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.     

基于对立品类的卷烟新品类营销模型研究

品类度代表着具体商标区别于其他商标的程度,是提升品牌价值的关键。卷烟新品在营销时,以对立品类理论指导营销活动能够帮助新品卷烟在市场竞争中脱颖而出。论文分析了消费者选购模型,结合品类度的基本特征,认为对立品类竞争是新品卷烟营销的可靠方案,并提出具有现实意义的指导意见。

China's Anti-Corruption Campaign and Financial Reporting Quality

We examine the impact of China's anti-corruption campaign on firm-level financial reporting quality (FRQ). As an important component of the anti-corruption campaign, in October 2013, “Rule 18” was issued to prohibit party and government officials from serving as directors for publicly listed firms. The regulation led to a large number of official directors resigning from their roles as directors involuntarily. As such, Rule 18 has effectively weakened, if not fully discontinued, the political connections of the firms that previously hired officials as directors. Our empirical analyses employ a difference-in-differences research design with firm fixed effects and propensity-score matching to examine the pre- and post-period FRQ around the enactment of Rule 18. We find that, compared to propensity-score-matched control firms, FRQ of firms with resigned official directors increases after Rule 18. Further evidence suggests that the impact is stronger when firms are located in regions with more developed financial markets and in regions with higher judiciary efficiency. We also find that the effect is more pronounced when firms are non-state-owned, received preferential credits, and face refinancing pressure.     

An Empirical Analysis of Analysts' Capital Expenditure Forecasts: Evidence from Corporate Investment Efficiency*

We examine whether the information conveyed in a relatively new analyst research output—capital expenditure (capex) forecasts—affects corporate investment efficiency. We find that firms with analyst capex forecasts exhibit higher investment efficiency. This effect is stronger when the forecasts are issued by analysts with higher ability or greater industry knowledge. Moreover, the effect of capex forecasts on investment efficiency varies with the signals they convey about future growth opportunities—positive-growth signals are more effective in reducing underinvestment, while negative-growth signals are more effective in reducing overinvestment. Cross-sectional tests suggest that these effects operate at least in part through both a financing channel and a monitoring channel. Taken together, our results suggest that analysts' capex forecasts convey useful information about firms' growth opportunities to managers and investors, which can facilitate efficient investment.     

国防工业军民融合发展国际化：路径与实现

国防工业军民融合发展国际化是发达国家国防工业发展的普遍做法。从已有研究成果看,学界尚未就国防工业军民融合发展国际化问题进行专门系统的研究。依据学界对国际化和军民融合发展的理解,界定国防工业军民融合发展国际化基本内涵,在此基础上将国防工业军民融合发展国际化基本路径区分为国防工业军民融合发展“引进来”和“走出去”,揭示军用民用产品跨国贸易、军民品跨国研制生产、军事民用领域跨国投资、军民领域跨国经济合作、军民标准运用跨国对接、军工民用企业跨国联盟等国防工业军民融合发展国际化实现形式的内涵机理。推进国防工业军民融合发展国际化,有助于更好地利用国内外军民两种资源优势、发挥国内外军民两个市场作用,从而加快国防工业军民融合深度发展,提高国防工业发展质量效应。
