工程造价市场信息分析及其在线系统开发

了解和熟悉某地区的市场信息对工程造价咨询公司在该地区开拓市场及造价工程师在该地区从事业务十分重要。本旨在探讨如何利用当代信息技术开发一个高性能的信息系统，它能为造价工程师提供及时的、全面和准确的市场信息(以上海地区为例)。系统开发所用的方法是一种改进的生命周期法。按照该方法，首先对工造价市场进行系统分析。然后，基于系统分析的结果，对市场信息进行分类，并在分类的基础上用超本技术建立信息模型。最后，基于模型开发信息系统。     

存款保险制度的理论依据和实施效应分析

近年来,关于我国建立存款保险制度的讨论已有明确的结果,我国存款保险的推出也似乎仅仅只是时间问题。在此背景下,本文通过对海外存款保险制度实施效应进行分析,从金融发展、金融稳定、市场惩戒和风险管理等方面,探讨了存款保险制度在处理银行倒闭、保护存款人利益、维护金融体系稳定方面的有效性及设计不当的存款制度存在的各种风险,旨在为我国存款保险制度的构建给予启示。

齿轮箱系统特性分析

利用时间序列ARMA模型求出单级齿轮箱系统的传递函数，然后求出系统正常工作、齿轮断齿、轴承滚柱磨损、轴卺守圈和外圈裂纹5种情况下系统稳态和瞬态的Bode图。齿轮箱系统特性只与本身结构有关，5种情况下同种故障的系统稳态和瞬态Boide图图像特征一致，说明可以用它来分析瞬态信号。通过图形比较，可以简单、有效地判断故障状态。

Risk Awareness of Interpersonal Trust and Entrepreneurship in China: Evidence from Survey Data

This paper aims to build a theoretical framework for the influence of risk awareness of interpersonal trust (RAIT) on entrepreneurship, and explores the influence of RAIT on entrepreneurship with the micro survey data from the Chinese General Social Survey (CGSS) 2010–2013. The study found that, individuals with higher level of RAIT, their probability of starting new business will increase significantly, and with every increase of RAIT level, the probability of business venturing increase almost 4.0%. No mediation effects of information screening and cooperative mechanism are found in the relationship between RAIT and entrepreneurship. Moreover, during the venturing process, risks accompanying interpersonal trust cannot be reduced by social input; the reduction occurs only in eastern China where the economic system and the industrial development standards are more comprehensive and mature. This paper contributes to the literatures in the following two areas: it provides new evidence on how to deal with risks in the entrepreneurship process that accompanying interpersonal trust; meanwhile, it provides an explanatory mechanism on how the risk awareness affects business venturing.     

Can Trade Agreements Curtail Trade Creation and Prevent Trade Diversion?

This paper investigates how pre‐existing preferential trade agreements (PTAs) dilute the trade creation effect and shield the trade diversion effect of new PTAs. Countries having pre‐existing PTAs enjoy smaller gains in intra‐bloc trade because of the dilution effect and experience smaller losses or even gains in extra‐bloc trade because of the shielding effect. The findings support the proposition that PTAs could be used to fend off future trade diversion.     

Properties of Census Dual System Population Size Estimators

We study parametric and non‐parametric approaches for assessing the accuracy and coverage of a population census based on dual system surveys. The two parametric approaches being considered are post‐stratification and logistic regression, which have been or will be implemented for the US Census dual system surveys. We show that the parametric model‐based approaches are generally biased unless the model is correctly specified. We then study a local post‐stratification approach based on a non‐parametric kernel estimate of the Census enumeration functions. We illustrate that the non‐parametric approach avoids the risk of model mis‐specification and is consistent under relatively weak conditions. The performances of these estimators are evaluated numerically via simulation studies and an empirical analysis based on the 2000 US Census post‐enumeration survey data.
