互联网使用对农户多维贫困的减贫效应研究

农村多维贫困问题的研究有助于精准扶贫和乡村振兴战略的有效实施。本文基于2016 年中国家庭追踪调查数据库（CFPS）,运用A-F 测度方法对农户的多维贫困进行测度和分解,着重探讨了互联网使用对农户多维贫困的减贫效应。研究结果表明,财产性收入、农户家庭住房、生活燃料、受教育年限和社会保险等方面的贫困发生率较高;财产性收入、受教育年限对多维贫困的贡献率最大,在农户脱贫过程中起关键作用;农户家庭使用互联网对农户多维贫困的减贫效应显著,而且在高维贫困上的减贫效应更大,个体特征、家庭特征、村级特征等也都对多维贫困产生影响。因此,加大农村地区互联网基础设施建设力度,注重信息化的普及和推广,贯彻落实“互联网+”扶贫政策,能够有效解决贫困农户的“能力贫困”问题,有助于实现贫困户脱贫及脱贫质量的提高。     

谁获得了国有股权？

本文以中国上市公司国有股权协议转让为样本,考察了国有股权转让中的几个核心问题,即国有股权转让的动机、定价机制及经济后果。结果表明,中国上市公司的国有股权约以42:50:1:7的比例分别转让给了国企、私企、个人和外企,转让动机表现为经济和政治动机并存;在定价方面,转让给国有和非国有经济体的股权溢价并无显著差异,但相比转让给国企,转让给外企股权的价格较高;尽管国有股权转让不会显著影响企业绩效,但通过股权转让实现民营化的公司,其绩效会有显著的提升。

关于在施工管理中提高质量、降低风险的思考

21世纪是以质量为焦点的世纪,在建筑施工欣欣向荣的今天,提高质量、减低风险无疑是一个引人关注的话题。对质量的全面把关既是对人民负责也迎合了时代的需求,面对问题,做什么、怎样做才能提高质量,引发了笔者的思考。     

Motivations of Australian Listed Companies Effecting Share Buy-Backs

The bulk of prior research on share buy-backs has been undertaken in the U.S. As the legislative environment and capital market perception of buy-backs in Australia are different to the U.S., it is both desirable and necessary to examine the motivations of Australian share buy-backs. Contemporary Australian financial press reports, the U.S. financial management literature and anecdotal evidence provide numerous feasible motivations for a company to undertake a buy-back. In an Australian context, this article considers the following: (a) the development of the legislative framework relating to share buy-backs and why some forms of buy-back are preferred over others; (b) a set of potential motivations (reasons) for Australian companies undertaking a buy-back; and (c) the actual motivations as provided in ASX announcements by forty-four listed companies effecting sixty-seven share buy-backs over the period 1990 to 1995. Results reveal that motivations differ depending on the type of buy-back and are reasonably consistent across time. The two prime motivations for on-market buy-backs are: (a) signalling of future expectations (underpricing), and (b) an attempt to increase financial performance (EPS) and/or position (NAB/share). For selective buy-backs, the main purpose is to remove specific shareholders from the share register. Employee buy-backs are generally seen as an off-market means of providing a market for the company's shares. Finally, the overriding motivation for equal access buy-backs is as an alternative to dividends.

降低压榨油茶籽油中苯并芘含量关键加工技术的研究

针对传统压榨油茶籽油中苯并芘含量超出国家标准限量要求的情况,分析了苯并芘产生的原因和关键步骤,提出降低压榨油茶籽油中苯并芘含量的解决方案.研究表明,通过部分脱壳和控制油茶籽的干燥温度不超过45℃、炒籽不焦糊,压榨后辅以0.1％～0.2％活性炭低温吸附是有效降低压榨油茶籽油中苯并芘含量的关键加工技术.     

胜利油田电力节能降耗管理研究

本研究是在搜集大量国内外节能降耗的研究文献的基础上,以电力需求侧管理理论和智能电网理论为基础,结合胜利油田电力系统节能降耗管理的工作实际及其特点,科学地评价了其节能降耗管理的现状。通过实地调研,采用AHP／ISM研究方法分析了胜利油田电力系统在节能降耗管理发电、输配电和用电三个方面各环节存在的问题。然后针对其存在的问题逐一提出相应的节电降耗措施。本研究首次尝试将DSM和智能电网先进管理理念应用到油田电力节能分析中,后续研究应该对理论本身进行深化与梳理的基础上,根据油田电力节能管理模式的特殊性,改进研究方法,使其更加适用。     

Depreciation: A Stochastic Approach

This paper introduces a rationale for modelling physical depreciation under uncertainty and compares two variants of it. The first variant leads to a model, the 'gamma' model which has been discussed in the literature, while the second variant leads to a model, the 'binomial' model, which has not been investigated before. The binomial model is shown to approach a deterministic limit (the reducing balance method) as the depreciated asset becomes infinitely divisible. In contrast it has been demonstrated in the literature that the gamma model approaches a particular statistical distribution under these circumstances. The paper goes on to investigate the useful lives of assets under the two models, by reporting results on waiting times, none of which have appeared in the literature before.
