完善县（区）级政府采购工作的几点建议

《中华人民共和国政府采购法》第一章第一条指出，政府采购的目的，是为了规范政府采购行为，提高政府采购资金使用效益，保护政府采购当事人的合法权益，促进廉政建设。有效地实施政府采购，既是加强党风廉政建设，从源头上遏制腐败的有力手段，又是强化财政支出管理，节省财政资金的重要措施。     

基于SWOT分析的我国“碳金融”发展战略研究

"碳金融"是随着低碳经济的兴起而出现的一个全新的金融概念。在当前大力发展低碳经济的背景下,金融服务作为国民经济发展的助推器,必然要起着引导性的作用。本文通过SWOT方法分析研究我国发展碳金融的优势、劣势、机遇以及挑战,一方面为我国发展碳金融提供理论支撑,另一方面为发展碳金融提供切实可行的战略对策。     

东亚生产网络发展及其与外部市场关系考察

东亚生产网络的内在机制可以由二维分散生产理论给出一定的解释。依据该理论,作者的考察结果表明:生产网络的出现改变了东亚地区的贸易模式,引起区域内各经济体之间相互贸易的放大效应。但是,东亚生产网络的发展并没有使其与世界经济脱钩,特别是其出口的最终需求仍然高度依赖外部市场。     

基于奇异值分解的多卫星信号盲检测

针对非合作低信噪比环境下的卫星通信信号检测问题,在信号子空间维数估计的基 础上,提出了一种基于奇异值分解的多卫星信号盲检测方法。该方法充分利用奇异值与特征 值之间的关系,设计检测统计量将多个信号能量集中起来进行考虑,以适应更低的信噪比, 并从理论上对检测性能进行了推导分析。仿真结果表明,该方法简单高效,针对不同的卫星 信号,在虚警概率小于1%、信噪比为-11 dB时,盲检测概率均可达90%以上;同时能够 在低信噪比环境下适应多信号环境,且其计算量相对特征值方法减少了一个数量级,更适合 应用在星载设备上。     

股市波动对基金管理费报酬的影响研究——基于中介效应的分析

利用中介效应分析方法检验了理论假设:股市波动对基金管理费报酬有积极的影响,基金业绩在股市波动对基金管理费报酬的影响中存在正的中介效应,即基金有能力在股市波动中发掘机会来提高业绩,从而提高管理费报酬。实证结果表明,在没有增加基金业绩情况下,股市波动对基金管理费报酬具有积极影响,此结论从股市波动的视角证明了基金管理费激励机制并不是激励相容的。根据实证结果,可以从基金类型多样化、扩大管理费率范围和加强投资者教育等三个方面完善基金管理费激励机制。     

股权激励对企业非效率投资行为的影响研究——基于高管过度自信中介效应的视角

基于高管过度自信的视角考量我国上市公司股权激励实施对企业非效率投资行为的影响,结果表明,我国上市公司普遍存在过度投资和投资不足的现象,股权激励能有效抑制过度投资行为,但对企业投资不足现象具有显著的促进作用,同时,高管过度自信会导致企业过度投资行为的发生,相应地会降低投资不足行为的产生;高管过度自信是导致股权激励效果弱化的重要原因,股权激励的实施会在高管过度自信的作用下加剧企业过度投资行为,而对投资不足表现出不显著的抑制效果;良好的公司治理环境能有效抑制高管过度自信概率,也是激励效果得以发挥的重要前提。     

Leveraging foreign institutional logic in the adoption of stock option pay among Japanese firms

Research summary : We investigate why Japanese firms have adopted executive stock option pay, which was developed with shareholder‐oriented institutional logic that was inconsistent with Japanese stakeholder‐oriented institutional logic. We argue that Japanese managers have self‐serving incentives to leverage stock ownership of foreign investors and their associated institutional logic to legitimize the adoption of stock option pay. Our empirical analyses with a large sample of Japanese firms between 1997 and 2007 show that when managers have elite education, high pay inequality with ordinary employees, and when firms experience poor sales growth, foreign ownership is more likely associated with the adoption of stock option pay. The study shows the active role of managers in facilitating the diffusion of a new governance practice embodying new institutional logic. Managerial summary : Why have Japanese firms adopted stock option pay for executives? Inconsistent with Japanese stakeholder‐oriented tradition in corporate governance, such pay has been believed to prioritize managerial attention to the interests of shareholders over those of other stakeholders. However, to the extent that shareholders' interests are legitimate in the Japanese context, executives who have self‐serving incentives to adopt such pay can leverage the need to look after shareholders' interest in their firms to legitimize their decisions. In a large sample of Japanese firms, we find that foreign ownership (representing shareholders' interests) is more likely to be associated with the adoption of stock option pay when managers are motivated to receive such pay, such as when they have elite education, high pay inequality with ordinary employees, or poor sales growth.

