我国数字经济发展战略与路径研究--基于国际经验的考察

当前我国经济正处于增速放缓、结构升级及经济发展动力转换的新常态阶段。寻找新的经济增长点和新动能是经济新常态时期的重要任务和目标,而发展数字经济则是目前最优的经济发展模式。2017年数字经济被写入政府工作报告,预示着数字经济作为继农业经济和工业经济发展模式之后的又一新型社会经济发展形态,已成为新常态下中国经济发展的新动能,也是推动我国供给侧结构性改革的重要抓手。但数字经济模式属于新型经济发展模式,目前尚无一个完整的发展参考体系,需要我国自寻探究发展道路。由此,本文在研究数字经济内涵及其战略意义的基础上,基于我国数字经济发展现状和国外发展战略提出了我国数字经济的具体发展路径。     

基于矿业监管博弈的激励约束机制研究

资源型城市地方政府在执行矿业监管权时，通常由于信息不对称及矿业政策执行力度范围限定与中央政府博弈。基于由此导致的矿业生产外部性，通过分析中央政府与地方政府各自的目标偏好和效益函数，利用经济博弈论和矩阵对策，试图寻求矿业监管存在问题的原因。文章尝试在利用行为经济学“前景理论”建模的基础上，借助贝叶斯理论分析，提出贝叶斯风险成本诱导机制，进而得出在该机制的激励约束下矿业监管倾向于帕累托有效。文章最后结合研究结论给出政策建议，为制定我国的能源资源开采政策提供了重要的理论参考。

Optimization of the machining economics problem under the failure replacement strategy

This paper presents a model for calculating the optimal cutting feed rate and spindle speed in a stand-alone cutting machine. The optimal cutting conditions are determined for three different objective functions—minimum expected cycle time, minimum expected cost per unit, and maximum expected profit-rate—under the failure replacement strategy, taking into account cutting tool constraints and machine limitations. We also examine the relationships between the optimal solutions, and present the efficiency range of feed rate.     

Grief recovery from the loss of a family business: A multi- and meso-level theory

In this article I develop a multi- and meso-level theory of grief recovery time from the loss of a family business. The multi-level aspect of the model suggests how primarily micro theories of grief and sense-making can help explain grief recovery time at the family group level. The meso-level aspect of the model provides insight into recovery from the loss of a family business by proposing how grief dynamics interact at the individual level through emotional intelligence and the family group level through emotional capability. By supplementing theories of grief with those of sense-making, the model provides a deeper understanding of the grief recovery process. This model has implications for scholars and practical implications for family business members and the family unit.

Estimation of the change point of a distribution based on the number of failed test items

This paper discusses the family of life distributions with failure rate functions which decrease initially until a change point and remain constant thereafter. The paper focuses on the estimation for the change point of the failure rate function. While point estimation of the change point of the failure rate function has been discussed by some authors, one can hardly find any existing work on the interval estimation of the change point. In this paper, a method for constructing approximate confidence intervals for the change point is proposed. The proposed approximate confidence intervals are based on the number of failed test items at or before a fixed inspection time. Received: September 1999     

Firm leverage decisions: Does industry matter?

We use a standard capital structure mode l to investigate the firm leverage decisions of 1620 companies listed in the Australian Securities Exchange (ASX) across a span of 13 years (2000–2012), dividing the sample into mining and other industries (non-mining). We also test for significant differences in leverage decisions between these two groups by applying a dummy variable approach. Our findings show that fundamental differences exist between mining and non-mining companies when making leverage decisions. We find evidence that mining firms are more sensitive to profitability and asset tangibility where neither profitability nor asset tangibility has significant association for non-mining firms. Overall results suggest that industry-type does matter for firms making leverage decisions.
