关于煤层稳定性评价方法的探讨

文章以贵州省黔西县金家寨煤矿地质普查工作为例,利用矿区煤层厚度的变化、煤层的可采性、煤层结构等指标,对矿区内可采煤层的稳定性进行了综合性定量评价,并与传统的定性评价方法进行了对比探讨。该方法做到有据可循,改变了目前模糊的定性评价方式,使煤层稳定性的评价更加科学合理,促进煤层稳定性研究工作。     

为构建和谐企业充分发挥工会组织作用

当前时期,如何将企业与广大职工组合成为目标共定、效益共创、责任共负等的利益共同体,把生产经营目标作为企业和职工双方的共同目标,这都要求工会在协调各种关系方面发挥作用。在构建和谐企业进程中,工会如何突出维护职工权益职能值得深思。     

后发国家探索独立自主发展道路的优劣势表现与路径选择

后发国家的工业化进程受历史、社会结构以及要素禀赋等多重复杂因素影响,存在后发优势和后发劣势。准确理解后发优势和后发劣势的动态演进过程和内在逻辑关系极其重要。对此,发展经济学不仅应呼应和回答后发国家在后工业化时期的技术创新与制度变革的结构性问题,而且应重点研究后发国家不同阶段的后发优势和后发劣势的变化问题。以中国为代表的后发国家在工业化进程中充分发挥后发优势,经过艰辛探索与实践创新,走出了一条独立自主的发展道路,取得了令世界瞩目的经济发展成就,为其他后发国家技术创新、制度变革等具体路径提供了有益参考。本文结合前期研究,围绕中国三次比较有影响力的关于后发优势、后发劣势的争论,总结提炼中国的成功经验,提出后发国家应聚焦科技自主创新与制度改革,以结构性改革为突破口发挥自身优势,促进后发国家内生性增长,进而在未来发展过程中尽快补齐短板,加快探索适合国情特色、适应世界经济发展潮流的发展模式和发展道路。本文建议立足后发国家的成败案例和不同模式,深化后发优势与后发劣势的比较研究,构建新的发展经济学范式与实证研究体系。

基于分阶段ARMA模型的东莞市GDP数据分析与预测

依据我国改革开放进程分别对东莞市1978-2015年GDP数据和1992-2015年GDP数据建立了ARMA模型,两者对比,后者的模型形式简约且预测结果优于前者。对比两阶段数据的自相关系数显示,1978-2015年数据的各阶自相关系数大于1992-2015年数据的同阶自相关系数。

Information asymmetry, speculation and foreign trading activity: Emerging market evidence

This paper provides evidence on the relation between private-information-based trading and foreign trading activity on the Istanbul Stock Exchange (ISE). We use a recently developed model that utilizes information in volume-return dynamics of individual stocks and show that variables such as size and Tobin's Q explain the extent of speculative activity across firms traded on the ISE. We present evidence supporting the notion that foreign trading activity is associated with informed trading on the ISE. Implications of our findings for emerging markets research are also discussed.     

Reporting issues challenging the National Roads Authority of Papua New Guinea: the case for using local indigenous mechanisms

For many years, considerable resources have been expended on the National Roads Authority of Papua New Guinea to help build up and maintain the road assets for the economic and social development of Papua New Guinea. Evidence from the audit reports of the auditor-general of Papua New Guinea suggests that there appears room to improve the reporting and accountability of this authority through local indigenous mechanisms. The paper is an important warning for donor organizations about opportunism and how to prevent it (and worse).     

The effects of firm actions on customers’ responses to product recall crises: analyzing an automobile recall in China

In times of product-harm crises, the involved firms always employ some countermeasures, such as releasing messages relevant to their response actions. To evaluate the influence of these messages on the perceptions and behavioral responses of corporate customers relative to the recalls, we conducted a case study of the Volkswagen automobile recall in China in 2013. Guided by the protective action decision model, we developed a conceptual model to first study customers’ responses to the recall crisis. Based on this model, we further examined the influence of two types of firm actions, namely technical and ceremonial, on the customer crisis-coping process. Results show that product experience, risk perception, and information seeking significantly influence customers’ behavioral intentions during the product recall crisis. Customers in the technical action group exhibit a higher level of risk perception based on their product experience and have a higher likelihood of seeking information. However, information seeking fails to influence their behavioral intentions. Ceremonial actions overcome the disadvantages of technical actions, but customers’ lack of solution information should be met. In this sense, crisis-involved firms are encouraged to employ a combination strategy including the implementation of the two types of firm actions and then promptly release the messages containing both actions.     

子女照料、家庭负债与已婚女性就业——基于Becker家庭决策模型的微观实证

子女照料与家庭负债对已婚女性的就业选择具有重要影响。为此,在Becker家庭决策模型基础上,建立资产负债约束下已婚女性“子女照料—闲暇—就业”效用最大化决策模型,利用2016年CFPS数据分析发现：子女照料对已婚女性就业概率及周工作时间存在负向影响,且家庭的银行负债对子女照料与已婚女性就业的关系存在负向调节效应。因此,在鼓励女性生育的政策背景下,政府需要综合考虑子女照料负担与家庭负债约束,制定更加有效的已婚女性就业保障政策。