A dynamic analysis of water footprint of Jinghe River basin

Water footprint in a region is defined as the volume of water needed for the production of goods and services consumed by the local people, Ecosystem services are a kind of important services, so ecological water use is one necessary component in water footprint. Water footprint is divided into green water footprint and blue water footprint but the former one is often ignored.In this paper waterJootprint includes blue water needed by agricultural irrigation, industrial and domestic water demand, and green water needed by crops, economic forests, livestock prochtcts, forestlalands and grasslands. The study calculates the footprint of the Jinghe River basin in 1990, 1995, 2000 and 2005 with quarto methods. Results of research show that water footprints reached 164.1 ×10^8m3, 175. 69 ×10^8m3 and 178. 45 ×10^8m3 respectively in 1990, 1995 and 2000 including that of ecological water use, but reached 77.68×10^8m3, 94.24×10^8m3, 92.92×10^8m3 and 111.36 ×10^8m3 respectively excluding that of ecological water use. Green water.footprint is much more than blue water footprint; thereby, green water plays an important role in economic development and ecological construction The dynamic change of water footprints shows that blue water use increases rapidly and that the ecological water use is occupied by economie and domestic water use. The change also shows that water use is transferred from primary industry to secondary industry In primary industry, it is transferred from crops farming to forestry, and animal agriculture. The factors impelling the change include development anticipation on econonomy; government policies, readjustment of the industrial structure, population growth, the raise of urbanization level, and structurul change of consumption, low level of waler-saving and poor ability of waste water treatment.With blue water use per unit, green water use per unit, blue water use structure and green water use structure, we analyzed the difference of the six ecologieal function districts of the Jinghe River     

人工智能技术与人力资源管理实践:影响逻辑与模式演变

人力资源管理的演变与科技革命密切相关。当前,代表最新技术力量的人工智能已进入工作场所。这些技术将如何影响人力资源管理实践,是否会带来人力资源管理模式的变革,这一问题受到学术界越来越多关注。本文采取弱技术决定论视角,重视技术的异质性、技术的应用以及情境的差异,循着"技术路线"-"技术应用"-"技术影响"-"模式变革"的框架展开研究。首先对人工智能三大技术流派进行介绍,通过纵向梳理三者的发展轨迹,深入对比三者的技术差异。接着从技术应用出发,逐一分析各流派影响人力资源管理实践的具体逻辑,并辨析这种影响是否会带来人力资源管理模式的变革。最后,本文指出人工智能时代并不存在一个绝对的人力资源管理模式,人力资源管理究竟会演化为何种模式与工作的智能化程度密切相关。在此基础上,本文尝试构建了一个人工智能时代人力资源管理模式演变的分析框架,并对甄别到的四种典型情境下的人力资源管理模式进行介绍,以期对未来研究有所启示。本文通过考察人工智能技术对企业人力资源管理的影响,在理论上丰富了人工智能时代的技术与组织研究。     

基于Holt-Winters及趋势—ARMA组合模型的粮食种植成本预测分析 ——以山东省玉米、小麦为例

该文依据1998～2012年山东省粮食种植成本资料,运用时间序列 Holt-W int ers 无季节型模型及趋 势—— ARMA 模型构成的计量经济组合模型,对2013～2017年山东省粮食种植单位面积实际生产成本进行 预测。研究表明,山东省粮食种植每公顷实际生产成本将持续加速增长,玉米将以年均增长9.48%的速度 由2013年的5 913.30元提高到2017年的8 495.25元;小麦将以年均增长8.79%的速度由2013年的7 355.55元提高到2017年的10 305元。成本高、加速增长将成为2013～2017年山东省粮食种植单位面积实 际生产成本变动的主要特征,成本的快速增长已成为制约粮农种植收益增长的重要因素。为此,提出应对 粮食种植成本过快上涨,提高农户种粮收益的对策建议:（1）积极推广集约利用主要生产资料的先进技 术,鼓励节约用肥和提高化肥效能、提高粮食单产、节约机械作业费及节水的技术进步;（2）积极培育农 村新型经营主体;（3）大力推进粮食规模化、专业化生产;（4）加快转变农业发展方式。
