我国中小企业融资需求与资本结构选择研究——基于中小上市公司的实证检验

通过对影响中小企业融资需求与资本结构选择的特征因素进行逻辑分类,通过样本选择来控制一定层面的特征因素,进而对中小企业融资需求与资本结构选择进行一般性研究。研究发现我国中小企业的融资需求偏好股权融资,中小企业规模、成长性、市场竞争能力、盈利性、非债务税盾与资产担保价值对中小企业融资需求与资本结构选择具有重要影响揭示了尽管资本市场拓宽了中小企业的融资渠道,股权融资需求得到较大程度的满足,但是并不能满足中小企业成长性融资的内在需求,高成长企业被迫选择以银行信贷为主的债权性融资,从而带来财务杠杆的提高,增大企业财务风险,因此对于本身就具有高风险的中小企业来说,提高风险价值管理水平,科学进行融资决策具有至关重要的意义。     

新疆制造业品牌运营的问题及对策

针对近年来新疆制造业在品牌运营中存在的品牌数量少、品牌缺乏个性等问题,在其相应成因分析的基础上,认为做好品牌设计、搞好品牌定位、品牌推广和维护是新疆制造业品牌运营的必然选择。从政府和企业的角度提出了新疆制造业进行品牌运营的思路与对策。     

“X是（的）”语法化及其语势层级

在描写现代汉语中“X是（的）”语表形式的基础上，考察了“X是（的）”短语词汇化和语用法的固化过程，从而把用于委婉责备的“X是（的）”与它的同形异构式区分开来。列出用于委婉责备的“X是（的）”内部各形式表示责备语气的强弱等级。     

New balanced sampling plans excluding adjacent units

Hedayat et al. [1988a. Sampling plans excluding contiguous units. J. Statist. Plann. Inference 19, 159–170; 1988b. Designs in survey sampling avoiding contiguous units. In: Krishnaiah, P.R., Rao, C.R. (Eds.). Handbook of Statistics, vol. 6. Elsevier, Amsterdam, pp. 575–583] first introduced balanced sampling designs for the exclusion of contiguous units. Sampling plans that excluded the selection of contiguous units within a given sample, while maintaining a constant second-order inclusion probability for non-contiguous units, were investigated for finite populations of N units arranged in a circular, one-dimensional ordering. There remain many open questions about the existence of such plans and their extension to plans excluding adjacent units. We present new generation techniques and new balanced sampling plans for the exclusion of adjacent units under finite, one-dimensional, circularly and linearly ordered populations.     

从“亲亲相隐”制度看中国传统法律思想的基础——兼论“亲亲相隐”制度于当代重构之法律思想基础

“亲亲相隐”制度是我国传统社会的一项重要的法律思想,是传统社会中礼治与儒家文化相结合的产物。而在当代许多国家都普遍设立了关于亲属间相容隐的制度时,这一制度在我国的刑法和刑事诉讼法领域却是一个空白,但完善这一制度又是必要的。文章通过对传统“亲亲相隐”原则在制度和理念上的分析,得出在传统与现代的法律理念之间,要重构“亲亲相隐”制度,应如何考虑对建构这一制度在思想基础上的取舍。     

Dynamic Pricing to Minimize Maximum Regret

We consider a dynamic pricing problem that involves selling a given inventory of a single product over a short, two‐period selling season. There is insufficient time to replenish inventory during this season, hence sales are made entirely from inventory. The demand for the product is a stochastic, nonincreasing function of price. We assume interval uncertainty for demand, that is, knowledge of upper and lower bounds but not a probability distribution, with no correlation between the two periods. We minimize the maximum total regret over the two periods that results from the pricing decisions. We consider a dynamic model where the decision maker chooses the price for each period contingent on the remaining inventory at the beginning of the period, and a static model where the decision maker chooses the prices for both periods at the beginning of the first period. Both models can be solved by a polynomial time algorithm that solves systems of linear inequalities. Our computational study demonstrates that the prices generated by both our models are insensitive to errors in estimating the demand intervals. Our dynamic model outperforms our static model and two classical approaches that do not use demand probability distributions, when evaluated by maximum regret, average relative regret, variability, and risk measures. Further, our dynamic model generates a total expected revenue which closely approximates that of a maximum expected revenue approach which requires demand probability distributions.     

低磁场回旋速调管的空间电荷效应

本文建立了考虑直流空间电荷效应和交流空间电荷效应的低磁场(大回旋半经)回旋速调管扰动理论。在漂移区中考虑直流空间电荷场的影响。我们发现电子运动在该区服从一振荡方程;进一步在输出腔中计及了交流空间电荷场对注一波换能的影响。文中求得了相应的电子群聚、注一波互作用功率及增益的表达式,并进行了讨论。     

“以支定收”还是“以收定支”:我国财政收支关系的实证研究

通过对我国财政收入与支出的时序变量建立协整与误差修正模型,实证研究我国的财政收支关系中到底是以支定收还是以收定支,确定这种收支之间的因果关系对采取财政政策的借鉴意义。研究将回答,我国财政收入是财政支出之间是单向格兰杰因还是双向格兰杰因,抑或互非因果关系,并在此基础上指出财政政策的作用方向,为真正建立符合的现代市场经济的财政观提供经验证据。
