经济转型、行政性一致同意与税收立法--一个内生法律理论的视角

我国行政性一致同意的税收立法模式内生于行政性一致同意的政府主导型转型路径。这一税收立法模式有助于积累税收立法经验,对转轨经济做出迅速的税收立法反应,建立税收秩序,但该模式可能导致税收立法的行政控制,导致税收立法行为的策略性和非规范性,进而影响一个国家长期发展绩效。行政性一致同意的税收立法模式是一种与转轨经济相适应的过渡模式,而我国的经济转轨的过程,同时是立宪性一致同意税收立法模式的逐步建立过程。     

财务会计外包服务市场探析

外包(Outsourcing)起源于20世纪70年代。在讲究专业分工的欧美国家,企业为维持自身竞争核心能力,为避免企业因人力不足而产生的困境,将企业的非核心业务委托给外部的专业公司,以降低营运成本,提高品质,集中人力资源,提高顾客满意度。因此,可以把企业外包定义为:依据服务协议,将某项目服务的持续管理责任转嫁给第三者执行。在市场竞争日益激烈的环境下,外包作为一种可以有效提高企业竞争力的策略,已经越来越多的被予以运用。     

The efficiency of IPO issuing mechanisms and market conditions: evidence in China

This study conducts a comparison analysis on the efficiency of bookbuilding and secondary market proportional offering (hereafter, SMP offering) in the China stock market. SMP offering as described in this paper is not a follow-on offering, but an initial offering applicable to investors in the secondary market. Specifically, as a unique type of fixed price offering, SMP offering only allows the existing investors who are holding shares (of any listed firms) in the secondary market to subscribe to IPO shares. The amount of IPO shares available to be subscribed by the existing investors is proportional to market value of shares held by them in the secondary market. We find some interesting evidence showing that, compared with bookbuilding, SMP offering is more efficient for pricing IPOs, particularly, in a volatile market. SMP offering leads to lower underpricing and lower cross-sectional variation of short-run returns of IPOs. Also, SMP offering is better able to counteract adverse market conditions in the form of low market return and/or high market volatility. Our results are robust to various alternative tests, e.g., the Heckman (Econometrica 47:153–161, 1979) two-stage procedure and an out-of-sample test, after controlling for the problem of endogeneity and for the influence of the exchange of listing, respectively.     

云会计环境下的大数据审计相关问题思考

在会计信息化不断发展的今天,云会计由于成本低,效率高,资源集约等特点被越来越多的企业认同和运用.与此同时,云会计环境下,数据规模大种类多,信息安全易受到威胁.为了评价和鉴证云会计信息系统中存储的海量数据是否真实完整可靠,大数据审计应运而生.大数据审计是对云会计信息系统内部控制的有效性和存储在云中大数据的公允性合法性进行审计.论文介绍了大数据审计产生的背景,自身的优势和局限性.依据截止2017年5月,41家被出具非标准审计意见的上市公司为样本,具体阐述了大数据审计实施流程,构建并检验大数据审计分析模型.     

外资风险投资在中国内地投资影响因素研究

借用国际生产折衷理论,并结合不确定性理论研究影响外资风险投资决策的因素,结果发现:当中国内地与投资国(地区)的创业水平越高、文化差异越小时,外资风险投资的投资可能性越高;创业水平越高,投资规模和数量越大;文化差异越大,外资风险投资的数量越多.本文建议进一步改善中国内地创业环境,以更多地吸引外资风险投资,提高企业创新动力,推进优质企业国际化.     

烟梗投料麻绳剔除装置的设计与应用

针对目前新疆卷烟厂制丝车间梗线生产HT梗时,采用麻袋封装,在梗条的运输过程中麻袋破损,导致梗条中混有麻绳,目前采用人工分拣,劳动强度大的问题,本文设计了一种烟梗中麻绳麻丝杂物装置,该装置由行星辊,耙钉,粘条,传动轴,行星辊,升降丝杠,机架等组成.装置制作完成后为了验证该装置的加装后的麻绳剔除效果,同时找到满足工艺要求条件下的最佳剔除效果,进行电机转速,工作时间和物料重量三因素三水平的正交试验.试验结果表明,该装置剔除效果最佳时的工作状态组合为:电机转速n为72r/min,工作时间t为2h,物料重量m为6000kg,继续优化验证试验,试验值与理论值相差小于5％,最佳结果满足烟梗中麻绳剔除分拣要求.     

Timing decisions of new product preannouncement and launch with competition

We develop a game-theoretic model to study the timing of new product preannouncement and launch under competition. We derive firms’ optimal timing choices and conducted a numerical analysis to evaluate the role of various factors. Our analytical and numerical results showed that anticipated competitor’s timing choices are the most significant factors. A firm should not preannounce early unless the preannouncement is effective in creating pent-up demands. However, the preannouncement and launch should be rushed if the quality or profit margin of the new product is high, and postponed if the market share of the existing product is high. The market leader should preannounce earlier in a simultaneous game than in a sequential game, but the opposite for the market follower. Data collected from the microprocessor industry validated our model.     

博士毕业生就业选择研究:综述与展望

就业作为博士教育运行机制的终端,是对博士生培养质量的重要检验.已有博士毕业生就业选择研究主要围绕整体就业率、就业选择趋向、就业选择差异性等方面展开,达成了一些共识,为了解博士毕业生就业选择提供了有效途径.但相关研究在数据来源以及研究内容上普遍存在年限单一、院校单一或分析维度单一等问题,未来研究需采用多年限、多院校、多维度分析的方式对博士毕业生就业选择进行更加准确、深入、全面的呈现.
