：1
It is widely known in related literature that trust in a merchant reduces the perceived risk of an online transaction. However, there are theoretical reasons to postulate that the perceived risk acts as a barrier to consumer trust. Furthermore, existing studies suggest that trust is an important predictor of purchase intention. Thus, this research aims at investigating the mediating role of consumer trust in an online merchant in the relationships between components of perceived risk and purchase intention: (1) examining the total effect without mediation, and (2) examining the mediation effect. When we probed the total effect, the findings revealed that performance, psychological, financial, and online payment risks have a significant negative influence on purchase intention. On the other hand, an examination of the mediation effect indicated that trust in an online merchant completely mediates the effect of performance risk, but partially mediates that of the psychological risk. Given the mixture of unmediated as well as mediated effect of perceived risks on purchase intention, the paper concludes that efforts, made by online merchants, to lessen certain types of risk will first improve consumer trust, and then ultimately, increase consumer's intention to buy online. 相似文献

Network structure, self-organization, and the growth of international collaboration in science 总被引：12，自引：0，他引：12
Different approaches have been used to analyse international collaboration in science but none can fully explain its rapid growth. Using international co-authorships, we test the hypothesis that international collaboration is a self-organising network. Applying tools from network analysis, the paper shows that the growth of international co-authorships can be explained based on the organising principle of preferential attachment, although the attachment mechanism deviates from an ideal power-law. Several explanations for the deviation are explored, including that of the influence of institutional constraints on the mechanism of self-organisation. 相似文献
