Regional Unemployment in Transitional China: A Theoretical and Empirical Analysis

The purpose of this paper is to explain the pattern of regional unemployment in transitional China. A model is developed to explore how urban unemployment in the provinces is influenced by peasants' wages, formal sector wages, and the size of the formal sector. Evidence from panel data suggests that a significant indicator of high unemployment rates is greater Urban–Rural Income Inequality within the province. The hypothesis is that the urban–rural income gap produces migration, and more rural migrants substitute for urban workers, causing further urban unemployment.Since the economic reforms began in 1978, the non-state owned enterprises have been carrying an increasing weight in the economy, and they have contributed significantly to the rapid economic growth of China. Empirical evidence shows that economic reforms have reduced unemployment. The provinces that are still heavily dependent on the state sector are therefore more likely to experience higher unemployment.

基于交易或事项分类设计所得税会计债务法分析

本文从影响所得即净资产变动(基于经济收益观)的交易或事项出发,分析了时间性差异与暂时性差异的成因,探索利润表债务法与资产负债表债务法的设计思路。在此基础上,提出易于与税法衔接简化的资产负债表债务法——发生额资产负债表债务法。     

供应链分销系统奖金优化与仿真分析

研究由多个制造商与一个零售商组成的分销系统，他们以各自的利润最大化为目标，制造商给零售商提供奖金激励，零售商提供对应于奖金激励的服务水平，制造商需要进行为零售商提供多大奖金激励的决策。利用强化学习的启发式学习算法来优化制造商应提供的最优奖金激励。     

发展现代物流的可行性与必要性

现代物流作为先进的组织形式和管理技术，在世界成为企业生存和发展的手段。我国现代物流处于起步阶段，如何促进我国现代物流的发展，已是我国物流业一项重要课题。     

我国物流组织与物流体系的创新与发展

现代物流作为“降低成末的最后边界”，从组织看，是由流体、载体和流向三要素构成，从运作看，体现储存、运输和配送三大功能；从投入产出看，寻求降低物流成本和提高服务水平的动态均衡。供应式物流到订购式物流是我国物流组织创新的内容，其发展战略是即时物流、协同或一体化物流、高度化物流。物流体系创新应从行政区域、组织到按经济区域组织来实现。     

On estimating the reliability after sequentially estimating the mean: The exponential case

Sequential estimation problems for the mean parameter of an exponential distribution has received much attention over the years. Purely sequential and accelerated sequential estimators and their asymptotic second-order characteristics have been laid out in the existing literature, both for minimum risk point as well as bounded length confidence interval estimation of the mean parameter. Having obtained a data set from such sequentially designed experiments, the paper investigates estimation problems for the associatedreliability function. Second-order approximations are provided for the bias and mean squared error of the proposed estimator of the reliability function, first under a general setup. An ad hoc bias-corrected version is also introduced. Then, the proposed estimator is investigated further under some specific sequential sampling strategies, already available in the literature. In the end, simulation results are presented for comparing the proposed estimators of the reliability function for moderate sample sizes and various sequential sampling strategies.     

城区特征对房贷的影响

城区特征通过多种途径影响商业银行住房抵押贷款决策.商业银行可以根据城区特征判断一个城区的住房抵押贷款违约风险,进而确定对该城区的最低首付款比例或拒贷率.通过分析国外城区特征对商业银行住房抵押贷款决策的影响机制,联系我国实际情况,指出我国商业银行根据城区特征进行住房抵押贷款决策具有合理性,建议商业银行密切关注城区住房价格波动率,并建议政府限制中低收入城区商业银行的数量.
